–NOTE: In World’s Finest Comics #107 we learn that Batman and Robin go on “many” unspecified time traveling trips that are never shown in the comics, presumably in the latter half of Year One (1967) and throughout Year Two (1968). We simply have to imagine other time-trips listed in this section of the website. Of course, there may have been unspecified trips to the future in 1967-1968 too, but for simplicity’s sake, I’m imagining only backward treks.
–Circa 200,000 BCE. Future site of Metropolis.
World’s Finest Comics #151. 1972 Batman, evolved into an evil super-brained jerk by a Kryptonian “accelerator” machine, has left his home-time and gone to live in the 8,018th century. A devolved Superman goes to the 8,018th century, grabs Batman and flies him to the Pleistocene Era. Plagued by mammoths and sabertooth tigers, Batman pleads for help. With his superior intellect, Batman instructs cave-Superman on how to squeeze materials into metal, which the Dark Knight then fashions into an exact copy of the “accelerator.” The evil Batman attempts to further devolve Superman, but Krypto—having traveled through time from 1972 to find his master—arrives and pushes the machine’s ray into Batman’s path, returning him to normal but devolving Krypto. Batman uses the machine to fix everyone. Superman then smashes the machine and flies everyone back home to 1972.
–48,029 BCE. North America.
World’s Finest Comics #138. From 1971, Batman and Robin chase evil aliens way back to 48,029 BCE using the Carter Nichols method. Superman joins the Dynamic Duo in the distant past where they discover that the aliens have abducted a bunch of early humans. Batman, Superman, and Robin then disguise themselves—terribly, I might add. Batman and Robin tear their costumes to shreds and Batman puts on a fake beards made of animal fur while the Boy Wonder gives himself a mullet. Superman, for some unknown reason, actually carries a tattered Superman costume (since his is virtually indestructible) and dons it, also wearing an awful beard. Soon, our heroes learn that the aliens’ ray beams are used for mind-control, but only function on primitive minds, hence their attack upon Prehistoric mankind. Batman, Superman, and Robin play as though they’ve been controlled and are taken in a spaceship back to 1971 to the alien home world to be slaves. After defeating the bad aliens and turning them over to the good alien government authorities, Batman, Superman, and Robin fill a spaceship with the human captives and return them to 48,029 BCE. The trio then returns to 1971 Gotham via Nichols’ time-box return button.
–26th century BCE. Giza, Egypt.
Detective Comics #295. In 1970, Batman and Robin fight giant monsters and then jaunt back to ancient Egypt (post stone construction era, but prior to the completion of the Giza Necropolis), via the Carter Nichols method, to clear up the mystery of a ancient mural depicting them in action. In Ancient Egypt, Batman is instantly taken captive by time-traveling aliens from Nakor, who have already captured a local soldier Khau-Re. The Nakorians explain that they sent the two beasts to 1970 to test Batman, and then they show video of the battle to Khau-Re. Robin then frees Batman and Khau-Re, and in the process, learns that the aliens can’t see the color red. After meeting the pharaoh, Batman and Robin paint themselves red and defeat the aliens, sending them running and convincing them never to attempt an invasion of Earth again. Red Batman and red Robin then return to 1970 with an explanation for Nichols.
–336 BCE. The Mediterranean and Egypt.
World’s Finest Comics #107. In 1970, a giant alien fire monster that has been dormant and hidden on a small Mediterranean island for 2000 years, comes to life, prompting Batman to seek a long lost alien weapon to defeat the creature. Batman and Robin visit Professor Carter Nichols, who sends the Dynamic Duo back to 336 BCE when the weapon was delivered to Earth but subsequently lost. In 336 BCE, our heroes learn that a merchant sailor named Sethy took the weapon from the Mediterranean to Egypt as a gift for Pharaoh Khababash. Batman and Robin make it to Egypt, steal the weapon from the Pharaoh, and bury it inside one of the Great Pyramids. Then they attempt to go back to 1970 via their return-button time box belts—(a new addition to Professor Nichol’s time-traveling method)—but the boxes are broken, trapping them in the past. A safeguard on the boxes activates an alert in Professor Nichols’ lab, which allows him (from 1970) to view their actions in 336 BCE. Nichols calls Superman, who then uses his unbelievable speed-powers to break the time-barrier and rescue his friends. In Egypt, Superman fixes the time boxes, forming a “time-field” that takes the trio back home to 1970 where they defeat the monster.
