R•7037 (spelled R7037 in the English prototype) is a robot in Mother that Ninten's party encounters in the Advent Desert. It's an optional boss that guards the way to the Ruins of Desert. Under normal circumstances, it can, and will, kill a party member in one hit. However, before it is fought, Ninten and friends can gain access to a tank, which can deflect R•7037's attacks and is the only practical way to defeat it. After you defeat it, the tank breaks and can no longer be used. Upgraded versions called R•7038 and R•7038XX also appear in the game.
