Sean Wager is a close childhood of Volt and eight years older than Trent, making him 18 years old. Trent looked up to Sean as a cool big-brother figure when Trent was picked on. However, Sean was a bit of a troubled boy who struggled in his first semester at college. Despite his tough guy appearance, he was a smart student wanting to study genetics. His peers were jealous of him, that they pranked him by injecting him with an unstable sludge that completely rewritten Sean's DNA. He turned into a purple slime creature and dubbed himself Sewage. When he finished off the troubled students that did this to him, he slowly started to gain control of his slime powers and returned to his original appearance. Volt went to investigate the scene of the crime and confronted Sean since he was the only one who knew what happened. Shocked to find out Sewage was the one who did it, he had no choice but to take down his own idol and eventually won the battle.
