Ryu with his updated Apprentice armor for EBC. He likes to keep anything he wears basics. His theory; the less of it there is, the less of it he has to deal with. And being a smaller feline, he'd rather have his agility and speed than have to put up with huge clanky armor.
Or maybe his attitude stems from the fact I like his design too much to cover it up with metal plates and stuff. We'll never know xD
