of hypnosis to Superman and was detected by Batman and Wonder Woman. In this version, the name "Fortress of Solitude" was given by Professor Emil Hamilton in a sarcastically humorous remark while he visited the Fortress in one episode. In the future of Batman Beyond, a Starro from the Fortress' intergalactic zoo is revealed to have latched on to Superman years prior and subtly controlled his actions since then, including allowing an entire population of the creatures to breed in one of the aquatic chambers. The Justice League of the future travels to the Fortress where they are themselves taken over by Starros, until Batman is able to free Superman and the rest of the League from their control. The League then sends the Starro population through a boom tube back to the world where the original Starro came from. Legion of Super Heroes The Fortress also appears in the Legion of Super Heroes episode "Message in a Bottle". In that episode, the Legion chase Imperiex to the Fortress, where he shrinks himself to enter Kandor, to steal highly advanced ancient Kryptonian technology invented by Jor-El. Young Justice In the episode "Failsafe", the Fortress of Solitude appears on Robin's satellite imagery as a location that was being investigated by alien invaders, although this was merely a dream-like state for a training exercise gone horribly wrong. Eight years later, the Fortress makes the first appearance in the penultimate episode of its fourth season, "Over and Out", when a boom tube leads a time-traveling Kyrptonian criminal and his criminal parents, Ursa and General Zod, from the Phantom Zone. The Kryptonian criminals are amazed upon seeing what the sole survivor of their home world has managed to collect over four decades on their history and culture. It is in this icy and frigid fortress, Zod and Ursa begin to gain even greater abilities from Earth's yellow sun by resting in stasis pods. Justice League Action In Justice League Action episode "Field Trip", Superman gives Blue Beetle, Firestorm, and Stargirl a tour of the Fortress of Solitude. Live-action Adventures of Superman The 1950s Adventures of Superman TV series never mentions the Fortress of Solitude. The closest thing to it are cabins in remote mountains which Superman utilizes in the episodes "The Stolen Costume" (#13) and "Superman in Exile" (#33).
