The Monster was a large, formidable red scorpion that represented the last of four trials which led to the Genie's Lamp.
In 1934, the Adventure Society converged on Cairo, Egypt to unlock the Vault of the Genie, where the Genie's Lamp sat behind four large doors. The protegé of Society leader John Allen completed the tasks to unlock each door but through the fourth doorway, The Monster appeared to attack the group.
Allen's protegé used a device created by Zoey Hugo and Ken Sprocket to defeat the creature and claimed the lamp for the Society.
