Editing Ebirah (section)

=== Role in ''Ebirah, Horror of the Deep'' (1966) ===
In his debut film, Ebirah functions as both a monster-of-the-sea and an unwilling guardian for the Red Bamboo. When a group of shipwrecked young men washes ashore on Letchi Island, they discover an enslaved population of Infant Island natives and a secret Red Bamboo weapons facility producing heavy water. To stop the Red Bamboo and free the captives, the group awakens a dormant Godzilla using a makeshift lightning rod.

Godzilla and Ebirah clash in a series of battles fought primarily at sea. The two kaiju engage in an iconic rock-throwing exchange, with Ebirah catching and hurling boulders back at Godzilla using his powerful claws. Ultimately, Godzilla overpowers the crustacean by ripping off both of Ebirah's claws, forcing the maimed monster to flee into the ocean. The Infant Island natives are subsequently rescued by Mothra.

The film was released in Japan on December 17, 1966, and was later localized in the United States under the title ''Godzilla vs. the Sea Monster'' (1968).
