Mammothman is a mammoth chojin who appeared as a member of Kinnikuman Super Phoenix's team during the final story arc of the manga. His trademark was extending tusks that seemed to have a mind of their own, and would seek out and consume any exposed blood nearby. He reappears in Kinnikuman Nisei disguised as the teddy bear Michael, teaming up with Warsman as his tag team partner to form the "Hell's Bears". His identity was hinted at when Neptuneman tasted and recognized the ice that fell out of Michael's costume.
