- "It there any way to defeat him?"
- — In-game description
R7038 (R•7038 in Mother) is a boss in EarthBound Beginnings, usually encountered between R7037 and R7038XX. The massive robot will be encountered if Ninten and co. stay at a healer's house on Mt. Itoi. After a cutscene in which Ninten and Ana confess their feelings and dance, Teddy walks in and tells them that there are loud noises coming from outside, which initiates a battle with R7038.
R7038 cannot be defeated, and battling it will certainly guarantee death for all party members. However, after the party is defeated, Lloyd will show up and destroy the robot with a tank (though he states that he missed) and rescues his friends. After the cutscene is over, Teddy is shown to be unable to help Ninten and his friends due to his injuries received during the battle, at which point Lloyd rejoins the party.
Though it seems necessary, this boss can be avoided entirely, simply by bringing Lloyd up the mountain before recruiting Teddy and obtaining Eve.
