He shines a lot in longer fights. The key to using him is to activate all three of his Pre-fight Abilities and maintain them, use his Sp2 to get three stacks of each Debuff and spend the rest of the fight using Sp3s. He requires a bit of ramp up, but once you max out on the Debuffs he'll destroy the opponent. You can spam Heavies all day and barely give him Power, and the Fury from his Sp3 will be massive.He doesn't necessarily require any Synergies, but it does increase his damage exponentially. The ideal team for him would be the Fantastic Four+ She-Hulk, as each Debuff additionally causes DoT, and with She-Hulk you can Power Sting the opponent.
