I haven't been feeling the best as of late so i offer you an emotional support Flareon
A couple of ideas i thought about him, he is always hungry because his body constantly produces heat and that needs tons of energy plus he grew to love eating so it's also because he is a glutton however it's very common to hear his tummy growl
He has an inferiority complex since he doesn't think he is as cool, talented or powerful as his brothers but he is probably the kindest and sweetest boy of the bunch with a heart of gold
It's very easy for him to feel cold but his fire powers let him regulate his body temperature and the hot weather doesn't bother him at all
While he eats pretty much anything and he would do anything for a burger and it's his facourite food
He is very cuddly and shaped like a friend, loves hugs
