Hulk was a pro football player, a guy who loved nothing more than clutching a pigskin and barreling through the defense like a runaway freight train. He lived for the gridiron. But he never, in his wildest dreams, imagined he’d see a pair of nipples bigger than a football. He became a giant baby, reborn with a new name: Orion. Orion was the runt of the giant litter, the weakest of the bunch. But when he turned ten, something crazy happened. He saw a strange panel – that not only displayed his stats but also helped him level up. With the panel’s help, and a whole lot of elbow grease, Orion led his giant tribe to become the most powerful in the Barren Mountains. He went from zero to hero, becoming a mighty Titan King. He was no longer the runt; he was the top dog.
