Semblance

Your Semblance is like a muscle. The more you practice with it, the stronger it will become. But if you only focus on one aspect of it...if you fail to test the limits of what you think is possible...then you'll never truly grow.



Semblance is a power exhibited by certain characters in RWBY.

=Description= Semblance is the manifestation of one's innate and personal power as an ability unique to each individual, with the effects varying greatly from user to user. With the sheer number of people unlocking their Semblances, it can lead to unrelated people gaining similar abilities. The nature of one's Semblance is noted as representing an aspect of their character. However, a person's Semblance can be similar to the Semblances of their parents or other family members. The Schnee family Semblance, summoning glyphs, is unique in the fact that it is completely hereditary.

According to "Aura", the fourth installment of RWBY: World of Remnant, Semblance is a more tangible projection of one's Aura. Pyrrha Nikos implied this connection when she told Jaune Arc that the use of Aura can help him to discover his Semblance. Miles Luna refers to Semblance being "fueled" by Aura. .

Those that use Semblance are able to manipulate certain physical phenomena according to the nature of their power. Some individuals, such as Weiss Schnee, are able to use their Semblance to create "glyphs" that generate some desired effect - the most prominent being sudden disruptions in movement and bursts of momentum. Ruby Rose is able to move at incredible speeds, while Pyrrha was able to manipulate magnetic forces. Some have Semblances that depend on external factors, such as Nora Valkyrie's ability to convert electricity in the environment into physical strength.

Using Dust, certain individuals can modify their Semblances with elements, such as Weiss using Myrtenaster to change her glyphs and Blake inserting Dust vials into Gambol Shroud to give Shadow clones elemental properties.

Overuse of one's Semblance for prolonged periods may adversely affect its user at certain times. This was demonstrated by Weiss on one occasion after using a series of glyphs in rapid succession to assist Ruby, subsequently collapsing afterward. This is also seen in "End of the Beginning", when Glynda Goodwitch shows signs of exhaustion from using her Semblance to fix the city.

It seems that emotional turmoil or stress can affect one's use of Semblance, either negatively or positively, as exhibited in "Destiny", where Pyrrha Nikos' Semblance activates while talking to Jaune and accidentally slams him into the stone wall. Later, in "PvP", Pyrrha temporarily warps her weapon and shield for a moment during her tournament round. This phenomenon is exhibited by Weiss in "Tipping Point", when she accidentally summons a Boarbatusk, which then attacks a party guest. The earliest and most frequent example of this phenomenon is Yang Xiao Long's habit of accidentally activating her Semblance when she is angry.

According to Winter Schnee, Semblances are like muscles and are able to grow and evolve: a clear example is her younger sister’s eventual mastery of summoning and, shown in "Haven's Fate", Emerald Sustrai creates a mental hallucination of an enormous and slightly disfigured version of Salem, affecting everyone in the room, a display of her power on a scale that Emerald has never displayed before.

A user should be unable to use their Semblance once their Aura has been depleted. Weiss could still use her glyphs in the "White" Trailer after being knocked down and bleeding, something that would imply that her Aura had been drained. However, this is an inconsistency, considering that the "White" Trailer was made early in the planning stages of RWBY, when even the concept of Dust was still in its prototype stage.

In the case of Qrow Branwen, it is possible for a Semblance to be uncontrollable and/or permanently active. Additionally, it may even be possible for a Semblance to affect one's surroundings.

Ruby Rose


Ruby's Semblance, Petal Burst, was referred to as Speed by Pyrrha in "Forever Fall, Pt.2". Ruby can use her Semblance to move at inhuman speeds that are nearly too fast for the eye to catch, making it appear as if she can teleport. She uses this ability in combat to dodge attacks, disorient enemies, hastily retreat and quickly counterattack. Her Semblance is also capable of providing limited flight capabilities.

As seen in "Best Day Ever", she is also fast enough to create a slipstream that can pick up a large number of objects, including people. Ruby can also grab hold of other people or objects and carry them off at high speeds with her Semblance.

