I leave the anatomy of my pokesona Maguwhite the Quilava.

He's a little introverted in socializing, but he's very sweet and a good friend.
When he was a Cyndaquil, he had a little informality about his fire-exit areas. Since then, when it evolved to Quilava, its exit areas become through their ears and one of the tips of their hair.
The flames that come out from their ears, come out with the same power as the flames that come out of the head of a normal quilava. And the flame that comes out of the tip of his hair, has only enough force to shine on him face.
Another data, as their flames now come out of their ears, the conduit, where the combustion comes out, passes through an area of their brain where their emotions are handled, so that, depending on the state in which it is maguwhite, him flames changing of color.

Here is the color list:
Orange (ordinary flames) -> Happy
Blue -> Sad
Green -> Scared
Red -> Angry

Oh! He loves video games, mainly RPG games, which, even with that, comes out to the outside world once in a while xDD
