His roots go back to Mark Taylor, who designed He-Man, Skeletor and Castle Grayskull and worked on the line until about 1982: Battle Ram traces Megator to Taylor's art for an unrelated toy line about giants, with a ragged loincloth, spikes, a cloth wrap and manacles on chains. After Taylor left, Mark Jones traced that drawing and reworked it into an ogre, crediting Taylor's original in the corner, and Alan Tyler gave the giant a costume of his own, with a spiked ball chained to the wrist and a scimitar that was later cut. A near-final concept has a snake headband and a snake on the chest, both gone by the time the skull went on the toy.[3]
Ted Mayer was drawing along the same lines: his ogre concept dates from 1984, and his Big Foot concept had a spring-loaded leg like the one Megator ended up with. William George painted the front of the box, and an unknown artist painted the back; both show Megator fighting He-Ro, the young hero of the Preternia story. Errol McCarthy drew the same fight for a He-Ro cardback that never shipped, and Super7 finally printed it in 2019 with its replica He-Ro.
