In the RP Ridge originated from, he was so strong that the only person who ever even defeated him in combat was one of the rulers of the entire omniverse, and Ridge even had help from two other people with OP powers like him.
Other than that moment, he has never been incapacitated by anyone. His alter ego could wipe out universes at a time alone, and without a scratch. Maelstrom was basically a god. No matter who was in control, he could fight without ever being present in a battle. If I had to choose anyone I'm familiar with that could stand up to either party in discussion here, it's him. You can imagine how nerfed he is from his RP of origin.
