Sergei Petrov

Spencer, known as Sergei in the Japanese version, is a towering presence on the battlefield. At 16 in Season 1 and 18 in Season 3, he’s a quiet powerhouse with a fierce competitive spirit that shines through when he’s in the ring. Trained in the Abbey alongside the Demolition Boys, he’s the only blader strong enough to control his bit-beast, Seaborg. Although he works to impress Boris, he often finds himself falling short. Loyalty runs deep for Spencer, especially towards his team, the Blitzkrieg Boys, and he shares their disdain for Boris and skepticism of Kai. When he finally speaks, it’s always impactful. In G-Revolution, he rolls out with an upgraded Seaborg 2, boasting some serious moves like the Stramolyu attack!
