Halo is a being comprised of two separate entities. One of them is an Aurakle, a member of a group of being that emerged from the Source billions of years previously. They were generally observers only in sentient affairs, and rarely interfered directly. Eventually this specific Aurakle came to be interested in organic beings and focused its attention on Earth and a young girl named Violet Harper. Violet formed the other half of Halo. She was running away from her past as she hid in Markovia from the crime lord Tobias Whale. He had hired an assassin, Syonide, from the criminal organization the 100 in order to kill her. After Syonide was successful at killing her, the Aurakle animated her body with its own power, reviving her to life, but with amnesia. She was subsequently found and recruited by Batman to serve as a member of the Outsiders.
Halo's first appearance was in the Brave and the Bold #200 in 1983 as part of a bonus insert intended to promote the new team. At the time DC Comics had two major team books set in contemporary times, the Justice League of America and the Teen Titans. Desiring a younger and edgier team to compliment their other titles, DC decided to take advantage of the popularity of Batman. Conveniently Batman had an already ongoing dispute with members of the Justice League over their operations. Thus he broke from the team and formed his own group with himself as its leader. The group was comprised of mostly new or relatively obscure characters - Geo-Force, Black Lightning, Katana, Metamorpho and Halo - and gained its own ongoing monthly series. The series itself was relatively popular and assured Halo an ongoing place at DC Comics
As a character introduced to readers as already having amnesia, Halo has undergone a fair amount of character development, first and foremost in discovering and reconnecting with her past. As a result of the process of her revival and the resulting amnesia she was often portrayed as quieter and withdrawn but as she has reconnected with her past and her humanity she has become more vocal, though still reserved to a degree. Furthermore she has become close friends with certain members of the team, primarily Katana, Windfall and Looker. Despite being composed of two separate entities it is only her human side which has cognitive control of her body, thus the Aurakle is seen (through the manifestation of her powers) but never heard. Because of her reborn nature she is often portrayed as somewhat of an innocent.
Major Story Arcs
As a character who was introduced with amnesia, many of the early stories focused on Halo dealt with her discovering her true identity or adapting to her new life. Upon return from Markovia and after joining the team she is given a new identity by Bruce Wayne (Gabrielle Doe though often referred to simply as Gaby). Her team-mate Katana became her ward during this time, the beginning of a long and strong friendship between the two. In order to better understand her past, Batman hired a private investigator (Jason Bard) to investigate her past. He eventually discovers her family and previous life in Arlington, Missouri. It is revealed that her real name is Violet Harper. This is noted as she never uses the violet portion of her aura. She thus returns to live with her human parents (Sam and Margaret Harper) and deals with her haunted past and the love of a newfound family.
When Tobias Whale discovers that Violet is again alive he and his associates seek to regain something which she had previously stolen, although they were unaware that she was a member of the Outsiders. This leads to torture like experiments on her to retrieve the formula for a drug from her photographic memory at the hands of Doctor Moon. Her teammates intervene and save her but sadly her parents die protecting her. Halo buries them and accepts that they died believing their daughter had returned to atone for her sins. soon after she starts experiencing severe and mind-altering dreams. Desperate to discover a link to her past, the team commandeers discarded Justice League equipment (on the satellite). Doctor Jace induces her memories as an Aurakle, which summons other Aurakles who have come to Earth to reclaim her into their numbers. She is subsequently freed and the influence of the Aurakles is removed from her.
Halo then returns to Gotham where she meets a man named David who invites her into a commune called Eden. Unknown to her this group is a front for Kobra and his terrorist organization. She is soon rescued from their influence by the team and she is thankful to David for helping her to get better in touch with humanity. She soon is introduced to another aspect of her humanity as she grows concerned over her own mortality after being stranded on an island by the Bad Samaritan. At this time she also develops a strong friendship with Windfall, a former member of the Masters of Disaster, as the two bond over similar ages and experiences. She also experiences her first birthday at this point with a new costume from her guardian (and also receives braces to fix her teeth.)
After some time her aura is seen to shift to violet, indicating her original personality has resurfaced. With a more criminally oriented outlook she turns on the team and allies herself with a woman named Marissa Baron. The two of them are later killed in Gotham at the hands of the cyborg Sanction. Her essence is transferred to Marissa, thus reanimating it with all her former memories and powers. The remainder of Violet is turned into the villain Spectra by Kobra. It takes her some time to grow accustomed to her new form. In her confused and weakened state, the Aurakles attack once again although they are eventually fought off. Following this she develops an attraction to Sebastian Faust and follows a splinter faction of the team that included herself, Faust, Looker and the Eradicator. However, this is a short lived development as the team soon bands together again and returns to Markovia during the Day of Judgment crossover as she helps seal a gateway to hell.
This events served to partially sever her ties to the team and thus Halo is presented mostly as a background character in the following DC wide crossovers - Infinite Crisis and 52. During Infinite Crisis she joins a makeshift group of superheroes defending against a breakout of supervillains from Alcatraz Island. She subsequently joins other heroes in the Battle of Metropolis (during which she saw two of her former teammates, Looker and the Eradicator, apparently die). She has a smaller role in 52 where she is seen aboard a spacecraft scanning the cosmos for a group of lost heroes. She eventually discovers the faint traces of a Zeta Beam and once it is honed in on numerous heroes have returned to Earth due to her help - Cyborg and Firestorm (who have been fused together), an enlarged Hawkgirl and Alan Scott.
