Exor

Exor appeared in 1996 video game called Super Mario RPG: Legend of the Seven Stars. Exor is a massive sword-like member of the Smithy Gang and a major antagonist in Super Mario RPG: Legend of the Seven Stars. Exor is actually composed of four parts: the Left Eye, the Right Eye, the Mouth (which is inexplicably translated Neosquid), and the skull-shaped pommel (named Exor) that controls the entire body. Exor is used as an inter-dimensional gateway between Mario's dimension, home of the Mushroom Kingdom, and Smithy's dimension, where Smithy's Factory is located.

The iconic and recurring image of Super Mario RPG: Legend of the Seven Stars is Exor embedded in Bowser's Keep.
