* Buck, Tara's only male personality. He is a loud and profane troublemaker, characterized by Collette as "the aggressive protector type, a man's man".[2] Buck has a gun named Persephone and often goes to the shooting range with Max and Marshall. He explains his lack of a penis by claiming that it was shot off in Vietnam.[4] Collete said that Buck is her favourite of the three personalities "just because he's most challenging", though she has to "always be careful not to make him a stereotype."[2] Unlike her true identity and other alter egos, he is left handed. He is a heavy drinker and smoker. He wears large glasses and a trucker hat, unlike the other alters.
* Alice, Tara's "June Cleaver-esque"[2] housewife personality. Alice often bakes for the family and labels herself as old-fashioned.
* T, Tara's wild, pot-smoking 15 year old personality. She is hypersexual and she wears thong underwear and low cut shirts. She relates well with Kate, providing her with birth control medication and attempting to take her on a shopping spree with Tara's credit cards. She often tries to seduce Max, but he refuses to have sex with her because she is not Tara and Tara would be upset if he slept with one of her alters.