However, she has significant difficulty with carrying heavier loads, which causes her to falter after extended use, as seen during "A Minor Hiccup" with Penny Polendina, who is later revealed to be a metal robot and thus much heavier than a normal Human of her size and body build. Another drawback to Ruby's use of her Semblance is that she doesn't appear to have full control over it, possibly due to it requiring firm concentration in order to sufficiently utilize. This is evidenced in the episode "Players and Pieces", where she is unable to retreat from a Death Stalker, as well as in "No Brakes", where she only briefly uses her Semblance in a failed attempt to escape from Roman Torchwick and the White Fang.

After the fall of Beacon, Ruby's control over her Semblance has improved. As shown in the "Volume 4 Character Short", she can repeatedly change directions in midair and attack at high speed. She also somehow exhibits the ability to seemingly burst into three separate clusters of rose petals which then flow around an opponent before reforming. The exact mechanics of this ability, however, are not yet clear, and in "A Night Off" Ruby herself admits that she doesn't really think about it when she performs this action.



In "The Next Step", Ruby uses her Semblance to directly benefit her teammates in combat. This is demonstrated when she carried Nora toward the "Petra Gigas", with the former using her upgraded Magnhild before hammering the giant's face. Such speed blurs the appearance of the two, similar to the effect when Ruby used her Semblance in "Best Day Ever".

Rose petals are often seen in her wake when Ruby uses her Semblance. As such, in "A Much Needed Talk" Qrow describes Ruby's Semblance as "being able to burst into rose petals." Sometimes, when carrying another person, the petals can take on different colors. For example, when Ruby carries Weiss with her in "Argus Limited", the petals have a red to pale blue gradient.

In "Ace Operatives", Harriet Bree tells her that her Semblance is different from other speed Semblances, saying that she thinks there's more to it than that. What this means has yet to be elaborated on.

The official board game, RWBY: Combat Ready, refers the action of using her Semblance as "Dash".

Weiss Schnee


Weiss' Semblance is Glyphs, which is the hereditary Semblance of the Schnee family. Her Glyphs have a variety of effects on objects, monsters and people. Weiss often uses her Glyphs for propulsion, as they have the ability to control motion, with the basic Glyph type exerting push forces on other objects and acting as a solid surface. The appearance of said objects changes with different types of Glyphs, three examples being her Time Dilation Glyphs, her Arma Gigas Summoning Glyphs, and her Queen Lancer Summoning Glyphs.

In "The First Step, Pt.2", Weiss uses her Glyphs as solid platforms to leap off of during her descent. She also uses a Glyph as a solid shield or barrier during her battle against the Boarbatusk in "The Badge and The Burden, Pt.2". She is also seen using her Glyphs to accelerate objects both through the air and over surfaces in "Players and Pieces" and various other occasions.

Using Myrtenaster, she modifies these Glyphs by changing which Dust vial is in use, giving a wide variety of effects. One variant of her Glyphs, called Time Dilation, speeds up actions and is the result of mixing Lightning Dust with her Semblance. Weiss is also able to confer these enhancements upon other people, as seen when she enhances Blake's speed during their fight against the Atlesian Paladin-290 in "Painting the Town...". A black version of the basic Glyph, which exerts pull forces, appears to result from the use of Dust, as evidenced by Myrtenaster's Dust chamber revolving in the "Volume 5 Weiss Character Short".

Blake Belladonna


Blake's Semblance, Shadow, allows her to create clones of herself, which push her in whichever direction she wants, even in mid-air. These clones are solid but can be dispelled easily if hit or if Blake moves too far away from them. They can also be used to distract foes or take hits for Blake.

Blake can also load Gambol Shroud with Dust to give her shadow clones offensive capability. Dust allows the clones to copy an element, with her afterimages becoming completely solid or even completely intangible depending on the chosen form of Dust. Fire Dust allows her to create fiery clones that explode on contact, ice Dust allows her to create solid ice copies of herself and earth or stone Dust allows her to create a clone of solid stone.

In "Mountain Glenn", Blake says that her Semblance is a reflection of her tendency to run from her problems rather than face them; she leaves behind an empty copy of herself which takes the hit while she escapes.

Over time, Blake's shadow clones have been shown to develop from mere afterimages into fully convincing decoys able to remain in effect for longer periods. In "Of Runaways and Stowaways", a clone is even able to exert force after being created, sending the real Blake high into the air. In "True Colors", Blake disappears after creating a clone, reappearing a short distance away after Ilia Amitola stabs the clone. It is unknown if this development results in her being propelled at such a high speed that it is harder to see her or if she can truly teleport under certain circumstances.

