Radioactive

"Your resistance only makes me powerful!"

- Radioactive to H.U.U. While not much is known about the villain Radioactive, it is clear that he is powerful. He has been able to fight against all of H.U.U. at once before being stopped by Ossmar and his Matter Absorption ability. He has a very wrathful personality and is focused on "feeding." He has a very strong set of abilities, including intangibility, as noted by Zach Bolt.

Personality
Radioactive is driven by primal desires such as gluttony and wrath. His primary motivation is his own survival and insatiable appetite for energy. He is not necessarily a malicious person; in fact, he would be happy to be left completely alone while he feasts. Unfortunately for Radioactive, his cravings tend to put him at odds with others who want the energy for themselves. This tends to enrage Radioactive.

Attack on the Power Plant
When a "Red Alert" was triggered by Radioactive, H.U.U. sprung into action to find him breaking and entering at the power plant. Radioactive was looking for a source of sustenance (likely radiation from the power plant), and was enraged to find resistance in the form of H.U.U. Slime threatened to arrest Radioactive and put him into Helpers custody, however, Radioactive was not ready to give in. He attacked H.U.U. and surprised them with his intangibility. When Mr. Mass sliced Radioactive, he turned tangible allowing the rest of H.U.U. to attack him. Radioactive attacked Ossmar, which triggered his Matter Absorption ability. Ossmar was able to absorb all of Radioactive's power and turn it against him. This was enough to knock Radioactive off guard to allow an unknown Helper agent to capture him.
