Mirror Team Rocket showed up in The Cave of Mirrors as one-off characters. They're basically the Mirror World versions of Team Rocket—so naturally, they're the complete opposite. While the regular trio are scheming villains, their mirror counterparts are actually heroes who go around fighting criminals and bad guys.
The most noticeable difference is how they sound. They've all got distinctly deeper voices compared to their normal selves, which makes them feel genuinely different despite being the same characters. Even their uniforms reflect this flip: the "R" on their chest is horizontally mirrored instead of normal.
