Fullback represented one of the six distinct roles within the game of grav-ball. In each grav-ball match, every team utilized a pair of fullbacks. Their responsibility involved positioning themselves on either side of the center striker, accompanied by two strikers positioned further towards the "wing" areas. Typically, a fullback's primary function was ball advancement, while the strikers specialized in quick movements to receive passes.
During his tenure at the Junior Academy of Applied Sciences, Beck Ollet was selected to play fullback for the AppSci SaberCats. He maintained a close friendship with Zare Leonis, the team's center striker; however, he occasionally displayed a tendency toward impetuousness.
