Other capabilities of Changewing that he can spit acid instead of fire, that he use to burn it's foe/predator or when he was threatened. It's spitting acid is very dangerous because it can make wood molten when he spit it that wood or other potential threat. Changewing has large of wings has also horns in his face and something like antennae as an appendage like his ears, If I notice his body, I think Changewing's shape it's more likely one of tropical plants, with his long tail like plant too.
