I know alot of peoples that can be a possible opponent for Dark Mario:

SMG4 Mario (They both causes trouble whenever they want)

SMG3 (Two evil Mario OC's)

Eric (They both are Mario OC's that are red and black)

Shadow (Evil characters that well destroy and kill when they need)

Bowser (Evil villains that takes over the mushroom kingdom)
