Alright, you are definitely a few levels higher in terms of language lol, this is a bit of a toughie
Alright, don't think of the other four, so this poke probably has a tail, fever-like symptoms and an X or cross thing?
as for something fighters have not heard, and going off the exclusive moves idea, I'll have to try to guess Pyroar
It has a tail, sure. It looks enflamed. and i guess its mane could resemble a cross?(Fire blast, ah well)
as for its exclusive move, noble roar. :/
