Shockirus

Design Shockirus resembles marine arthropods like the horseshoe crab with its multiple legs and hard shell. Its shell has many bumps, and it has a two-pronged spike tail.

In the manga adaptation of The Return of Godzilla, the Shockirus look like ocean isopods but with facial features resembling cockroaches.

Origins According to Doctor Hayashida, Shockirus was likely a parasitic sea louse that fed on Godzilla's blood and was mutated by the radiation.
