Hyper-Hedgehog is a fictional supervillain imagined by Radioactive Man.


When Radioactive Man was in the sewers looking for Rod Runtledge and The Undergrounders, he encountered a strange man who claimed he was a journalist doing a story on The Undergrounders. When Radioactive Man questioned him, the man got angry and transformed into Hyper-Hedgehog, a pig-looking supervillain. The two of them fought for a bit before Radioactive Man told Hyper-Hedgehog that he didn't really exist. Hyper-Hedgehog then disappeared and Radioactive Man realized that the fumes made him hallucinate him.
