Kanibubbler

Kanibubbler appeared in 1971 TV series called Kamen Rider. Kanibubbler (カニバブラー Kanibaburā) is a crab monster. He can attack with a large claw on his left hand and release bubbles from his mouth that melt human beings upon contact. His soldiers have machine guns that shoot similar projectiles. His personal emblem, worn on his soldiers' masks, is a crab. Kanibubbler attacked various locations around Japan, but Kamen Rider #2 eventually tracked his underwater base and faced him head on. After his bubble attack failed, He was destroyed by Kamen Rider #2's Rider Punch.

Kanibubbler was resurrected later, episode 37, participating in an operation to kidnap children and test a poisonous gas on them, coordinated by Colonel Zol. However, Kazuya Taki saved the kids and released the poisonous gas on Kanibubbler and his companions, destroying them.

Kanibubbler also made a brief return appearance in the monster army of the Kamen Rider vs. Shocker movie, but did not actually have an active participation there.
