Sweet Tooth proved to be an extremely skilled competitor, taking out many opponents, but it soon lost its appeal. He realized that Calypso was just using him as a pawn to collect souls and become stronger. Thus when Sweet Tooth won the tournament, he used his wish to take Calypso's place as organizer of Twisted Metal. He was now the ringmaster instead of the clown, running things from his carnival like lair with his horde of clown minions.

However Sweet Tooth was cursed by a preacher, which caused his head to be engulfed in flame, and he broke out of the chair, killing three police officers in a pain induced frenzy. Sweet Tooth eventually ended up in an asylum, where the curse caused him continuous pain that grew everyday. However Calypso showed up, offering Sweet Tooth a place in the Twisted Metal tournament. If he won, then Calypso would show the clown how to undo the curse and Sweet Tooth agreed to compete. In his ending, Sweet Tooth went to Calypso to claim his prize and he gave the clown a vial containing the blood of the preacher who cursed him. Calypso told him if he drank it, the curse would be removed, but if he went back to his killing ways, the curse would come back. It took Sweet Tooth only a few seconds to decide that he’d rather be cursed than give up his life as a killer. He smashed the vial and killed Calypso, resolving to be the greatest killer of all time.

In his ending, Sweet Tooth crashed into Calypso’s lair and he asked the clown what his wish was. Sweet Tooth said he’d been getting tired of his face and noted how they’d be going through the same thing year after year. He then made his wish, that he and Calypso would change places. Calypso said he would never grant such a wish, but Sweet Tooth pointed out that he had no choice. The two suddenly morphed into each other and Calypso tried to order his guards to kill Sweet Tooth, but he had them kill Calypso instead.

Sweet Tooth eventually pursued her to a hospital, where he wiped out numerous patients, doctors, and police officers in his search for her.

Finally, he headed back to Sunsprings for his final challenge, where he faced off against Mr. Grimm and his gang, who were using a pair of giant monster trucks. Sweet Tooth managed to take one down, prompting Mr. Grimm to activate a powerful suit of armor on the other, making it invincible to attacks. However Sweet Tooth’s gunner had him get under the truck, allowing him to get under it and plant some C4. But when the gunner asked him to come back and pick him up, Sweet Tooth just detonated the C4 anyways, killing his gunner and destroying the armor, before he took down the last truck.

However she had killed herself before Sweet Tooth attacked the hospital, thus Calypso teleported him into her coffin, burying him alive.

His son headed to the grave and dug it up, taking his father’s mask and lighting his head on fire, before racing off in Sweet Tooth’s ice cream truck to kill Calypso and avenge his father.
