Barry Allen is a main character who first appeared in RWBY/Justice League. He is based on his DC Comics counterpart Flash.

After the final battle against Starro, he decides to leave Remnant and travels to the multiverse with Justice League.


Barry is a young Tortoise Faunus with short blond hair and blue eyes. Barry's Faunus trait is lime green scales on his elbows. He wears a red short-sleeved turtleneck with a yellow sash that has an attached golden lighting symbol. Barry also wears brown leather gloves over white bandages, green pants, red boots, and a brown turtle shell backpack. To hide his identity, he wears a red mask with lightning designs on each side and lighting-styled tails.


He appears to be a heroic, kind and caring person. He is willing to welcome Ruby and Bruce to his home because he can trust them and he can tell they aren't bad people. He cares for his mother and friend Jesse deeply.

Later when Jessica Cruz was brainwashed by Starro and showed the group their traumas, Barry's trauma was revealed to be him being unable to help his mother and Jesse from being attacked by Starro's army.

Powers and Abilities

His Semblance, Constant Speed gives him the ability to become super fast by leaving a trail of lightning every time he uses his Semblance.


Barry first appears in RWBY/Justice League, Issue 5 (Digital) Issue 3 (Printed) as the true speedster Ruby and Bruce are looking for following a brief chase with Jesse Quick, who is revealed to be vetting people for the Flash as people with powerful Semblances are vanishing. Following this, Barry takes Ruby and Bruce back to his home and introduces them to his mom who invites the two newcomers to stay for the night. Barry reveals that he had hooked up the TV to the Faunus Quarter cameras to keep an eye on the place as he shows Bruce and Ruby it reveals a hypnotized Jaune and Pyrrha before the feed dies.

The group would reconvene with the remainder of Team RWBY and the rest of the Justice League in Vale, where they were attacked by mind-controlled enemies: Team JNPR, a Tentacle Grimm, and several Faunus who all wore distinct masks. They are rescued by the Green Lantern, Jessica Cruz. After making an escape, Jessica explains her origin and reveals the existence of the alien conqueror, Starro, and his plans of world domination to the group as she shows a hologram of the universe, Remnant included. There, she enlists their help in stopping Starro, explaining Starro's intent to conquer the world through the use of powerful Semblances and the might of the Atlas Military.

Shortly after, Arthur Curry takes the group to Atlantis, a city lost to time which is his home. There, they have a moment to rest while Arthur gathers intel from spies in Atlantis, discovering that Starro has aligned with Mr. Lloyd, and the two plan on taking the Dust weaponry to a hanger on the coast of Atlas. The group spends on last night in Atlantis to prepare and enjoy themselves, and in the next morning, set off for Atlas to face Starro.

Given how none of Team RWBY or most of the Justice League can fight in deep waters, the team hatches a plan to defeat Starro. Diana, being one of the few who can survive underwater, attacks Starro without being alerted due to being an Automaton, who does not register as human. With that, Arthur and Blake Belladonna draw Starro's forces to battle, where Victor Stone disables them with his technomancy Semblance. As the fight between Starro's forces and the Justice League wages, Starro calls on Team JNPR to provide himself aid.

As the Justice League’s battle against Starro continues, a mind-controlled Team JNPR joins the fray and does battle with their friends, Team RWBY. During the fight, Jessica Cruz’s mind is taken hold by Starro as she tries to help RWBY, and she begins to attack them. As the strongest member of the Justice League, Jessica uses her powers of creation to create images of Raven Branwen, Summer Rose, Adam Taurus, and Jacques Schnee to distract Team RWBY, and the various origins of the members of the Justice League.  The Trinity of the Justice League escape the fight, and lure Starro into a Dust hanger off the coast of Atlas, exploding it with Starro inside, freeing the mind controlled victims.

Starro, nearly defeated by the explosion, appears on the coast. Weakened, he loses his hold over most creatures he had mind control over. Still under mind control, Team JNPR attempts to defeat Team RWBY briefly before their mind control fades. Starro attempts one final assault, facing the entirety of the Justice League, RWBY, and JNPR, only to fail. With the alien defeated, Jessica imprisons Starro and leaves to seal him away for good as the heroes aid survivors and celebrate their victory.

With Starro defeated, the heroes return to Vale, where Ozpin congratulates and thanks the Justice League. The team goes to the Allen family’s apartment, where Bruce Wayne has provided funding for the Faunus in the area. There, they decide and actualize the idea of the Watchtower, a base of operations that can be found beyond Remnant’s atmosphere through a special Dust that Jessica Cruz has created, where the League can watch for unknown dangers and protect the world.

In Atlas, Bruce, Victor, and Weiss dedicate Bruce’s old manor to being an immense orphanage, where kids won’t be exploited. Arthur offers Jessica Cruz a gift, and the League leaves Remnant to protect the world with a goodbye to Team RWBY.


  • References and Differences from the DC Comics version:
    • The DC Comics version of Barry is a superhuman, while this version is a Faunus.
      • Ironically, the Remnant version is a tortoise Faunus, who are suppose to be very slow.
    • He has a speed Semblance that makes him super fast and leaves a trace of lightning like his DC Comics counterpart.
    • Barry, like the rest of the Remnant versions of the Justice League, keeps his DC counterpart's color scheme.
  • The given name Barry is derived from Gaelic, possibly being an Anglicised form of the personal name Báire, which is a short form of the related Irish names Bairrfhionn or Barrfind ("fair-headed", "fair-haired"). and Finbar, or Fionnbharr ("fair-topped", "fair-haired"). Which brings to mind blondes or yellows.
  • Allen is a variation of the surname MacAllen and may be derived from two separate sources: Ailin, in Irish and Scottish Gaelic, means both "little rock" and "harmony", or it may also be derived from the Celtic Aluinn, which means "handsome". Variant spellings include Alan, Allan, etc., which brings browns to mind.
