Old Robot (オールドロボット) are the ancient battle robot bodies that the Pararoid S-38s possesses in Morph Moth's stage, serving as mid-bosses. They have limited mobility due to the fact they are junk, but a Pararoid S-38 can use them to jump and occasionally pounce on X from different heights and speeds. They will sometimes fire aimed "shots" of junk. The Old Robots can only be damaged by hitting their exposed cores in midsections, causing them to gradually fall apart until a Pararoid S-38 abandons it. Taking too long to defeat the S-38s however will allow them to burrow and retrieve another Old Robot from the junk pile. A single Silk Shot hit will eliminate the Old Robot.
