The Silent Guardians!
Burly and surly, Amalgamation Man is a mutant with the ability to absorb the powers of other superheroes. He had a criminal career before joining Beethoven’s Five, and has permanently absorbed the powers of Firebreather and the Attractive Attractor. He’s already been defeated (and captured) by The Silent Guardians twice now, and he holds a pretty serious grudge.
Amalgamation Man has been revealed as Alan Easly, former star center of the KFU Dragons. He looked to have a promising career in the pros, but then he just kind of disappeared, only to resurface a few years later as Amalgamation Man.
