Dr. McLuchador

Doctor McLuchador was a doctor who was exiled from Cumberland for his extreme methods after being defeated by Dr. McNinja, who spared him the shame of unmasking in exchange for claiming his patients and him leaving Cumberland. Following McNinja's presumed death, McLuchador resurfaced, eventually attracting the attention of the leader of the Cumberland Mafia, King Radical.

In truth, McLuchador had died in anonymity several years earlier, and his identity was assumed by Dr. McNinja, who was convinced that Radical was plotting something bad and attempted to infiltrate his gang under an alias.