Following the death of Batman at the hands of Darkseid, she is invited to Gotham by Bruce Wayne's loyal butler Alfred. In the event of his death Batman had created a number of contingency plans which involved among other things, the reconstitution of the Outsiders. Halo is invited to become a member of this team which intends to respect Bruce's final wishes. The new team is forced to sever all contact with their relations, and with time to visit them before this occurs, Halo unexpectedly shows up in the batcave early, referring both that she has no family and that if she did in fact have one that is was with her teammates. She also reaffirms at this time that she is aware she is Violet.
The Outsiders (consisting of Halo, Black Lightning, Metamorpho, Katana, Owlman, Geo-Force and The Creeper) return to the Batcave at the request of Alfred. Alfred (via hologram) informs them that after Black Mask destroyed Arkham, he implanted micro-bombs in Mr. Freeze, Killer Croc and Clayface, and he would destroy them if they didnt do what he asked. Instictively, all three inmates ran away, as far from Black Masks control as possible. Black Lightning and Owlman are tasked with tracking down Freeze. They track down freeze near a now frozen hospital near the arctic. Freeze stole surgical equipment to remove the chip, but needed sub-zero temparetures to perform the surgery. As Black Lightning and Owlman burst in, Freeze realizes he needs a large power source to power the equipment. He captures Black Lightning and begins to drain his power, only to be knocked out by owlman. His chip is later removed.
Geo-Force and Metamorpho then travel to Arizona to get Clayface. They discover Clayface has kidnapped a miner and his children to go inside him and remove the chip. Geo-Force realizes Clayface can change his material, so he cant control him. They eventually trick him into a cave, blowing him up with methane. They leave him at the base with Mr. Freeze so he can reconstruct.
Finally, Katana, Halo and The Creeper are tasked to catching Killer Croc in the Louisiana Bayou. Croc has been chewing off his own limbs in hopes to remove the chip, quickly regenerating because of his reptile metabolism. After dispatching Killer Croc and having a small run-in with Man-Bat, Halo and Katana drive Croc back to the base, with Creeper "keeping him company". Their truck is suddenly destroyed, sending Croc and Creeper skidding into the forest. Katana realizes their truck was destroyed by Maseo, Reiko and Yuki, her family resurrected as Black Lanterns. Yuki and Reiko go after Creeper and Croc as Katana fights against her husband. Angered, Halo eventually finds the right frequency of light to destroy the Black Lanterns.
While this is happening, Geo-Force, Metamorpho, Owlman and Black Lightning are recuperating at the base while keeping an eye on a frozen Mr. Freeze and liquified Clayface. The wall is suddenly destroyed by Terra, the deceptive sister of Geo-Force turned Black Lantern. She attempts to plead with the team, explaining what she did to the Teen Titans before she arrived at the base, and saying the ring is forcing her to be evil. She gets as much emotion as possible from her brother, pleading with him to kill her. This, of course is a ruse. She quickly traps the team while their guard is down, and prepares to feed on their hearts, saving Geo-Force for last. Katana, Halo and Creeper arive with a defeated Croc, to see Terra about to kill Owlman. Geo-Force and Black Lightning quickly free Owlman, Owlman quickly cuts off Terra's hand (with her ring still attached). Just as its about to reform, Halo uses a new light frequency, turning Terra to stone before her ring could return to her. She then realizes the dead are rising everywhere, and says she is needed. She then disappears to an unknown location.
Looker was apparently killed when the Outsiders were caught in a satellite explosion caused by Lord Death Man, though the team was later revealed to have survived due to Metamorpho's abilities. In the New 52 continuity caused by Flashpoint, Halo is now a member of the Dead Heroes Club, a group of supposedly-deceased heroes (consisting of herself, Freight Train, Looker, Batwing, El Gaucho and the Hood, and Wingman) who perform covert missions for Batman Incorporated.
Powers and abilities
After entering the vessel of a human being, Halo retained certain abilities from her former state as an Aurakle. She can generate glowing auras of energy about herself, each of which corresponds to a different color of the spectrum and give her a distinctive power when she switches from from one to another. The specific amount of power behind these abilities are not certain, it is assumed that in a human vessel that they are hindered but this has not been ascertained. It could very likely be that Halo can still achieve close to some of the level of power even not being in her original state. Any use of her light powers cause a "Halo effect" around her, her aura of light. All of these many colors of the spectrum allow her to fly, most recently at light speeds, which had not been obtained before. There is also can shine with a white aura which has shown no other ability save flight.
- Violet: all the power's at once; it gave the sociopath personality of Violet Harper control of the body, enabling her to use any or all of Halo's powers.
The negation of the color spectrum will also negate Halo's light based powers; the DC universe has many villains with just such abilities. Now that the Aurakle entity resides in a human host, Halo is quite aware of her mortality. Any amount of great physical harm will destroy the vessel and force out the Aurakle from its host. However In the 1990s it was shown that should the human body be destroyed, the Aurakle can merge with another freshly-dead human. It can be assumed that Halo may return in yet another human form at one time or another in the mainstream DC Universe.
- In the world of cartoons Halo appears in a few series such as Batman: the Brave and the Bold, and Justice League: Crisis on Two Earths. The first has Halo appear in the episode "Requiem for a Scarlet Speedster" as part of the Outsiders along the original members, Katana, Geo-Force, Black Lightning, and Metamorpho. Here she helps battle the forces of terrorist organization of KOBRA.
- The second Halo appears in the Justice League: Crisis on Two Earths movie as part of the Justice League in an alternate Earth as a parallel character going by Aurora. However in this representation Halo/Aurora is on the side of evil. She exhibits pink energy which works much like Green Lantern's ring minus the ring itself.
