power series — fire manipulation [fīr məˌnipyəˈlāSHən] 

the ability to generate, manipulate and/or absorb fire. the user’s capabilities are unlocked by training their mutation to grow more powerful; for example, they may develop their ability so as to be able to light their body on fire without being burned themselves, though this requires a high skill level and natural tolerance. those gifted with fire manipulation are naturally resistant to fire damage—however, should they push past their developed power limit, they may begin to suffer damage from their flames, risking serious injury and possible fatality.
