Skrullks

The Skrulls lure the Agents of S.M.A.S.H. to another planet where they managed to capture them in a plot to harness their gamma energy and use it to create gamma-powered Skrull soldiers. At least two of them were created before the experiment was disrupted by the team and the Guardians of the Galaxy. The two gamma-powered Skrull soldiers were defeated by Red Hulk (who dove into the mixture to become large enough to fight them).
