So this is Ferro, he’s a protogen! Its blood is made of ferrofluid and it can’t move on its own. Instead, he uses magnets in his head to move around the ferrofluid in his body, forcing his limbs to move too. If it gets cut or throws up, ferrofluid comes out. He can then use magnets to shape the ferrofluid into weapons or whatever object he wishes. It can also soak its ferrofluid into porous objects, like a teddy bear or a sponge, and control how they move.
