Hercules kills him. He's too strong and durable for Vader to handle. Anyone that constantly loses to that power bottom Obi Wan has no business fighting Hercules.

Vader's got all of his Legends/Canon feats in this thread, so he has the massive range advantage and there's nothing Hercules can do to even reach him, let alone pose any threat to Anakin.
^ While Herc doesn't even have any ranged options at all, unless we give him a tremendous boost and use the Chaos War SuperGod incarnation of the character... but that's a Skyfather tier.
Hercules muscled through Jean's TK while at a disadvantage underwater. He overpowered a maelstrom the false Terminus created that held the Avengers helpless with a Thunderclap. He's not an A-tier brick like Hulk or Doomsday but he doesn't have to be to beat Vader.
