Leanne "Le Le" Platter (voiced by Pamela Adlon) — Leanne is Luanne's violent alcoholic mother and Hoyt Platter's ex-wife, who was imprisoned for stabbing her husband in the back with a fork. Though she is often mentioned during the series, She appears only in the episode "Leanne's Saga," visiting Luanne in Arlen after her release from prison. She often calls Luanne "Lu-lu" and notes how people mistake her and Luanne for sisters whenever they are seen together. Leanne is also physically fit and, while staying with Hills, did a daily workout by lifting a shovel that held two full buckets of water.
During her appearance, Leanne is 34 years old, as she stated while drunk at her engagement party. According to Hank, Peggy's brother Hoyt had planned to marry a pharmacist, but wound up marrying Leanne instead after she entertained at his bachelor party. After being released from prison, Peggy reluctantly lets her stay at the Hill house until she can find a job that can support her.
While at the Hill house, Leanne meets Bill and the two start a relationship. While seeing Bill, she persuades him to buy things for her and Bill winds up with no cash-on-hand until he can receive his paycheck. Bill is soon unable to pay for a renewed prescription for the medication he needs to treat his foot fungus. When Leanne notices that his foot fungus has returned, she violates her court order and starts to drink again. She and Bill are soon engaged, though their relationship rapidly degenerates once she starts drinking again and starts violently abusing Bill. Everyone, except initially Bill and Luanne, sees her as an un-ladylike, psychotic menace to society. During Bill and Leanne's wedding reception, Leanne is heavily drunk and does exotic dancing. After Buckley refuses her advances, Leanne grabs a fork and tries to stab him. Peggy prevents Leanne from doing.
Leanne then lies to everyone by saying she is sorry and, reverting to her feral state. Leanne was screaming to and runs over and attacks Peggy, falling down on the ground. However Peggy is able to fend off Leanne with her big feet. After Peggy defeats Leanne, Leanne decides to leave and asks Luanne to come with her. Luanne, however, shakes her head, and Leanne, still drunk, shouts, "Fine! Then, I ain't your sister no more!" Leanne then steals Bill's truck and drives out of Arlen, presumably for good. In "Fun with Jane and Jane" where Luanne joins a cult she thinks is a sorority, she mentions her mother being in prison, which infers Leanne got thrown back behind bars for reverting to her previous ways. However, she can be seen at Luanne and Lucky's wedding, meaning she was either released or was allowed to attend Luanne's wedding before going back.
She appeared in a flashback of Hank and Peggy's wedding video, in "Hank's Cowboy Movie".
- Lucky's Wedding Suit (non-speaking)
- Life: A Loser's Manual (mentioned)
- It is revealed in "The Company Man" that Leanne may have remarried and Peggy was one of her bridesmaids, which is strange given that Leanne and Peggy hate each other.
