Akira in detail here. His knife is removable and separate (also really pointy! Ouchies) and his hair is slightly transparent in a good way. He has a tummy-gash and a bandaged hand as well. Oh! And he can be taken off of his little rubble-stand, too. It’s just a foot peg keeping him there.
And you can see his buttcrack from behind. Mmmmmbuttcrack.
