Battle Scenario 1: Doc Samson, frustrated that he doesn't increase in strength or mass with elevated adrenaline levels, decides to expose himself to the legendary Terrigen Mists. He has run multiple simulations and is certain that his increased resistance to radiation will reduce the possible side effects or gradual wearing off effect associated with human exposure to the mists. Samson travels to the Blue Area of the Moon and is able to bribe and smuggle himself to the chamber of the mists when he is discovered by Medusa. Unfortunately for her, Doc Samson has already mindcontrolled the guards over the doors accessing to the mists and they place a mind-control collar onto Medusa. Just as Doc Samson is about to enter, Captain Britain arrives via a portal from the Omnimatrix.
Battle Scenario 2: Medusa arrives and she avoids being mindcontrolled yet she and Doc Samson tussle and their fight spills over into the chamber. Normally immune to the effects of the mists, Medusa has exposed cuts and bloodflow and her blood and strains of hair mingle with Doc Samson's DNA as the Mists envelope him. He is able to swing Medusa around and out into the adjoining chamber but he has successfully mutated further: he now has his original dependence on hair length as a strength marker but can grow his hair to immeasurable lengths! Medusa is unconscious when Captain Britain arrives to defeated the mutated Doc Samson!
