One of the boss characters in Super Mario RPG.
It has the shape of a huge sword, with googly eyes like Sanpaku eyes on the handle and canine teeth protruding from its mouth. He boasts the largest body size among the boss characters in this game. His appearance is quick, and during the showdown between Bowser and Mario, who kidnapped Princess Peach as usual in the prologue of this game, he suddenly falls from the sky towards Bowser's Castle, and the impact blows Mario out of the castle. In the end, they destroyed the bridge at the entrance to the castle and completely occupied Bowser's Castle. Moreover, when it attacked from the sky, it destroyed Star-Lord, and the shattered pieces became star pieces that fell all over Mario World. For this reason, he is the beginning of all the disasters in this work. The final battle with Calibur comes at the end, when Bowser's castle is revisited. They searched every corner of the world, but through a process of elimination, they came to the conclusion that the last one of the seven star pieces could only be found here. At the arrangement of the King of the Marshmallow Kingdom, Jugem drove a cloud bus called Jugemu. We ask them to send out a bus, and we confront them again when they re-enter from the sky. His true identity is the gatekeeper and the entrance to the Weapon World, which is the home base of the Kajioh Corps. The inside of Calibur's mouth is the entrance to the final dungeon, the weapon world. For this reason, it is essentially considered to be a vehicle with a will, similar to Onoforce.
