Titano
Ironically, it was Superman himself who was responsible for Titano's return trip to Metropolis a year later. While using an alien time-viewer that he had discovered on another world, the Metropolis Marvel happened to be observing Titano's activities in the past when the device accidentally brought the ape back to the present. As before, Titano sought out Lois Lane and captured her, this time placing the reporter in a cage that he kept around his neck, and Superman was unable to get near the beast because of his deadly Kryptonite vision. However, while observing Titano being attracted to large round objects such as a giant balloon and the huge Daily Planet globe, Superman began to realize that the creature was actually foraging for giant coconuts that served as his main food source while in prehistoric times. Retrieving a supply of the coconuts from the past, Superman managed to pacify Titano long enough for him to rescue Lois and return the simian to the days of the dinosaurs (S No. 138/1, July 1960: "Titano the Super-Ape!"). Some time later, while journeying into the past in order to take accurate measurements of a prehistoric gigantosaur, Superman inadvertantly ran across Titano once again. Because he was weakened by exposure to the ape's K-vision, Superman had an unplanned encounter with a young Perry White and infamous mobster Al Capone in the 1920s during the Man of Might's attempt to return to the present (S No. 142/2, Jan. 1961: "Superman Meets Al Capone!").
Titano once fell into conflict with Krypto when the Dog of Steel journeyed into the prehistoric past to confront the giant ape after discovering that a bone he buried was crushed during Titano's last appearance in the present. Krypto began to play tricks on Titano, antagonizing the simian and starting a feud between the two animals. However, Krypto then decided to make peace with the ape, even going so far as to offer him bananas as his way of extending the olive branch. This gesture was apparently well-received by Titano, for he later helped save Krypto from capure by an alien spacecraft before the Super-Dog returned to the present (S No. 147/2, Aug. 1961: "Krypto Battles Titano!").
While still in the past, Titano was once observed by Bizarro during the Thing of Steel's quest to research famous monsters in Earth's history for a television program that he was planning to produce on the Bizarro World of Htrae. However, nobody on Htrae took Bizarro's stories of Titano seriously, choosing instead to believe that he was talking about King Kong (ADV No. 289/2, Oct. 1961: "Bizarro's Amazing Buddies!"). Bizarro would later go on to actually create a Bizarro-Titano as part of a ridiculous plan to dissuade Bizarro-Lois from pursuing a career as a wrestler. Just as the original Titano possesses Green Kryptonite vision, Bizarro-Titano had Blue K-vision (ADV No. 295/2, Apr. 1962: "The Kookie Super-Ape!").
Superman's pal Jimmy Olsen encountered Titano for the first time when a malfunctioning Superman Robot temporarily stranded him in a prehistoric valley that the ape was inhabiting (SPJO No. 59/1, Mar. 1962: "Stranded in Evolution Valley!"). When Titano reappeared in present-day Metropolis under unexplained circumstances, the ape once again reverted to his former habits, this time taking Lois' younger sister Lucy Lane captive while again keeping Superman at bay with his K-vision. Taking a special enlarging compound that enabled him to grow to gigantic proportions, Jimmy engaged the giant ape in battle and eventually managed to subdue him. An alien princess named Allura (who had originally come to Earth seeking Jimmy's hand in marriage) then took Titano with her to her planet of giants in the Ashtar star-system where the creature would find peace among apes his own size (SPJO No. 77/1, June 1964: "The Colossus of Metropolis!"). Some time later, Jimmy brought both Titano and the Flame Dragon of Krypton back to Earth using a special teleportation device devised by Professor Potter so they could battle each other for the filming of a new giant monster movie. However, the two incredibly powerful beasts ran wild during their combat ... with Titano disabling Superman with his K-vision ... forcing Jimmy to send the gigantic creatures back to where they belong (SPJO No. 84/1, Apr. 1965: "Jimmy Olsen's Monster Movie!").
Titano was briefly returned to Earth by Superman as a means of protecting his secret identity after exposure to an isotope of Red Kryptonite caused the Man of Tomorrow to grow to gigantic proportions and rampage through Metropolis in a reenactment of events found in the classic King Kong film. After ensuring that his secret was secure, Superman returned the giant ape to his home (S No. 226/1, May 1970: "When Superman Was King Kong!").
When last seen, Titano had been teleported back to Earth by the super-powered criminal called the Atomic Skull as a means of destroying Superman. Top that end, the villain had a sophisticated device implanted in Titano's skull that enabled him to control the huge simian via telepathic commands. However, when Superman rendered the Atomic Skull unconscious, Titano returned to his naturally docile behavior pattern, allowing the Man of Steel to devise a means to trap the gargantuan ape and return him to the planet of giants in the Ashtar system, where he continues to live to this day (S. No. 324, June 1978: "Beware the Eyes That Paralyze!").
