Sonic Racer

S1, E6: Sonic is hired into an obvious trap when a frustrated Robotnik decides to appeal to the Hedgehog's ego and announces a "race to determine the fastest on Mobius'. Sonic decides to join the race despite Sally's objections that she needs him on a mission to take out Robotnik's power generators. The Freedom Fighters decide to launch this mission on the day of the big race, figuring Robotnik will be too pre-occupied. The race turns out to be much tougher than Sonic expected when he sees his competition a sleek, four-legged robot called the Speed Bot, who is not only out to beat Sonic, but capture him as well.
