Meowth, known as Miaouss in French, appears in *Pokémon 4Ever* alongside Jessie and James as part of the recurring Team Rocket trio. This Meowth retains his unique ability to speak human language, a skill he self-taught to impress a female Meowth named Meowzie. This effort led to his rejection by Meowzie and other Meowth, who perceived him as unnatural, motivating his decision to join Team Rocket.
Within the film, Meowth assists Jessie and James in their comedic antagonistic role, primarily targeting Pikachu. Initially cooperating with the primary antagonist, the Iron Masked Marauder, due to fear of his ruthlessness, Meowth and his teammates later display visible horror at the Marauder's methods. They react strongly to witnessing his capture of Celebi through brutal electrocution and the use of a "Dark Ball" that corrupts the Pokémon, turning it evil and amplifying its destructive power. This reaction underscores that while Meowth engages in Pokémon theft, he and his partners explicitly refuse to condone sadistic torture or manipulation of Pokémon.
Meowth also demonstrates allegiance to Team Rocket's existing hierarchy. Jessie's shock upon learning the Marauder plans to overthrow Giovanni and seize control highlights the trio's underlying loyalty to their boss. Following the Marauder's defeat and Celebi's rescue, Meowth and his teammates completely abandon their pursuit of Pikachu for the remainder of the story. They are last seen relaxing peacefully near the Lake of Life, a departure from their usual persistent antagonism.
