The original Tommy Turbo fought for the allies in World War 2, using his speed to fight alongside other heroes such as the original American Dream in the fight against the Axis. Tommy Turbo was a hero in every sense of the world.
The current Tommy Turbo shares none of his great grandfather’s heroic sensibilities and is only interested in number one. He uses his speed to steal from whoever he wants. He has become a recurring foe of the current American Dream and her partner, Sentinel.
He also reserves a special hatred for Adrenaline. The showboat millionaire playboy has all the things Turbo thinks he deserves. It doesn’t help that Adrenaline frequently refers to him as a wannabe and always outraces him.