The official board game, RWBY: Combat Ready, refers to the action of using her Semblance as "Copy Cat".

Yang Xiao Long


Yang's Semblance, Burn, is the ability to absorb energy from the damage she has taken, and redirect it twice as hard at her opponent, effectively making her stronger with each hit she takes. She can save up the energy to use later for an even more devastating attack. When using her Semblance, she draws power from her hair. Monty Oum has compared Yang's Semblance to a "Power Meter" from fighting games, while her father Taiyang Xiao Long jokingly called her use of her Semblance "a temper tantrum".

Her Semblance does not make her invincible, as she still loses Aura when she is hit, and she can still take damage when her Semblance is active, as shown when Adam Taurus cuts her right arm off with Wilt and Blush.

In the "Volume 5 Yang Character Short", Yang was able to use her Semblance immediately after her Aura was broken.

Her Semblance also causes her eyes to change color from lilac to red, which is a side-effect of her Semblance, though it does occasionally happen outside of combat when she is angered. Another "side-effect" is that her hair glows and often becomes covered in flames.

The official board game, RWBY: Combat Ready, refers the action of using her Semblance as "Rage".

Jaune Arc


Jaune Arc's Semblance, Aura Amp, allows him to amplify his own Aura or that of others. In "Forever Fall, Pt.2", when Cardin Winchester attempts to punch Jaune in the face, there is a bright flash of light, and Jaune appears to have taken no damage. Cardin, however, holds his hand in pain. Monty Oum said it was the first hint toward his Semblance, and Miles called this "a super-strong Aura block to Cardin", having amplified it.

In "Vault of the Spring Maiden", Jaune's Semblance fully activates for the first time while trying to save the life of a dying Weiss, closing her fatal wound. In "Downfall", further details of his Semblance are elaborated upon, and it is revealed that he can amplify others' Aura by transferring some of his own. He expresses that he is not worried about running out, due to his substantially large reserves. The amplification accelerates the healing ability of the recipient's Aura, allowing it to heal extremely serious wounds, such as a broken arm or a stab wound in the stomach.

His Semblance can also amplify the effects of another person's Semblance. In "Argus Limited", he uses his own Semblance to amplify Ren's emotion cloaking Semblance, concealing the front half of the "Argus Limited" from the Manticores.

Nora Valkyrie


Nora's Semblance, High Voltage, is the ability to produce and channel electrical energy into her muscles, which lends to her absurd strength. Furthermore, she's practically immune from taking electrical damage as she simply absorbs any electrical current to fuel her strength, despite still feeling the pain. Her Semblance seemingly has no limit on how much it can absorb since she is seen taking a full blast of lightning with apparently no damage to her Aura levels.

Nora revealed to Oscar that while Ren's Semblance was unlocked via stress, hers was unlocked via being struck by lightning. This indicates that external phenomena can be instrumental in discovering and unlocking the power of one's Semblance, pending that it is something that can be triggered externally.

Pyrrha Nikos


Pyrrha had the ability of Polarity, which allowed her to command the force of magnetism. She could manipulate scores of metallic objects simultaneously and accelerate them to high velocities as well as bend and destroy them.

According to Mercury Black's analysis, once she came into contact with a magnetic object, she could remotely move it however she pleases. The food fight in "Best Day Ever" shows that she did not need to touch every single object for her to control it. Her ability was strong enough that it allowed her to manipulate normally non-magnetic metals, such as aluminum, suggesting that her semblance is not limited to ferromagnetism.

This can be seen as her spear and shield "levitate" toward her hands and she was seen controlling dozens of soda cans without touching them. She normally preferred to use this ability subtly, deflecting attacks with it in such a way that it creates the illusion of her being untouchable.

However, she was known to use it more overtly in both an offensive and defensive capacity on occasion, as shown in "PvP", where she used her Semblance to create a pulse and knock back Penny's swords. Her ability was so strong, she could lift multiple huge gears and throw them, as shown in "End of the Beginning".

