Solomon Grundy is a supporting villain in Batman Unlimited: Monster Mayhem.
History[]
During Halloween, Grundy was a member of the Joker's gang in his takeover plan of Gotham City by kidnapping computer game designer, Goto Shoto, and infecting technology all over Gotham with a digital laughing computer virus. During his announcement to Gotham, Joker reveals that he named Grundy the new chief of police as part of his plan.
During Joker's parade, James Gordon keeps tricking Grundy into firing his rocket launcher in all directions by telling him that he spotted Batman, and the police eventually capture Grundy by trapping him in his own parade float. After Joker was defeated, Grundy, along with the other villains, were taken back to Arkham Asylum.
