Aremesh is a character in He-Man and the Masters of the Universe.
Aremesh is an armored Electroid, a robot made of pure energy, originating from Orko's dimension. He is powerful, intelligent, and confident to the point that he will stop at nothing to achieve his objective. Aremesh is near unstoppable, as no living being can touch him without their living force being drained. He travels upon a flying disk.
Aremesh suddenly appeared in the Royal Palace during a storm one day and subdued Man-At-Arms, Teela, and Prince Adam in order to capture Orko and acquire his "secret." He-Man chased him down and confronted him, but Skeletor had also been tracking Aremesh and transported both the robot and his captive to Snake Mountain. Aremesh agreed to help Skeletor conquer Eternia in exchange for his help getting Orko's secret, which turned out to be the Dimension Sphere. With some help from Man-At-Arms and the Sorceress, He-Man and Orko lured Aremesh to the Tar Swamp, where they opened a dimensional portal. Aremesh, however, could not be tricked into entering the portal, forcing He-Man to let Aremesh absorb his energy when he picked him up and threw him in.
