defeat the New Teen Titans. Although Mento eventually directs Hybrid against the Titans once again, they rebel and Mento is apparently cured of his insanity by Titan member Raven. Calhoun is never seen again, until the superhero JSA team learns that Hybrid died in the gladiatorial games staged by villainess Roulette. The original version possesses a metal epidermis, which confers superior strength and durability.
