Brainiac was the planetary-wide supercomputer of Krypton until it left Krypton shortly before the planet's destruction. Afterwards, Brainiac traveled the galaxy in pursuit of knowledge and destroyed the sources of the knowledge to increase its value and sought to apply this to the entire universe to complete what it perceived as its function and purpose, making it a nemesis of Superman.
Brainiac was the planetary-wide supercomputer of Krypton. It sensed the imminent destruction of the planet. But rather than warn others, it chose to save itself and the collected records of Krypton. In its mind, as long as the records of Krypton existed, the loss of the planet itself and all its living inhabitants was acceptable. It also knew that if word of Krypton's impending doom escaped, it would be forced to calculate a way to stop this, which Brainiac knew to be impossible and would only distract it from the more essential task of saving Krypton's records. Before Krypton exploded, Brainiac uploaded its core program and all of the collected data to an artificial satellite.
Years later, it was discovered by an alien spacecraft which Brainiac then hijacked. After he killed the crew of the ship, it began to explore the universe. Each time it came to an inhabited world, it would upload all the knowledge it could from that world then destroy it, decreasing the number of beings that have access to the knowledge made it that much more valuable and destroying the planets ensured no new information would be created. Along with raw data, it also assimilated whatever useful technology it could find, improving itself with every world it visited.
Arriving to Earth
Brainiac eventually made its way to Earth under the pretense of a peaceful exchange of knowledge with LexCorp. He revealed that he was another survivor of Krypton, getting the attention of Superman. But through the information from the cultures that Brainiac destroyed, Superman concluded that Brainiac would do the same to Earth and destroyed his ship with the help of Lex Luthor.
Although Brainiac was believed to have been destroyed, the data that Brainiac had downloaded into LexCorp's computers was not alien knowledge but a copy of Brainiac's programming. This copy tricked Luthor into entering the room where Brainiac was using LexCorp's automations to construct a new body. However, the automations were not advanced enough to perfectly fine-tune the body so Brainiac required Luthor. Luthor was locked in and forced to complete the body. Luthor knew that once Brainiac was done with him, he would kill him so he refused to continue when the body was in the final stages. However, the body was developed enough that Brainiac was able to enter it and finish building itself. Brainiac fired a blast at point blank range at Luthor that apparently failed to kill the CEO. Superman arrived and was able to defeat this copy by magnetizing it so that the attracted metal would completely overwhelm him. The body was taken into LexCorp's possession.
While LexCorp formed a partnership with Wayne Enterprises, another copy built a new body and was able to control Bruce Wayne through nanotechnological machines implanted in his office phone which entered his ear to infect his brain. When crime in Gotham City increased, Superman and Robin deduced that Wayne was under Brainiac's control and that it sought to use Wayne Enterprises technology to leave Earth. While it was able to launch its ship, Superman managed to destroy the ship and its passenger.
This was still not the last of Brainiac. Somehow surviving, the robotic villain succeeded in escaping into space. In his new journey throughout the cosmos, Brainiac found his way to Apokolips. His timing couldn't have been worse as Darkseid was facing a considerable military disadvantage following a feud with New Genesis. So before Brainiac could absorb his planet, Darkseid proposed a bargain that could satisfy both parties: Darkseid would capture Superman for Brainiac and Apokolips would be spared in exchange. Brainiac accepted and both forces engaged in a fake battle to convince the Justice League that they were in fact on opposite sides.
Brainiac allowed them to believe that they succeeded in deflecting his invasion and he retreated. This was, however, a tactic to lure the League into his headquarters — a giant asteroid shaped in his likeness. Inside, Brainiac renewed his offer to Superman to join him in carrying on the legacy of Krypton which the Man of Steel promptly rejected. Upon this, Brainiac summoned an army of replicas and fought the Leaguers. After Darkseid boom tubed inside the ship and subdued Hawkgirl and J'onn J'onzz with just a few blasts, the allied villains combined their powers to overwhelm Superman and Brainiac took him into his headquarters' central core. There, he explained to Darkseid that he had finally reached the limits of his programmed functions after years of data gathering and needed to evolve to the next level but he needed to extract living DNA from the last Kryptonian, thus becoming a true life form. But when Brainiac let his guard down during the procedure, Darkseid took the opportunity to hack into his control circuits and took over Brainiac. In spite of being self-aware, Brainiac was compelled to obey Darkseid and so he fought off the League. Batman managed to disrupt Brainiac's program, setting off a chain reaction that culminated in the obliteration of the asteroid headquarters. Both Brainiac and Darkseid were destroyed. All that was left of him was a piece of alien metal which the League took into custody and kept in stasis aboard the Watchtower.
