Geronimo is a young Cherokee warrior. Initially, it was left ambiguous whether or not he was a Choujin, since he appeared to be unaffected by leaving his life-support bubble during the Golden Mask arc and his endurance was much lower than a typical Choujin. Regardless, He was able to defeat Sunshine within Warsman's body. Afterwards, it was revealed that he was human all along, and he succumbs to his injuries as a result. He was revived at the conclusion of the Golden Mask arc and after undergoing a special trial he finally becomes a Choujin. He refers to the other Idol Choujin as "senpai" and is known for his battlecry, "U-Ra-Ra!!". Geronimo appears in "Kinnikuman Nisei" as a trainer for the Hercules Academy. In the dub, he was renamed Beetlebomb and rewritten as being British in origin. He is voiced by Kaneto Shiozawa.
