There is some debate about how her Semblance works. Depending on who you ask, she either:
 * 1) Fires her gauntlets when she goes into her "Rage Mode," thus creating the fire we see.
 * 2) Or she actually creates fire when going into this mode.

It is really hard to tell because in the trailer, her hair seems to glow brighter and become more intense as the fight goes on. However in the show, her hair doesn't really glow as much, if at all. Based on this, you have to wonder if maybe they changed how it works between the time the trailer was finished and when the show was released (similar to how some of White's Dust abilities don't really match Weiss' Dust abilities in the show). The only constant seems to be the red eyes triggered by burning rage.

The problem that comes with Yang's fire/explosive Semblance is that whenever she goes into this state, she always makes the same motion with her arms that appear to cause the flames and the flames look so close to the energy fired from her gauntlets, that some assume she is just firing her weapon. Others say that because you never hear the 'click' of them reloading, the fire comes from her.

In all honesty, it is very confusing. Most agree that her Semblance gives her a boost in strength and speed, but the fire thing is completely unconfirmed as of right now.
