This is a robot operated by Lord Crump of the X-Nauts. This robotic armor can fire its arms at an opponent and can cause great earthquakes. The X-Nauts built this as a weapon from their own technology. Crump used it to fight Mario in the Great Boggly Tree but lost the battle and it got destroyed. In Chapter 7 he used a newer version called Magnus von Grapple 2.0.
