Well.. I have a character that I used to use in FMA rps. My gals signature character traits are 'Dark Flames' and her state title is called the 'Darkness Flame' Alchemist.
But you see there is a large back story for my character where she alters her companion Chimeras, which her father had rescued from a research facility. A beautiful song bird with long tail feathers (Phoenix), a palm sized lizard with wings (mini dragon), a black cat, a ferret and a companion Wolf. She can alter them by making them grow and attaches her alchemy to them which they are immune to. Though in rather serious fights it is normally just her, but she adapts traits of each of her companions- to do this though she has to use alchemy on herself as well- her companions turn into tattoos on her body that she can make any size and change their locations. She normally only does this with the cat and wolf as they are the most beneficial to her speed, agility and strength.