Every time she used Polarity, her hands and the metallic objects that she manipulated would emit a black outline.

Lie Ren


Ren's Semblance, Tranquility, masks negative emotion, which aids him in avoiding detection by Grimm, as demonstrated the night Kuroyuri was attacked. When he first used it that night, he was hiding in a small channel, gripped with panic. His Semblance activated, and soon after, he became calm and rushed to help Nora with no interference from nearby Grimm. Once there, he activated his Semblance again, extending its effects to Nora, who stopped trembling and whimpering. A Nevermore that was perched atop the house moved down and looked around without noticing them before taking off. Even if the affected person is in the visual field of the Grimm, the Grimm does not sense the person, as demonstrated when Ren used it on Jaune and Qrow when facing the Nuckelavee.

When boosted by Jaune's Semblance, Ren's Semblance is strong enough to mask much larger objects such as an entire airship, train, and a whole crowd of people.

When his Semblance activates, the affected person's colors become temporarily grayed out.

Sun Wukong


Sun's Semblance is named Via Sun, the ability to create clones of himself. While similar to Blake's Semblance, the key difference is that rather than leaving clones behind to take the hit, his clones are able to fight for him. It is shown in Volume 2 that he must stand still and actually manipulate them into performing actions. While his Semblance is activated, his hair and tail glow yellow. His clones also have the ability to detonate on contact. In "Of Runaways and Stowaways" two of his clones help him move the Sea Feilong's head to redirect its blast away from the ship it was aiming for.

He is first seen using his Semblance in "Painting the Town...", where he creates a pair of clones that attack Roman's Paladin, though it proved rather ineffectual against the mech.

It would also seem as if his Semblance rapidly depletes his Aura, for he can not maintain it for longer periods of time without experiencing fatigue. In "Two Steps Forward, Two Steps Back", after exhausting his Aura from using four clones, he was wounded by Ilia Amitola.

His Semblance is based on one of the powers of the mythological Sun Wukong, who also had the ability to create clones of himself from strands of his hair.

Coco Adel


Coco's Semblance, Hype, allows her to use her Aura to increase the effects and power of Dust. She uses this to power the effect of her weapon’s bullets, exponentially amplifying their raw power.

Fox Alistair
Fox's Semblance is Telepathy. He uses his Semblance to communicate with his teammates. Fox’s Semblance is more precise if people are close by, and he can sense when they are nearby. When using it, the people he is conveying a message to feel as though they are being watched by something.

Velvet Scarlatina


Velvet's Semblance is Photographic Memory. It allows her to mimic people's moves, including their fighting style. She uses this in conjunction with her weapon, Anesidora, which creates hard-light copies of weapons she takes photographs of. Using this combination, she is able to use the copied weapons just as effectively as their original user. However, the weapons only last for a few hits.

Miles points out on the commentary that Velvet is one of the first characters whose weapon is extremely complementary to her Semblance.

Yatsuhashi Daichi
Yatsuhashi’s Semblance is Memory Wiping, which allows him to erase other people’s memories when he touches them. He can permanently wipe memories which are trivial in nature, such as forgetting the last few seconds and temporarily wipe important memories, which return on an equal time as to how they were wiped. For instance, if he were to wipe somebody's memory for a day, it would take a day for them to return.

Yatsuhashi uses his Semblance sparingly, only wiping seconds at a time.

Flynt Coal


Flynt Coal's Semblance, Killer Quartet, allows him to create three duplicates of himself - thus, a "quartet", including himself. Each of his duplicates appears with its own weapon, allowing him to attack with up to four times the strength simultaneously. His copies follow every action he makes a moment after he makes them. They do not appear to move on their own.

Each of his copies has their own color, himself with his "regular" appearance of cyan, plus duplicates in yellow, green and magenta. Their attacks from their trumpets also follow this color scheme.

In the episode "Never Miss a Beat", Flynt uses his Semblance to overpower Weiss during the Vytal Festival tournament doubles match.

Raven Branwen


Raven's Semblance, Kindred Link, allows her to create portals to people she has emotionally bonded with. So far, Raven has a bond with at least her brother Qrow, fellow tribe member Vernal, her former teammate and lover Taiyang Xiao Long and her daughter Yang. The portal takes on the appearance of an ovular shape consisting of swirling black and red energy. Her Semblance is first seen in "No Brakes" when she drops from a portal into the train car that Yang and Neopolitan are in. After scaring Neo away, she creates another, longer-lasting portal and slowly exits through it.