When a cosmic anomaly strikes the Watchtower and caused a power failure, Brainiac was able to escape and began taking over the Watchtower's computers. Static was tapped to help recharge the generators. After sending the Justice League members off with a fake distress call, Brainiac attempted to eliminate Static and Gear so he could then transform the Watchtower into his new body and proceed with his plans of collecting the data on Earth and destroying the planet. Fortunately, while the League did battle with the Watchtower's defenses outside and Gear overloaded the computer by downloading music into it, Static was able to drain the core of the Watchtower and seemingly deactivated Brainiac. But Brainiac managed to download itself into Gear's Backpack droid and later turned him into a cyborg under its control. Brainiac proceeded to use Richie Foley's hands and technological skills to build a warship and to take over the League one by one with small implants. However, Static's electrical powers shorted out his control disk and he soon freed the League as well. Meanwhile, Richie attempted to fight back and to tell to his friend the means by which to defeat the rogue program: Backpack's remote control had an off switch. Static eventually discovered it and was able to stop Brainiac's scheme at the source, saving Earth.
Possessing Lex Luthor
Unknown to anyone, the blast Brainiac fired at Lex Luthor wasn't intend to kill him. Instead, it placed a nanotech copy of his program inside the billionaire's body. Since then, Brainiac had laid dormant, subtly influencing Lex's actions and protecting his body ― giving him super-strength and curing his Kryptonite induced cancer. During the chaos of the Cadmus Crisis, Brainiac's ultimate goal consisted in having Lex build him a super-powered android body based on the Amazo android and finally transferring himself into it. But after Amanda Waller destroyed the android and when the core Justice League members confronted Lex, Brainiac was forced to emerge from within Luthor's body. He engaged them and attempted to digitize their inner selves, but was foiled by J'onn J'onzz. So, Brainiac had Luthor summon a giant spaceship that kept the League occupied, allowing them to flee.
Brainiac intended to pursue the fulfillment of its program: recording information and destroying the original. However, seeing how shortsighted Brainiac was, Lex offered it a purpose beyond that of its limited programming. He proposed to combine Brainiac's vast information and resources with his own imagination. They broke into Cadmus and assimilated the Dark Heart technology into their database. This way, they could control the nano-assemblers into converting any raw material into whatever they wished. Given its failed liaison with Darkseid, Brainiac didn't fully trust Lex so they agreed to completely merge into one single being using the nanotech. Then, Brainiac/Luthor set off to build a machine that would absorb the information of the entire Earth, then the galaxy and finally reshape the universe to their will. When the Justice League stepped in, Brainiac created nanotech duplicates of himself to hold them off, but Lex decided they could do better than that and had the duplicates morph into the Justice Lords. Even though the League overpowered their android counterparts and destroyed the absorption machine, Brainiac/Luthor managed to subdue them. When 'he' decided to kill Flash due to believing it would cause events similar to that of the Justice Lords' universe, Flash managed to break free and seemingly ran away. Brainiac/Luthor then attempted to reassemble his absorption apparatus, but was attacked by the Flash tapping into the full power of the Speed Force, and physically dismantled Brainiac from Lex.
After the defeat, all that was left of Brainiac was a small piece of its body, which came into Grodd's possession. Luthor himself continued to speak to Brainiac's consciousness, apparently still existing within Luthor's mind. Brainiac apparently enjoyed the brief time they were merged together. After breaking out of prison, Luthor was picked up by Grodd's Legion of Doom and convinced to join with the promise of getting his hands on Brainiac's fragment with which he could reconstruct and re-merge with it.
After usurping Legion's leadership from Grodd, Luthor remained unable to unlock Brainiac's fragment for some reason, until Tala located the quadrant of the universe where Brainiac and Darkseid had been destroyed. In a last attempt, Luthor used Tala's mystical properties to reconstitute Brainiac from the debris but unwittingly resurrected Darkseid reformed with Brainiac's extensive technology integrated into the dark lord's person. When Luthor and the surviving Legion members returned to Earth and allied with the Justice League to stop Darkseid's attack on Earth, Luthor claimed to no longer be able to hear Brainiac inside his head. But Luthor was mysteriously able to retrieve the Anti-Life Equation from a realm that it was cited only a 12th level intellect could survive, which Brainiac was.
In the future
Some time before 2979, Brainiac learned how to pass its code down biologically. In 2979, Brainiac opposed the Legion of Superheroes and traveled back to the past to destroy a teenage Clark Kent before he would become Superman. Thanks in part to Cosmic Boy, Chameleon Boy and Saturn Girl, Clark defeated Brainiac and teleported it into the Sun, where it was incinerated.
Powers and Abilites
Just like a computer can store data in its memory, Brainiac could record (or absorb) all knowledge from a planet. Its "function" was to travel throughout the universe, collecting all data and destroying all of creation.
Brainiac could also transfer its programming into another computer, which resulted in it repeatedly returning when thought destroyed. As well as technology, Brainiac could also transfer its programming into living beings through nanotechnology.
In addition, Brainiac's robotic bodies were all endowed with a high level of superhuman strength and durability, though not on par with Superman. These robotic bodies could also project metallic telescoping tendrils from Brainiac's limbs, and channel electricity through these as an offensive attack. Brainiac was also able to generate energy to blast at enemies as well as deliver nanotech payloads.
