Fortress of Solitude
The Fortress of Solitude is also a major setting for the "Justice League Unlimited" episode "For the Man Who Has Everything". A fight with the warlord Mongul took place there, after he delivered a parasite capable 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.
