A peaceful world where all living creatures are robbed of their free will and have no need to think.... This is Psychi's ideal. Gai and Juggler shake with indignation, for they see a life with no will as a living hell.

As part of Queen Bezelve's trap to use Queen Amate's emotions against her, the War Deity is racked by a will-robbing venom! Ultraman Orb attempts to defend her, but he too falls to the poison!

In a last-ditch effort to rule the universe, Psychi merges with Queen Bezelve to become the terrifying Giant Monster Psyqueen. Ultraman Dyna and Cosmos rush to aid in the fight against this massive enemy, and a battle for the fate of the universe begins!
