Team Sonic Racing
In Team Sonic Racing, Donpa Motors was on the verge of a breakthrough with the development of a top secret project of theirs: the Ultimate Energy Engine. A machine powered by the inherent strength of teamwork, the Ultimate Energy Engine could revolutionize transportation, fuel new industries, and reduce pollution. For it to be finished though, they needed information on large amounts of Ultimate Team Energy. Wanting to produce the best with the aid of the bests, Dodon Pa invited the best racers he could find across time and space to compete in a team-based Grand Prix of his instead of relying on Donpa Motors' staff and resources, but kept his motives hidden to perserve the project's secrecy. He would then sent the information he gathered from the races' teamwork to his research and development, who would used it to work on the engine.

During the Grand Prix, the Ultimate Energy Engine was finished. Upon its completion, however, it was stolen by Dr. Eggman, who wanted to use it for his own nefarious purposes. Eventually, Sonic and his allies stopped Eggman, but the Ultimate Energy Engine was destroyed.