–circa late 5th century CE. Britain.
World’s Finest Comics #162. An alien (disguised as Sir Lancelot) forces Batman and Superman to time-travel from 1973 to Medieval England, where they heroes find themselves standing before a bunch of aliens in disguise as King Arthur, Sir Gawain, Sir Kay, Sir Bohart, and Merlin. “Arthur” explains that alien doppelgängers expelled the Knights of the Round Table from Camelot and, in desperation, Merlin was able to send Lancelot to retrieve the “greatest heroes of all time” for assistance. In actuality, the aliens have failed to capture Camelot and are tricking Batman and Superman into helping them do it now. Batman, Superman, and the evil aliens storm the castle gates and defeat Arthur and his knights. Later, fake Arthur slips up, revealing himself as an alien. Batman and Superman switch sides to fight alongside the real Arthur, Merlin, Lancelot, Gawain, Kay, Bohart, Bors, and Galahad. The aliens pack back into their UFO and Superman hurls it into deep space. Arthur knights Batman and Superman before they return to their 1973, presumably via Merlin’s magick.
–March 6, 522 CE. Norseland (Scandinavia).
World’s Finest Comics #135. In 1971, Batman and Robin visit Carter Nichols and jaunt to Norseland circa 522 CE in search of time-traveling criminal Rak Durr. In Norseland, the Dynamic Duo are captured by vikings that have been tricked into allying themselves with Durr. The Norse god Thor (or someone pretending to be Thor, as Batman oddly assumes despite having met the real Thor before) then demonstrates the power of his mighty hammer Mjölnir, which Durr steals before returning to 1971! Batman notes that Mjölnir’s power comes from a meteor before then activating his time-return button and scooting back to 1971 with Robin.
–1479 CE. Florence, Italy.
World’s Finest Comics #132. In 1971, crooks Denny Kale and Shorty Biggs best Batman and Robin, learning their secret IDs in the process, before time-traveling to 1479 Florence, Italy. After Superman is captured by Kale and Biggs in 1479 Florence, Batman and Robin rush to Professor Nichols’ lab and time-travel to the past to make a rescue. In 1479, the Dynamic Duo chases after the Kale and Bigs, who are dressed as a fake Dynamic Duo and have allied themselves with a bunch of bandits led by an alchemist. After rescuing Superman, Batman and Robin fight the baddies, causing a chemical spill that erases Kale and Biggs’ memories (including knowledge of any secret IDs). Using the “time box return,” everyone goes back to 1971.
–1880 CE. Plain City, Utah, USA.
Batman #99, Part 2. In 1968, reporter Jack Farr finds an old half-torn newspaper clipping that shows a picture of Batman and has a headline that reads “Gila Bill, Wanted Outlaw, Shot and Killed by Town Marshal Bat Ma—”. Farr accuses Batman of having been a gun-toting marshal out West before appearing in Gotham. Thus, Carter Nichols sends Bruce and Dick back to the Wild West. In Plain City, Batman and Robin take down bandit Pecos Pete, which earns Batman the job of interim Town Marshal. After Pete escapes, Batman disguises himself as Pete to flush out his boss, Gila Bill. Batman, in his Bat-Stagecoach, chases down Gila Bill, who is then gunned down by new state-appointed Marshal Bat Masterson. The headline makes sense now and Bruce brings a complete copy back to 1968 with him.
