Looker

Looker investigates Team Galactic during Platinum. His presence is one of the game’s notable additions to the original Sinnoh storyline, providing an outside perspective on the organisation’s activities.

• Story: He appears at several points around Galactic activity, following leads while the player performs much of the direct exploration and battling. His appearances should not be transplanted unchanged into Diamond and Pearl guides.
• In the game: Treat him as a story contact who helps frame the investigation. He does not replace the need for keys, field moves or specific story milestones when a Galactic facility remains inaccessible.
