Chapter 46: 46reincarnated in avatar(avatar) with gauss(warframe)' powers
Mc will be a reincarnator, friend of aang who ran away with him from the air temple 100 years ago. Mc's backstory is that mc was brought to the monks for assilum after mc "lost" most of his memories, mc will say their parents were researshers(to disquise mc's reincarnator knowlage) that have never seen bending and thought it to be mith, until their child (mc) awakened as a fire bender, mc's parents diden't hire any sort of fire bending instructor and just studied mc's powers and tryed to see what he could do with them and how they worked, it was how mc learned to make ice(mc's parents saw that mc could generate heat on top of just fire and control even existing heat, so they asked if mc could take heat away from things and freeze them, and it worked), lightning, magnetic forces, shockwaves, etc. Mc will say mc does not remember how mc met the pearson who brought mc to the air temple even if mc does remember the fact that mc's parents are dead, and that mc does remember a lot of what mc's parents tought mc, the pearson who brought mc to the air monks will say they found mc near death and brought mc to the air monks for healing
Mc will befriend aang and even teach him and others a bit of mc's knowlage(such as the chermical composition of air), mc will be the only one to stand by aang after he is revealed to be the avatar, and again, will run away with aang

I first tought it would be funny to have a fire dragon slayer from fairy tail in the avatar world so they could eat the fire benders' fire(i even have that idea still writen down and may decide on doing it someday), but i recently remember that gauss can sortof do that as well, and i thought it would be funny to have mc mistaken for the avatar due to how versitily mc's fire bending is, and mc could even teach others to branch out their powers(such as teaching lava bending to toph and a pseudo form of air bending to katara via moisture in the air)
