As Vegapunk's assistant, Stephen experienced transmigration to the One Piece world, where his alliance with the Revolutionary Army failed to defeat Imu. A second transmigration catapulted him into the Pokémon realm with his intellect intact—a consciousness spanning five centuries of advanced knowledge despite his youthful new body. Stephen now stands as: - Chief Pokémon Professor of the Pokémon League - Intellectual vanguard—five hundred years ahead of modern understanding - Executive Vice-Leader within Team Rocket's ranks - Master-level Trainer second to Professor Rowan alone - Rayquaza's acknowledged successor - Honorary Chairman of the Alola League - Supreme Dark Pokémon Commander
