The Iron-Masked Marauder operates as the primary antagonist in the fourth Pokémon film and an elite officer of Team Rocket under Giovanni. His mission to capture the Mythical Pokémon Celebi masks a deeper ambition: exploiting Celebi's time-travel abilities and dominion over nature to overthrow Giovanni, seize control of Team Rocket, and achieve global domination. Specialized technology defines his arsenal. Dark Balls—unique Poké Balls that override Trainer ownership—forcibly capture Pokémon, amplify their power to maximum potential, and corrupt their nature into aggressive compliance. He commands a four-legged spider-like mechanized vehicle with extendable electric shock claws and wields a functional jetpack for aerial pursuit. His Pokémon team, corrupted via Dark Balls, includes Scizor for combat using Double Team and Quick Attack, and Sneasel as a primary enforcer with Slash. He commandeers a poacher's Tyranitar, corrupting it to destroy the poacher's property via Hyper Beam. After capturing Celebi, he forces it to generate a colossal draconic wooden construct that attacks with vines, dark lightning, and a pink energy beam causing massive explosions. His methodology emerges through relentless actions: intimidating an elderly poacher (who once hunted Celebi) by corrupting the poacher's Tyranitar and demolishing his home, pursuing children protecting Celebi with his spider vehicle and Pokémon, wounding Celebi with electric claws before capturing it in a Dark Ball, and endangering children directly—including attempting to dislodge a protagonist midair during a jetpack chase. Celebi resists his control when triggered by pre-corruption memories, destabilizing his command. Exhibiting notable physical resilience, he survives Pikachu's direct Thunderbolt and a high-altitude fall through trees onto solid ground without losing consciousness. His plans unravel after Celebi's liberation collapses the wooden construct, plunging him into a lake. Stripped of Dark Balls and technology, he is immobilized by enraged forest Pokémon using String Shot at the lake shore, presumably leading to capture. The character's age, origin, birth name, activities beyond the film, background before elite Team Rocket status, and fate after capture remain unspecified.
