Shockirus (ショッキラス,   Shokkirasu) is a mutated sea louse kaiju created by Toho that first appeared in the 1984 Godzilla film, The Return of Godzilla.


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.


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


Heisei series

The Return of Godzilla

When Godzilla attacked the Yahata-Maru, Shockirus jumped off his body and came aboard the boat. Shockirus hunted down the crew members that had survived Godzilla's attack and killed them all, draining their bodily fluids and leaving behind desiccated husks. The last survivor, Hiroshi Okumura, was injured by Shockirus and locked himself inside a locker to hide from the creature. When reporter Goro Maki came aboard the ship the next day, he was attacked by Shockirus, who jumped onto his chest and crawled toward his throat. Fortunately, Okumura regained consciousness and stabbed Shockirus in the back with a hatchet, killing it.


Shockirus is an extraordinary jumper, and also can suck vital fluids out of a host. Its hard carapace also protects it from harm.