Her portals can be created in both horizontal and vertical orientation, and they can be maintained for extended periods of time.

Qrow Branwen


Qrow's Semblance, Misfortune, manipulates probability negatively, causing misfortune wherever he goes, hence its name. Unlike most Semblances, his is almost constantly active and uncontrollable, with random spikes leading to incidents as small as a glass being knocked into the floor in "New Challengers..." or as significant as a wooden beam almost falling on Ruby Rose in "Punished". Qrow has stated that his Semblance can be used to his advantage in a fight. His Semblance does not discriminate against whom it affects, including himself, which causes him to keep his distance from the people he cares about. According to Kerry, he can also choose to amplify his Semblance when he wishes, in which case it uses Aura.

Cinder Fall
Cinder's Semblance, Scorching Caress, allows her to superheat objects and manipulate their shape.

Cinder has used her Semblance to superheat powders such as sand and dust into glass and hurl them at enemies as well as alter her clothes, such as in “Dance Dance Infiltration”. She is also able to use this ability to heat and reform broken objects such as her glass weapons and arrows as seen in “End of the Beginning”.

Cinder is first seen using her Semblance in “Ruby Rose” when she causes the ground underneath Ruby Rose and Glynda Goodwitch to explode.

Neopolitan


Neo's Semblance, Overactive Imagination, allows her to create "physical illusions that can be seen by everyone". These illusions are highly convincing and shatter like glass when she dispels them or someone breaks them. Her Semblance is first seen in "Painting the Town...", where she creates an illusion wall bearing images of herself and Roman Torchwick as a distraction for Team RWBY as she and Roman escape to a nearby Bullhead.

Neo's apparent ability to teleport, as seen in "No Brakes", after Raven appears, may be faked using illusions. Throughout Volume 3, she uses her Semblance to disguise herself. For example, in "Round One", she changes her hair color, eye color and skin tone with illusions. In "Heroes and Monsters", she rids her clothing of the illusion of an Atlesian military uniform that she had appeared to be wearing since "PvP".

Later Neo displayed that she also uses her Semblance when communicating with others in lieu of her muteness, as seen in "Out in the Open" where she transformed into Ruby when arguing what to prioritize with Cinder, showing that Neo can completely transform into a another person and not just alter her own physical appearance.

Emerald Sustrai


Emerald's Semblance, Hallucinations, is "individual mental hallucinations" - the ability to modify the sensory information in a person's head while their brain is processing it. She can make one (or more) see and hear things that aren't necessarily there. In other words, instead of generating an illusion that everyone nearby can see, she causes her target to hallucinate.

Her Semblance is shown to have its limits. Whilst she seems capable of easily controlling a single mind, controlling any more than that seems to tax her own head severely. After making two paramedics mildly hallucinate in "Beginning of the End", she complains that this has given her a headache. When she manipulates at least nine people in "Haven's Fate", the number of people present, combined with the taxation on her mind, make her unconscious for an unspecified period of time.

Another limit of her Semblance is that she cannot use it while fighting. She is always seen standing still or hiding while using her power and never while fighting, even when it would be better for her to do so.

She has been shown to use her Semblance to distract her opponent, such as when she causes Coco Adel to see and hear a fake Yatsuhashi Daichi during her and Mercury Black's doubles round in the tournament. This distraction allows her to leave her hiding spot and find a much better position to sneak attack Coco.

She can also use her Semblance to lure someone into a trap, which she does to Amber in "Beginning of the End". In the episode "Fall", Emerald uses her Semblance to trick Yang into believing that Mercury is attacking her after their tournament match has concluded. Yang reacts by reflexively punching and firing her weapon to stop Mercury from kicking her. In reality, Mercury stands up, calmly walks toward her and stands in the perfect spot for the bullet she fires to strike his leg. Similarly, in "PvP", Emerald uses her Semblance to make Pyrrha see thousands of swords instead of the true number, resulting in the latter's panicked response with her own Semblance.

