Iron Armor - He wears this during combat. It can deflect arrows or just block them from entering the body completely. It also decreases damage that Jake Demo can possibly receive.
Iron Sword - This is a very sharp weapon that Jake uses for combat. It can pierce any animal or any normal human or any alien being with skin as soft as human being without armor, fairly very quick.
Blue Cape - This is just for sheer fashion in his Iron Costume. Nothing special.
