URANIUM SMAAASH

Uranium might be tough enough to bounce a bullet off his chest, but he’s actually the least dangerous of Plutonium’s gang. Radium, Polonium, and Plutonium himself are all more radioactive than him, and sometimes he just gets in their way. Nevertheless, he’s still a formidable opponent, especially with those armour plates sewn into his shirt.
