Smashopper was a giant metallic grasshopper-type Invectid machine that battled Hunter Steele upon his arrival in the Inner World while an unnamed Invectid Commander rode atop him. Initially Smashopper was able to overpower Battle Spider Shadow, but was quickly defeated once Hunter and Shadow transformed with the power of Hunter's Manacle. While the commander called Smashopper his "pet", Smashopper appears to have been more of a non-sentient machine. Likely meaning that Smashopper was some variety of Battle Beetle.
