Exor

Exor is a major antagonist in Super Mario RPG: Legend of the Seven Stars. Exor is in charge of being the gateway between Mushroom Kingdom and Smithy Factory.

Biography
Exor first appeared descending to Bowser's Castle when he destroyed the Star Road and thus spreading the seven stars. This causes that the wishes from the world cannot be done, while Exor settles on Bowser's Castle causing a great crash. This crash also sends Mario, Peach and Bowser away. Then Smithy Gang take over Bowser's Castle as their main base on Mushroom Kingdom.

Exor is later seen when Mario returns to Bowser's Castle just to learn from Exor that Bowser's Castle now belongs to the Smithy Gang and destroys the bridge to prevent anyone to return in while Mario escapes from the place in time. Once Mario gets six stars, he and his party will return to Bowser's Castle in a bus driver from Nimbus Land. When they reach to the roof, they will confront Exor in a battle which Exor loses. Exor then transports them into the Smithy's Dimension where the Smithy Factory is on.

When Smithy and his gang are finally defeated, Exor dissolves, disappearing from Bowser's Castle.
