In other media Television Brainiac 5 made a non-voiced cameo appearance in Superman: The Animated Series. In the episode "New Kids In Town", he chats with teammate Triplicate Girl. At the time of his debut it was unclear if he, in fact, used his given name or had any connections to Brainiac. However, his costume included a chest symbol comprising three circles forming an inverted triangle. This closely resembled the discs on the animated Brainiac's forehead (and his icon when he was a computer program), suggesting some kind of connection between them. It was revealed on commentary on the Superman: The Animated Series Vol. 3 DVD box set that this character was in fact Brainiac 5. Brainiac 5 appears in Justice League Unlimited, voiced by Matt Czuchry. Like his comic book counterpart, Brainiac 5 wears his trademark force field belt, which protects him from the Fatal Five's attack. It is revealed that Brainiac learned to pass its code biologically and created Brainiac 5 as an organic being. Unfortunately for Brainiac, Brainiac 5 rejected evil and joined the Legion of Super Heroes. In the episode "Far From Home," he brings Green Arrow, Supergirl, and Green Lantern into the future to help him battle the Fatal Five. In the short time after meeting each other, Brainiac 5 and Supergirl fall in love. After the Fatal Five are defeated, Supergirl chooses to remain in the future with him and the Legion.  Brainiac 5 appears in Legion of Super Heroes, voiced by Adam Wylie. He is a core member of the Legion of Super Heroes. This version is Coluan, a nano-based cybernetic organism that not only possesses 12th-level intelligence, but can assume a human-like form. His human-like form can also alter its shape to create tools and weapons or transform into a large, battle robot form, much like the reboot Legion member, Gear. His AI core is based on the original Brainiac 1.0 from whom he tries to distance himself as best as possible. Unlike many versions where he is portrayed as cold and unfeeling, this version is considerably more emotional. In the first season, he often appears eager to prove himself to his older teammates, particularly the original Superman; Brainiac 5, unlike his villainous ancestor, idolizes Superman. However, his high intellect and his emotional nature often cause him internal conflict; for example, he idolizes Superman, but knows intellectually that he cannot reveal many of the things he knows lie in the future for Superman once he is returned to his own time, as Superman's knowledge of his future events could change what is, for the Legion, history. In the second-season episodes "Chained Lightning" and "Message in a Bottle," Brainiac 5 grows close to Shrinking Violet; however, as the series ended it remains unknown if this was an intended romance or not. He seems to have feelings for Superman himself, because of the simulation he produced that involved him and Superman shown at the premiere of season two and many other incidents in the series. In the second-season premiere, Superman X (a clone of Superman from the 41st century) hints that someday Brainiac 5 will be responsible for something terrible in the future. The starting phase occurs in "Message in a Bottle," when Brainiac 5 was forced to tap into the data of Brainiac who had been observing Brainiac 5 since he came online. Brainiac 5 travels within himself to meet with his ancestor, where he is offered data from the original Brainiac. Brainiac 5 forcefully accepts the "gift" of data he needed to stop Imperiex from his ancestor who hinted it to "open new avenues of possibilities." Soon after using the info he obtained to save Kandor and restore it to original size, Brainiac 5 begins to suffer data corruption as Imperiex intended from the start, becoming cold and unfeeling in the process. Once completely under his ancestor's influence during the "Dark Victory" series finale, Brainiac 5 assumes a new form in homage to his ancestor and leaves the Legion to join Imperiex's army, taking command after killing Imperiex. Once overpowering the hivemind on his homeworld of Colu with his will, Brainiac 5 intends to bring "order" to the universe, destroying any who interfere. Thanks to Superman and Superman X, Brainiac 5 managed to regain control over himself and overpower his ancestor. In the process, Brainiac 5 becomes a pure organic being as he discards his robotic armor. To cope with this new state and his recent actions, Brainiac 5 leaves the Legion. The robotic parts, in turn, combine to form a new evil Brainiac, leaving the series with a cliffhanger, which was intended to finish until the show was canceled. Brainiac 5 appears in the Smallville live-action series. In the season eight episode "Legion," Clark Kent and three Legionnaires (Lightning Lad, Saturn Girl, and Cosmic Boy) extract Brainiac from Chloe Sullivan's body, leaving his nanobots a condensed ball of metal, attempting to repurpose any programming they can use from the core to be friendlier. Brainiac 5 appears in the season ten episode "Homecoming," visiting Clark to show the past, present and future and help Clark come to terms with the darkness in his own heart in preparation for an upcoming confrontation with Darkseid. Actor James Marsters, who portrayed Brainiac in Smallville, returned to play Brainiac 5. Brainiac 5's character has been described by producers as "a slippery fish with a questionable moral compass" despite the reprogramming. Brainiac 5 appears in the TV shows set in the Arrowverse portrayed by Jesse Rath. Brainiac 5 appears in the third season of Supergirl. He appears as a member of the Legion of Superheroes. Brainiac is first mentioned only as Querl in the seventh episode, "Wake Up," by Mon-El. However, in his subsequent appearances, he is referred to as "Brainy" by his fellow Legionnaires, Mon-El and Imra Ardeen. In the season finale, his home time period has become uninhabitable and he stays in the 21st century. Rath was promoted to series regular for season four. In season 4, Brainy assists Supergirl, Martian Manhunter, and the D.E.O. in their fight against the Children of Liberty led by Agent Liberty as well as Lex Luthor's plot to discredit Supergirl. In addition, he also acts as a mentor to Nia Nal, an ancestor of Dream Girl's, when teaching her how to master her abilities; a romantic relationship between them eventually develops. J'onn, Brainy, and Nia later try to infiltrate a government base to save the apprehended aliens there. While J'onn and Nia are captured, the agents electrocute Brainy, inadvertently rebooting him and causing him to be exactly like his ancestors. He escapes and betrays J'onn and Nia, getting them deported with all the other aliens there. After seeing Nia Nal in mortal danger, Brainy's emotions returned and he went back to normal. During the fifth season, he continues to explore his relationship with Dreamer, but following the Crisis, an encounter with some of his surviving doppelgangers from other Earths prompts Brainy to disable some of his personality inhibitors to maximise his intellectual capabilities to oppose the plans of the organisation Leviathan, which leads him to ally himself with Lex Luthor to properly oppose Leviathan, operating on a principle of pure logic that causes him to ignore the issues of working with a known villain. Brainiac 5 appears in the Arrowverse crossover Elseworlds. He appears to assist Superman fight John Deegan in the form of a black suit-wearing Superman. When Deegan summons an A.M.A.Z.O., Brainiac 5 fights the A.M.A.Z.O. and defeats it. Rath's older sister Meaghan guest starred as a female Brainiac 5 in Season 5 of Supergirl. She made her first appearance in the January 19, 2020 episode, "The Bottle Episode," in which she was described as a version of Brainiac 5 from an alternate Earth. The episode also featured several other versions of Brainiac 5 resembling Rath's character, also from alternate Earths  .
