Sauron is a supervillain from the Savage Land.
Sauron leads an army of dinosaurs with lasers against Hulk's team. When one dinosaur gets freed of Sauron's control, it befriends A-Bomb and helps defeating Sauron.
When Hulk faces Leader in the Negative Zone, the gamma villain reveals he was the one who provided Sauron with lasers.
- Despite being called a dinosaur, Sauron is not a dinosaur, but a Pterosaur, possibly related to a Pteranodon.
