More Information about him here!
-His wings can vary its size, it depends on how he use them
-He can make feathers grow on his body, they protect him, so the more feathery is him, the more defense he has.
-The same happens with the red bandages, if Malphas take to much damage, he recovers faster with a bandage on the wound.
-The feathers can also change to clothes, but for combat is easier to just be feathers.
