Persistence was a middleweight robot which competed in the final season of BattleBots. It was a white and blue wedge-shaped robot with no active weapon. Persistence was a rebuilt version of the team's previous entry from Season 3.0, Pink Slip, but did just as poorly, losing its first battle against Moebius. The only differences between Pink Slip and Persistence was the stripes now had a bigger gap in-between them, the name was on the front and the wheels now positioned at the back.
Persistence fought Moebius first, with Persistence running from Moebius when Moebius charged at Persistence. They continued this until there was just 30 seconds left on the clock. With just 30 seconds left of the fight, Persistence decided to confront Moebius, surviving until the end of the fight. Moebius, however, won by a 42-3 decision.
