Appearing first in the episode "'Til Death Do Us Part, Part II", the cartoon featured four of the Boys: Gorgeous George (the Boys' field leader), Ruckus, Slab and Hairbag; Ramrod never appeared in the series. The X-Man Morph, who had been resurrected by Sinister, had an "evil" side to his personality. "Evil" Morph was often a part-time member of the Nasty Boys, but Sinister increasingly lost control of him. The Nasty Boys reappeared in both parts of "Reunion" where, teamed with the Savage Land Mutates, they proved to be quite imposing to the X-Men whom Sinister had rendered powerless. The X-Men eventually regained their powers, freed Morph from Sinister completely, and defeated Sinister and the Boys. After leaving the Savage Land, the Boys reappeared with Sinister in all four parts of "Beyond Good and Evil". Vertigo apparently accompanied them (Sinister had given her a Magneto-inspired energy boost in "Reunion") and was made into a member, despite her female status.
