StormFlower

StormFlower is Lie Ren's signature weapon. They consist of a pair of fully automatic pistols with sickle-like blades attached vertically under the barrels.

Description
StormFlower consists of a pair of concealable, green automatic handguns equipped with collapsible blades and extended magazines. When not in use, Ren stores it within his sleeves. Its muzzle flashes are green, suggesting the use of green Dust or a specialized propellant in the cartridges.

The blades are incredibly strong and sharp, able to pierce through tough material such as the bone in a King Taijitu's skull.

StormFlower's shots appear to have a fairly low stopping power, putting Ren at a disadvantage at times. This is seen in his battle with a King Taijitu, during which the projectiles fail to penetrate its hide; however, this could be attributed to the serpentine Grimm's hide being rather tough and durable.

Despite this, StormFlower's rounds demonstrate the capability to sufficiently damage the Death Stalker's tail stinger by shooting at the break in the Stalker's armor plating. This leaves the stinger damaged to the point where the other members of Team JNPR could easily exploit the weakness shortly after, killing the beast.

In inactive form, the barrels of the guns collapse inwards, and the blades fold upwards.

Trivia

 * Ren's lotus emblem can be seen on the grip panels of both pieces of StormFlower.
 * They are based on the 1911 family of handguns, fitted with extended magazines with fairly minor differences. Aside from the obvious blades, their trigger guards are elongated to connect with the blades, while the front half of the pistols are enlarged in comparison to a real 1911. It's worth noting that they're modeled with their slides in the locked-back position.
 * It is described as "dual SMGs with wind and fire blades" by Miles Luna, though Kerry Shawcross qualifies this as only "kind of". Kerry also hints that certain elements of StormFlower's original design were "saved for something else".
 * Given that Ren is an allusion to Mulan, StormFlower may be a shoutout to her skill with a bow and arrow. This can also be seen in the fact the guns, when placed together, resemble a bow or crossbow.
