Exor

Exor is a giant sword-like character and a member of the Smithy Gang. Exor is actually composed of four parts, his Left Eye, his Right Eye, his mouth (which for some reason is named Neosquid), and the skull-shaped handle (named Exor) that controls the entire body. Exor is used as an inter-dimensional gateway between Marioâ€™s dimension, home of the Mushroom Kingdom, and Smithyâ€™s dimension, where Smithyâ€™s Factory is located. Consequently, Exor can transport an infinite number of troops and weapons for the Smithy Gang, as they are held in a separate dimension, not in an enclosed space.

Exor was a vital component of Smithyâ€™s invasion of the Mushroom World. Exor, on his descent to Bowserâ€™s Keep, shattered the Star Road, breaking off seven Star Pieces, thus eliminating the power of wishes from the world. Exor crashes into Bowserâ€™s Keep, sending Mario, Bowser, and Peach (who were battling in the castle) flying to other regions of the world. The keep is occupied by the Smithy Gang, and is used as Smithyâ€™s base of operations in the Mushroom World.

Mario returns to Bowserâ€™s Keep in an attempt to find Princess Toadstool. Instead, he finds a monstrously huge sword implanted in the castle. Exor claims the keep in the name of the Smithy Gang, and soon destroys the bridge linking Bowserâ€™s Keep to the rest of the world. Mario must find another way in.

Eventually, after collecting six Star Pieces, Mario returns to Bowserâ€™s Keep via a bus driver from Nimbus Land. After Mario defeats Boomer (on the chandeliers he fought Bowser on in the beginning of the game), Mario and his party are brought to the roof of the castle. Once there, Mario and his allies engage Exor. Although he wields impressive magical abilities, Exor is eventually defeated, but not destroyed. With his last ounce of strength, Exor opens his mouth, inhaling Mario and his party, transporting them to Smithyâ€™s dimension and his factory of weapons.

After Smithy is defeated, Exor dissolves into nothingness.

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

Many beginning players believe Exor is, in fact, Smithy. However, they soon learn the enormous Exor is only one of Smithyâ€™s servants.
