As stated before on my project about Radiated chaos, pumps are connected to his body to carry out energy or radiation. If one of those tubes break, Chaos is near the end of his life but gives him an INSANE boost as well as having radiation in his lungs and veins. He only has a last resort which is Radiated Chaos Part 2 which like I said gives an INSANE damage boost but only a short time before the body runs out of radiation and the body eventually breaks down
