Zanburonzo

Zanburonzo (ザンブロンゾ) - A trilobite monster. Its emblem, worn by the soldiers of the outpost that created it, is a trilobite. Not a modified human, but a modified Trilobite which received human blood and needed to absorb it to keep its new form. Able to switch between trilobite and Zanburonzo forms, remove parts of its shell to use as throwing weapons and spit acid. Defeated by Kamen Rider #2's Rider Kick, becoming a trilobite fossil again. Zanburonzo returned briefly in the monster army of the Kamen Rider vs. Shocker movie, but did not actually have an active participation there. Zanburonzo would reappear among the forces that ambushed Kamen Rider #1 in the movie Kamen Rider vs. Ambassador Hell. It was destroyed by Kamen Rider #1's Rider Punch.
