text: Amadeus Cho is shown as being a boy genius who comes from the Battleworld domain of Greenland. He works alongside Bruce Banner (who has not become the Hulk in this reality) at the technology company Bannertech. Amadeus performs an unauthorized experiment, exposing pigs to gamma radiation. The pigs mutate into wild, large creatures which shock Bruce Banner. However, Amadeus is pleased that he has increased the pigs' size and therefore their meat content. Banner and Amadeus are then contacted by a S.H.I.E.L.D. director that explains a gamma bomb in S.H.I.E.L.D.'s possession has been stolen and launched at a civilian population by A.I.M. Banner attempts to evacuate the facility, whilst Amadeus uses flight technology to get onto the gamma bomb. Amadeus attempts to hijack the bomb, but both him and the bomb crash into the tower at the Bannertech facility. Amadeus is presumed to be killed in the explosion caused by the gamma bomb as he is not seen again.
  Another version of Amadeus Cho is when he appears as a boy genius member of the Runaways. He was a student in the Victor Von Doom Institute for Gifted Youths who comes from the Battleworld domain of the Warzone and slightly admires Delphyne Gorgon.
