Querl Dox


 * For the Coluan named Brainiac 8, see Indigo.

Querl Dox, also known as Brainiac 5, is a Coluan and a member of The Legion. A 12th-level intellect, Brainiac 5 is an incredible scientist and combat strategist, affectionately nicknamed "Brainy" by the other legionnaires. He also goes by the name Barney when operating among humans.

Early life
Querl was born in the 31st century on the planet Colu into the so-called "Brainiac clan". He is implied to have had a strained relationship with his mother. A genius with a 12th-level intellect, the highest ever recorded on the planet, Querl was inspired by the superheroism of the 21st century and Supergirl's ideals, as well as the story and legend about her. At some point in his life, he joined the Legion, a group of superheroes founded and led by the time-displaced Daxamite Mon-El.

While on a mission, Querl, Mon-El, Imra Ardeen and three other unidentified legionnaires hit a wormhole, and were transported 12,000 years into the past. They decided to put themselves into cryo-sleep until the 31st century, but Mon-El and Imra were awakened early when a torpedo hit their ship in 2017 and they later decided to awaken Brainiac 5 to help Kara after she lost her first fight against Reign.

21st Century
After Mon-El woke Querl to help Supergirl, they placed her in a suspension tank in the Legion's ship while they fitted her with a neural implant that allowed Querl to go into her mind. Once there, he found Kara in a mental simulation of her loft. He was surprised to find that everything seemed to be normal to both her confusion and irritation. He then introduced himself and told her that she was in a coma following her battle with Reign. However, it seemed like she was stuck. Back outside with the others, Querl told them that Kara seemed healthy enough but couldn't seem to wake up.

Personality
Querl is an extremely intelligent, logical, but compassionate individual. In the beginning, Querl's compassionate nature was shown in his efforts to help Kara awaken from her coma. Mostly likely due to being a synthetic being, Brainy sometimes comes off as socially awkward and slow to pick up on people's feelings.

However, Querl's massive intellect boasts an equally massive ego, calling himself a "12th Level Intellect", coming up with impossible solutions with technology that doesn't exist yet or dismisses other people's ideas in favour of his own. In addition, he makes his decisions based on logic and calculations, which is why he sided with Imra in her quest to rid themselves on Pestilence in order to save the millions of lives in the future. He is also shown to overestimate his capabilities, especially back in the 21st century where the technology is far more limited than to what he is used to.

Powers

 * Coluan physiology: Being a synthetic life form, Querl's physiology allows him to shape his body and interact with technology.
 * Cybernetic interface: Querl is a Coluan cybernetic being. He is able to transfer body in the form of digital code and teleport through any technology by flying into it while in digital form. He can use any electronics as a portal to another destination, traveling through electronic and digital signals, while he is unable to travel through older broadcasting signals. He can interface with any machinery and manipulate computer systems, as well as detect digital electronics and signals, while he could not do so with older broadcasting signals and technology. Being incredibly multitasking, he can project his own mind into another via cybernetics devices and maintain enough clarity to speak at the same time with the person to which he is connected and the others in the real world.
 * Super strength: Querl's strength allowed him to fight a Kryptonian on equal grounds.
 * Super speed: Being a Coluan, Querl is also showcased blinding levels of speed.
 * Flight: Being a Coluan, Querl has the ability to fly, all tho since he mainly uses his legion ring to fly it is unknown to how well he is capable of flying.
 * Invulnerability: Querl's body is denser than a human's but not nearly as durable as a Kryptonian's.
 * Self-repair: As a digital being, Querl is able to self-repair, though only if he is conscious, otherwise the Omegahedron can be used to reconstitute him.
 * Shapeshifting: Being a Coluan, Querl can change his appearance.
 * Malleability: Being a Coluan, Querl is able to manipulate his limbs to stretch and elongate to almost no limit and turn his limbs into blades that can pierce into Martians. He is able to absorb bullets harmlessly into his body if shot.
 * Abilities via Legion Ring: Each member of the Legion is granted a special ring that serves as a form of identification, along with granting each member several other capabilities.
 * Flight: The ring has been shown to enable Querl the ability to fly through unspecific means. It seems to be activated through a telepathic suggestion, as no thoughts or movements were taken to activate it. It appears that it allows Querl to fly in a more hover-like stance rather than the typical vertical form of flying found in Martian Manhunter or Supergirl.
 * Telepathy immunity: The ring has been shown to give the wearer the ability to resist telepathic abilities such as when M'yrnn J'onzz loses control in the DEO and cause everyone to display violence towards each other.
 * Oxygen independence: Querl‘s ring grants him the power to breathe unaided in harsh environments such as the vacuum of space.

Abilities

 * Genius-level intellect: Querl has a "12th-level intellect", which grants him superhuman calculation skills, amazing memory and exceptional technical know-how. This increased intellect gives him superior calculating abilities, an encyclopedic memory and innovating scientific knowledge even by Coluans standards. By concentrating the power and disciplined nature of his mighty mind he safely operated many 31st century devices with ease.
 * Skilled hand-to-hand combatant: As a Legionnaire, Querl has participated in Legion combat training and is an adequate hand-to-hand combatant. However, he has yet to overly exert himself in this regard, given his sophistication, such that his personal fighting style leans more on the defensive, and is content with simply and calmly dodging incoming strikes.
 * Psychotherapy: Querl is trained in psychology and tried to use his skills to enter Kara's mind and help her to wake from her coma.
 * Expert pilot: Querl is an extremely skilled pilot, being able to driving The Legion cruiser when in battle with Reign.
 * Hyper-metabolism: As Querl even states himself, he has the capability of recovering from alcohol libation with remarkable speed.

Weaknesses

 * Computer viruses: Since Querl is an A.I., he can be subjected to computer viruses.
 * Emotional disruption: Querl can be rendered unable to use his advanced intellect when disrupted by current emotional stress; for example, the experience of being prejudiced by his former friend at a pizza shop prevented Querl from completely focusing on a mission to help Kara escape from the Children of Liberty at L-Corp.

Equipment

 * Legion suit: Querl wears a protective suit during battle.
 * Legion flight ring: Querl's legion ring allows him to fly.
 * Image inducer: Querl uses a inducer to make himself look like a normal human; when he goes out in public.

Trivia

 * Indigo is also Coluan, and another descendant from the "Brainiac clan", originally called Brainiac 8. However, as of now, there is no confirmation of what the lineage connection between Brainiac 5 and Indigo is.
 * He uses the alias of "Barney" when purchasing coffee and pizza.
 * Querl's favorite pizza is apples and olives.
 * Unlike Alex and other members of the DEO who needed J'onn to alter their memories to forget Kara is Supergirl, Brainy retains his memory as 21st century methods of interrogation are useless on him.

Behind the scenes

 * In the DC comics, Brainiac 5 is a descendant of the well-known enemy of Superman, Brainiac, a prominent member of the Legion of Super-Heroes, and one of the longest romantic partners of Supergirl.
