The Ultimate Octobot is an enemy that appears in EarthBound in the Cave of the Past. It is similar in appearance to other Octobots save for its pink exterior. It generally has the same attacks as the Mechanical Octobot, albeit that they are much stronger. They are frequently encountered with a Nuclear Reactor Robot or a Wild 'N Wooly Shambler. As all members of the Octobot family do, it will try to steal items and fire beams in battle. It also can create a mystical electrical field that can paralyze a party member. Strangely, the clay model of the Ultimate Octobot is green but its sprite is pink.
