Scott Pilgrim vs. The World Movie - In the movie Lynette Guycott is played by Tennessee Thomas. Her role is reduced to a background character. She is still the drummer for Clash at Demonhead and appears when the band plays, but the whole plot point with Lynette and Todd cheating together on Envy is taken out.
Scott Pilgrim vs. The World: The Game - Lynette appears as a mid-boss during World 3 alongside Envy Adams for the party. The pair take turns during the fight with Lynette using her bionic arm for quick punches, long range extendo punches, and by punching through the ground. Once they are defeated that triggers a cutscene where Lynette and Envy brawl (probably about Todd cheating on Envy with Lynette) and Lynette loses her bionic arm as she telports away. Envy then disappears with a cloud hanging over her head and leaves $2.60 for the player.