Mercury Black
Revealed in the episode, Lost, Mercury told Emerald that his father stole his Semblance when he unlocked it. His father used his own Semblance to steal Mercury's and claimed that he would give it back when Mercury became stronger. However, Mercury never got his Semblance back despite getting stronger, and after killing his father, Mercury still has no chance of regaining it. Not much is known about Mercury's Semblance otherwise.

Hazel Rainart


As stated by Ozpin in "Downfall", Hazel's Semblance, Numbing Agent, is being completely insensitive to pain. It allows him to stab Dust into his body without feeling the negative effects of the Dust or the afflictions themselves. To be specific, he merely does not feel the pain, but he is not invulnerable. If enough damage is caused to his body, he will be unable to continue fighting regardless of whether he feels it or not. This critical weakness is somewhat compensated by the abnormally fast rate that his Aura is replenished at.

Tyrian Callows


Tyrian's Semblance seemingly allows him to disrupt a person's Aura. When activated, Tyrian's eyes and his arm glow purple, and if he touches someone's Aura it fades away from the area he touched, leaving the victim vulnerable to attacks.

Adam Taurus


Adam's Semblance is called Moonslice. Blake describes it as receiving energy in his sword, storing it and sending it back outward. It is powerful enough to deplete the remainder of Yang's Aura and sever her arm in a single strike in "Heroes and Monsters".

Adam can retain the stored energy for some time and does not need to return the damage immediately. In the "Black" Trailer, Adam uses Moonslice on the Spider Droid after absorbing a large energy beam, disintegrating the robot. He can also create afterimages that have physical properties, as shown when he fights Yang in a forest outside Argus. In these instances when he absorbs attacks, everything red on him - such as his hair, outfit, Wilt's blade, and the markings on his mask - glow.

Sienna Khan
As revealed in RWBY: Amity Arena, Sienna's Semblance is called Grudge. Her Semblance's "grudge" activates on foes that have their Aura weakened or broken, making her stronger, faster, and more vicious when going in for the kill.

Winter Schnee


Winter has the Schnee family Semblance of Glyphs. Her glyphs have many of the same effects that her sister's does, most notably including the ability to exert forces on herself and objects, which Winter uses to move around with great agility in combat.

Like Weiss and other members of the Schnee family, she can also summon versions of her past enemies to fight for her. Unlike Weiss, she displays great mastery of this aspect of her Semblance. Her Summons are known to include dozens of miniature Nevermores, as well as a pack of Beowolfs. Her Summons take on a white-blue coloration and emit a soft glow, similar to that of sparkling snow.

Willow Schnee
Willow has the Schnee family Semblance of Glyphs. Her proficiency is not known at this time, as she has not been shown in combat.

Clover Ebi
Clover's Semblance is stated to be good fortune, which allows him to manipulate probability positively and similar to Qrow Branwen's own semblance, Clover's is also constantly active causing good fortune wherever he goes with varying effects from miraculously saving him from being crushed by cave-ins to giving him good cards in card games.

His Semblance is a reference to his allusion of "A Fisherman’s Good Luck".

Harriet Bree


Harriet's Semblance allows her to run at Super-Speed, leaving behind a trail of electricity. It appears to match Ruby's speed when both Huntresses are using their Semblances.

Her Semblance is a reference to her allusion of being the Hare from The Tortoise and the Hare.

Vine Zeki
Vine's Semblance appears to allow him to generate Aura vines from his arms, essentially extending the length of his arms.

He is seen using his Semblance to propel himself and grapple at other enemies.

His vines are a reference to his allusion of being the Vine from The Elm and The Vine as well as his name.

Elm Ederne


Elm's Semblance allows her to plant herself in place with Aura roots, causing her to seemingly be unmovable for its duration, allowing for greater strength to be put in blows. Thanks to her semblance, she is capable of holding on the Frosted Petra Gigas Geist in it's place by grabbing it's leg and successfully stop a charging Megoliath in it's tracks.

Elm's Semblance also makes her perfect in using heavy artillery type weapons due to the fact that she could easily root herself to the ground to prevent the immense recoil of such weapons to fling her right out of her feet.

Her roots are a reference to her allusion of being the Elm from The Elm and The Vine in addition to her name.

