Superboy and the Legion of Super-Heroes (1977-) #234

The Legion hunt down a space dragon whose radioactive scales help the people of Imsk maintain their shrinking powers. When too many scales are removed at once, the dragon explodes and merges Shrinking Violet, Colossal Boy, Lightning Lad and Saturn Girl into a berserk composite Legionnaire.
