Override Prime (オーバーライド・プライム, Ōbāraido Puraimu) is the best racer on Velocitron, and as such is the leader of the planet. She seemingly embodies the culture itself; she is quick-witted, decisive, self-sure and always looking for a challenge. This has its upsides and downsides: while she's brave and determined with a never-give-up attitude, she can also be cocky to the point of arrogant, if not selfish and shortsighted. She entered the great race for leadership of a Prime by lying about her gender and posing as a male, and has been defending her title and proving herself more than a match for anyone since.
After contact with the Autobots from Cybertron, particularly Hot Shot, Bumblebee, Blurr, and Optimus Prime, she has matured into a more careful, more compassionate robot, less focused on being the best racer and more focused on being the best leader for her people... though she still maintains her never-lose attitude and love of high-speed challenges.
She has developed a close bond with the human girl Lori, referring to her as "Little Sister", which Lori reciprocates by calling Override Prime "Big Sister".
Long-time champion and leader of the Speed Planet, Override Prime is always ready for a race. Acceleration is her only ideal, but she respects anyone with the guts to challenge her. She's faced and beaten thousands of upstart speedsters in her time. Though at first suspicious of the intentions Hot Shot and the Autobots have for her world's Cyber Planet Key and a war for the greatest prize, Override is only too glad to help once she realizes what's at stake.
Her veichle mode is a Velocitronian Lotus car.
