The Final Starman is an enemy in EarthBound. They are the strongest type of Starmen of Giygas's army next to the Starman Deluxes and can only be encountered in the Cave of the Past. The Final Starman's initial status is PSI Shield β, rendering PSI moves useless against it until the shield is dispersed. They can use Brainshock Ω, PSI Healing Ω, PK Starstorm α and Ω, Shield β, or flash a menacing smile to waste a turn. Final Starmen can be battled with a Ghost of Starman, a Nuclear Reactor Robot, or both. Their in-game sprite depicts them golden with pinkish tint.

Final Starmen serve as the successors of the Last Starmen in EarthBound Beginnings, as both are gold-colored Starmen, are the strongest of their kind, and appear in the game's final area.

The Final Starman appears on the boxart of EarthBound. The boxart represents a battle between Ness and the Final Starman, depicting a surreal swirl of color behind it and Ness's reflection in the Final Starman's visor. However, the scene depicted is not possible during the regular course of the game, as the souls of Ness and co. are actually in robotic bodies while they are in the Cave of the Past, assuming that the reflection is not actually depicting the Devil's Machine because no Starmen are actually seen alongside Giygas in the game.
