Gigantus is a giant Rock Golem introduced in Skylanders: Giants. He appeared 10,000 years ago during the Time of the Giants, helping the Giants learn what they can do, such as picking and throwing boulders, and jumping down to smash through holes.
- His name is often mistaken as 'Giganticus', which is in the name of one of Wham-Shell's upgrades.
- He was originally going to be the Life Giant, but he was scrapped in favor of Tree Rex.
- After he had jumped into the mine shaft, he was never seen again in the entire series. It is unknown what happened to him.
