Thomas Malcolm "Tommy" Pickles is the main protagonist of the Nickelodeon animated television series Rugrats and its spin-off All Grown Up!. He is the older brother of Dil Pickles and the first son of Stu and Didi Pickles and the grandson of Lou Pickles and the nephew of Drew and Charlotte Pickles. He is clad in only a light blue t-shirt and a white diaper and is bald with blank, wide eyes. Tommy is the fearless, daring, adventurous leader of his three best friends, Chuckie Finster, Phil and Lil DeVille, and the cousin of Angelica Pickles, who is the main villain. He is the main character in all "Rugrats" movies except "Rugrats in Paris", where he only plays a supporting role. He is voiced by E.G. Daily, who also voiced Rudy Tabootie from ChalkZone, and Buttercup from The Powerpuff Girls. In the unaired pilot episode, he was voiced by Tami Holbrook.
Well, I guess we'll have to change his diapie.
