She is known for being evil, greedy, and manipulative. She is extremely loyal to give her son a heart-shaped picture with Madame Gasket on it.
Madame Gasket runs the Chop Shop: a massive factory where discarded mated and outmoded robots are collected, recycled, and recirculated. In order to increase her profits, she had her son Ratchet take control of Bigweld Industries, the world's sole provider of spare robot parts (for some odd reason) and have it instead distribute upgrades (for another odd reason, seems to be more profitable). Through this, she intended to render the city's lower-class population outmoded and (presumably) resell the resulting scrap metal to upgrade manufacturers. As a mother, she is very fond of (if not somewhat mean-spirited to) Ratchet.
Role in the film Edit
In the film's climax, in a battle with Rodney, Bigweld, and the others; she was about to order her armies of giant sweepers to attack the protagonists when Piper came to the rescue with all the outmodes that Rodney has fixed prior. During the battle, as Gasket's army is defeated, she tries to finish Bigweld off, but he is rescued by Rodney. Gasket then battles Wonderbot, but is overpowered and thrown into a slag pot, which then swings into the furnace. When the pot swings out, Madame Gasket is nowhere to be seen and has perished in the furnace, much to Ratchet's horror.
- It is unknown why or how she became evil or hated outmodes, especially since she herself is an outmode. It's possible that she was separated from the rest of the outmodes, making her jealous and evil.
- Although Ratchet drives the plot of the film, Madame Gasket turns out to be the true main villain because she had bigger plans, and is also revealed to be Ratchet's mother. She is also the true mastermind behind the film's primary threat, treated her son like an apprentice, used her slaves like puppets, and somewhat put Ratchet's father in chains (unseen).
- Her relationship with Ratchet is similar to the Fairy Godmother's relationship with Prince Charming in Shrek 2, as the mom is the main antagonist and the son is the secondary antagonist. Also, the mother dies, but the son survives.
