Sweet Tooth is a fictional character from the Twisted Metal video game series. Although he's universally known as Sweet Tooth, the character's real name is Needles Kane, and he is often depicted as the split personality of fellow character Marcus Kane. Sweet Tooth is designed around the premise of a killer clown that drives a combat ice cream truck, and his face has been featured on the cover of every Twisted Metal game with the exception of Twisted Metal 2, making him the series' mascot. While being in every title of the series, he has not always been immediately available, requiring to be unlocked in some. He is the only character (besides Marcus Kane) to drive more than one vehicle in any of the games, being the driver of Head-On's Dark Tooth, Tower Tooth, and as of Twisted Metal: Lost, Gold Tooth. Sweet Tooth has the most relationships to any group of characters in the entire series: his father Charlie Kane (driver of Yellow Jacket in the first game) and Marcus Kane (split personality, Roadkill's driver). The final level of the second game features a boss fight with his father as Dark Tooth. Spectre's ending in the first game strongly hints that Sweet Tooth was the serial killer who killed the driver of Spectre five years before the competition. He has an unnamed brother that only appeared in Twisted Metal: Black, who drove that game's Yellow Jacket vehicle. He is also directly responsible for the creation of that game's Axel, whose wife he killed, and Cage, who wishes to be a greater killer than Sweet Tooth. The character has gone through several redesigns differing from game to game, similar to fellow character Calypso, and his personality has grown progressively darker along the way. Despite the changes some factors remained uniform, notably the perpetual flame on his head introduced in the second game. Starting with Twisted Metal: Black, his design became a large, somewhat overweight bare chested clown with a flaming mask locked into a permanent maniacal smile. Head-On expanded on this idea, changing the mask to face paint and the smile to his own. Design and history Sweet Tooth's original look featured him as a green-haired, slim simple circus clown who had escaped from a mental institution. The design was expanded upon in the second game in response to changes to the truck's design, notably due to the clown head
