Brainiac

== Biography ==
=== Early History ===
Not much is known about Vril Dox’s origin. It is known that he had a pet monkey, Koko, who served as his lab pet for many years. He was an esteemed scientist from Yod-Colu who appeared at intergalactic conferences and was one of the first scientists of the modern galactic era (what Earthlings know as the 1700s-2000s) to make headway in artificial intelligence and travel into other zones of existence.
Vril Dox was part of a think tank for the intergalactic peacekeeping force known as L.E.G.I.O.N (Licensed Extra-Governmental Interstellar Operatives Network) which was set on creating the galaxy’s most advanced artificial intelligence. Dox was known as unruly in the group, often stealing prototypes to take back to Yod-Colu and improve the design, but he was never reprimanded because his tinkering worked.
However, one scientist named Telos working on the Think Tank took issue with Dox’s actions, and so he followed him back to Yod-Colu one night, where he discovered Dox had cloned himself and was using multiple versions of himself to work on the A.I. Telos reported Dox’s actions to the rest of the Think Tank, and he was tried, since cloning was deemed in the LEGION’s constitution to be unlawful and unethical.
Dox was exiled. As a last ditch operation, he sent his clones onto the LEGION facility to steal the intelligence they had created, COMPUTO, as Vril Dox believed it was his. Several of the clones were captured, some killed, and some escaped in pieces. While being pursued by a LEGION starfleet, Vril Dox returned to Yod-Colu and shrunk down his home city and took it in his ship and disappeared into interstellar space.
=== The Collector of Worlds ===
There is a scarce accounting of Vril Dox’s movements for decades. He holed up in a fleet of intergalactic ships, rebuilding his clones and exploring digital dimensions. He traveled the universe, where he became obsessed with cataloging life. He would travel to planets, shrink one of their cities, bottle it, and collect biological samples from it. His obsession grew so large, he eventually built the Terrarium, a satellite hosting a perverted Noah’s Ark of shrunken cities and biological samples of species from the planets he razed.
Legends started to call him Brainiac, and he adopted this name as his own moniker, dubbing the clones he created with different numerical signs (Brainiac 2, 3, etc.). One such clone, Brainiac 3, had his body destroyed in the fight with LEGION, but after a lengthy operation, Brainiac 1 saved his consciousness and uploaded it to the digital landscape to explore advanced societies. Brainiac 
This is how Vril Dox found Krypton. Brainiac 3 reported back that he had taken possession of an A.I created by Jor-El, and was using Krypton’s resources to build up an army of androids for Brainiac, while slowly depleting the planet and accelerating its demise. Brainiac 1 focused his attention here and learned as much as he could from Krypton’s advanced tech, even stealing a fleet of starfighters, before razing the planet and collecting Kandor on October 7th, 1973.
However, Krypton’s destruction proved to be bad news for Brainiac - the Reach, the Green Lantern Corps, and LEGION, now being led by one of his clones (refurbished and liberated) in the form of Brainiac 2, were all pursuing him. Brainiac decided it was time to go into hiding. He traveled to one of the far reaches of the Ghost Zone and stashed the Terrarium and sent many of his starfighters and clones on suicide missions to Oa, New Cronus, Rann, Cairn, and other high-profile intergalactic centers.
=== A New Beginning ===
Brainiac was left with fewer resources and piloting a lone ship. Lacking most of his clones and androids, he decided to lie and wait. His only escapes from solitude were his pet monkey Koko and Zor-El, whom he had saved from Krypton and tortured. He spent his days in the operating theatre with Zor-El, seeing just how far he could twist his humanity..
He reassembled resources and hid out on dead worlds, constantly evading the GLC and other intergalactic law groups.  At some point in his hiding, Uxas of Apokolips learned of him, and sent one of his scouts, Devilance the Pursuer, after him. Brainiac returned Devilance’s body to Apokolips - minus his head - as Brainiac found his skull to be particularly impenetrable and used it as the base for Terrarium II.
By the early 2000s, Brainiac had amassed back most of his resources. He set his sights on his next major conquest. He eavesdropped in bars and hidey-holes and was fascinated by the talk of Earth and its metahumans, alien presence, and significance in intergalactic relations. He set his sights on the planet - unaware it would bring him face-to-face with Krypton’s last survivors. He found himself a liaison on Earth - Gorilla Grodd, who began assembling the Legion of Doom and neglected to mention the Kryptonian heroes to his benefactor.
While on his way to Earth, he encountered a being known as the Futuresmith, a being Vril Dox recognized as his twelfth clone. The Futuresmith left a mysterious package in the cargohold of Terrarium 2 and spoke mostly gibberish before disappearing and leaving Vril en route to Earth.
Brainiac’s invasion of Earth did not end well. The combined might of the Justice League and the Titans proved enough to push him away, with the heroes’ cybernetically enhanced members, such as Cyborg, proving to pack quite the punch and be more formidable than he was expecting. Forced to sacrifice himself, Vril Dox shed his body and transported his consciousness to a backup starship and whisked himself into the cosmos.
Forced to sacrifice Terrarium 2, and having lost several assets including Brainiacs 1 and 8, as well as the Futuresmith’s mysterious package, Vril Dox went into hiding to lick his wounds again. From the scraps he had left he built himself a new body that was slowly refined by new genetic material.
Since then - the last Earth has heard from Brainiac was when he sent Zor-El to kill Supergirl. Zor-El returned to space on the hunt for the Collector of Worlds, but he has been bizarrely private. Recently, Telos has disappeared from LEGION - and Brainiac is the primary suspect. Some of his clones and genetic offspring have popped up, including Milton Fine, an Earthling who retained some of Brainiac’s consciousness from his time on Earth, and Techne, a new member of LEGION who was believed to have been sent as a sleeper agent - and is now on ice.