Marrow Amin


Marrow's Semblance allows him to Freeze an enemy's movements, as seen with how he froze two Centinels in place in "Ace Operatives", activating when he uses the command word "stay." This ability seems to have little to no limit seeing as Marrow was able to freeze an entire crowd of people in the episode "A Night Off", however, he must remain pointing at the target to keep them in place.

His Semblance seems to be inspired by dog commands or games.

Robyn Hill
Robyn's Semblance is Lie Detection, allowing her to see if a person is telling the truth. She holds the person's hand and envelops it in pale lilac Aura. She then asks the person a question, and if their answer is the truth, the Aura turns green.

May Marigold
May's Semblance allows her to create an area of space around her that makes everything inside invisible to the outside. May has showcased enough mastery over her Semblance to allow her to easily render up to two people invisible and create a dome large enough to shield an entire cargo truck.

Fiona Thyme
Fiona's Semblance seemingly allows her to absorb and store matter into herself through the palm of her hand. The exact upper limits to how much she can absorb are unknown, though Fiona has displayed the capacity to absorb an entire cargo truck complete with its cargo. One limitation appears to be that she must physically touch the object that she is absorbing.

Glynda Goodwitch


Glynda's Semblance is Telekinesis, the ability to move or control objects. She has a high degree of control over her Semblance and is capable of using it in combat both defensively, by stopping projectiles, and offensively, by manipulating objects and using them to attack.

Her Semblance also appears to be able to re-assemble and repair broken objects, an ability she puts to use in "Breach", sealing the entrance through which the Grimm were entering. She also uses it to repair rooms and property destroyed by the antics of Team RWBY and Qrow Branwen.

Marcus Black
Marcus' Semblance, while never showing any form of a debut as of yet, had the ability to steal other people's Semblances through unknown conditions, which he had done to his son, Mercury. This was first revealed in "Lost" by Mercury, who also states that his father was leading on the possibility of his Semblance also being able to give back stolen Semblances, though it was left uncertain if he really could.

Maria Calavera


Maria's Semblance, nicknamed Preflexes, allows her to sense everything better than most people and react to attacks almost before they happen. This higher sensory ability allows her to even react to things that are out of her field of vision, such as a lemon falling next to her or people shooting at her from behind. In the flashback in "The Grimm Reaper", she even shows the ability to pinpoint where the bullets are heading so that she can block them behind her back.

Tock


Tock's Semblance, described as an "impenetrable defensive Aura shield", made her invulnerable for 60 seconds as seen in "The Grimm Reaper". She used a stopwatch to time these 60 seconds.

When she activated and deactivated her Semblance, Tock momentarily gained a yellow glow from her Aura, which then dissipated by floating off of her in small pieces.

After activating her power, she was able to take direct hits from her opponents without even flinching. Without worrying about defense, she was able to overwhelm her opponents with her aggressive fighting style.

Carmine Esclados


Carmine's Semblance is Telekinesis, the ability to control objects with her mind. She has a great deal of control over her Semblance, allowing her to create localized weather patterns or manipulate her weapons in the air, as well as creating underground tunnels. When using her Semblance, a golden wisp appears to emit from Carmine's hands.

Her Semblance is compared to that of Glynda Goodwitch; however, it is stated Carmine lacks the same mastery over it as Glynda.

Bertilak Celadon
Bertilak's Semblance is generating heat. He has a tendency to use this to increase a target's fatigue and exhaustion, and he can also use it to form glass out of sand, then manipulating the glass to form a wall.

August Caspian
August's Semblance allows him to amplify the emotions of those around him, whether positive or negative. However, Gus can only amplify emotions the target is currently feeling, and has very limited control over his Semblance.

Edward Caspian
Edward's Semblance allows him to temporarily block a target from using their own. When he is lucid, Ed can focus on singular targets at a time. However, his foggy memory causes his Semblance to be unstable at times, affecting everyone in the area.

=Trivia=
 * Much like how the weapons in RWBY have specific noises associated with them, Semblances do as well.
 * The color of someone's Aura and Semblance don't have to match. For example Pyrrha's Aura was red and her Semblance color was black.
 * Not everyone discovers their Semblance despite being an active fighter, such as Roman Torchwick.
