His reputation within the DC Universe's superhero community is often controversial due to his parentage, his callous methods, and his expertise in black magic.

Serving as the mystical member of the Outsiders team, he also guest starred alongside his teammates in Action Comics and Deathstroke the Terminator series.

After the series' end in 1995, Sebastian made occasional appearances in other comics such as Superboy and the Ravers but later had a larger role in the 1999 Day of Judgement crossover; he would initially appear with a revised history and detailing involving the Enchantress in the DCU Villains Secret File and Origins comic released ahead of the event depicting him as a villain.

In the actual crossover event, however, much of the details was changed though he still held a significance with Enchantress and was among the characters within the Sentinels of Magic team.

Faust would later star in the 2001 JLA: Black Baptism storyline as one of the main characters, his origin from the Outsiders run revised as well as the nature of his powers.

A rebooted version of Sebastian Faust debuted in the backdrop story of Suicide Squad: Black Files with a new origin, connections to the fictional agency, A.R.G.U.S, and characterization as an eco-terrorist and anti-villain.

Faust cannot properly process emotions although he does not completely lack them, able to feel romantic love and familial friendships with those such as June Moone/Halo (former) and Blue Devil (the latter).

He is unable to initiate any sort of intimate contact with individuals nor look directly at others without his aviators in fear of sucking their soul or draining them of their magic.

[1] While considered a world-renowned soul mage, members of the Justice League (notably Superman and Batman) expressed hesitance & distrust in working with Faust.

[5] In DC Rebirth, his reputation is portrayed to being far more positive, considered a top notched governmental agent and a known hero among the superhero and mystic community.

His turn from hero to villainy and eco-terrorism symbolizes the desperation he faced wanting to save both his unborn child and wife.

Despite this direction in his life, the Justice League are portrayed to being sympathetic to Faust's circumstances and both expressed interest in helping him rehabilitate for his crimes and were unwilling to allow punishment at the hands of Suicide Squad handler, Amanda Waller, who was speculated to have planned to bring Faust into her magical division of the Suicide Squad.

The actual crossover dealt with the two first meeting one another with Faust having come to be attracted to the June, only to have nearly slain her Enchantress personality to re-ignite the flames of Hell with a truly evil act.

The ordeal riddled Faust with guilt, having begun developing feelings for her despite June's relationship with Alan Dell but ultimately decided to keep his distance.

[10] Their relationship is depicted differently in the later Black Baptism event, with June being an exception to Faust's usual inability to forming romantic attachments due to his lack of soul (revealed in the storyline).

Still ridden with guilt over the events of Day of Judgement, Faust visits June frequently, as she was admitted to a hospital on due to the supposed death of her Enchantress personality slowly killing her and leaving her in a nearly unresponsive state, and repeatedly apologizes with lingering hope the two would reunite and continue a relationship should he find a way to reverse her circumstances.

Eventually, Faust helps join June back with her Enchantress persona, birthing a new one known as "Soulsinger" who seemingly is moved by his later "sacrifice" during a battle with a powerful sorcerer.

[2] In his new continuity incarnation in DC Rebirth, Faust mentions having met and fell in love with a dryad woman during his days as a director of A.R.G.U.S, the two having married and bore a son.

[2] Growing up, Felix's manipulative nature extended not only to Sebastian but his mother, who developed acute myeloid leukemia after birthing Fauna.

Over the course of the story, he works both with and against the Justice League, before ultimately tapping their souls to stop the mighty sorcerer Hermes Trismegistus.

Faust was first mentioned in the 2006 Checkmate series as a consultant brought in by the intelligence organization to program magical capacities and defenses into their technological creation, Gideon-II.

Using his expertise in the occult, he helps the Justice League and the JSA defeat the consciousness of the Starheart, who has taken the form of famed hero and Green Lantern Alan Scott and taken control of the newest incarnation of Doctor Fate, Kent V. Nelson.

Unlike the previous continuity, he is American and no longer wears sunglasses, having pupils in his eyes despite possessing no soul.

[3] Faust would make a brief appearance in the Other History of the DC Universe within Katana's recount taking place during the Outsiders series.

Initially considered skilled but inferior to his father, Felix Faust, he later emerged as a significant supernatural force, ranking among the most formidable magic users on Earth.

[2][13] In DC Rebirth, Faust practices "logomancy," a form of magic similar to hero sorceress Zatanna.

[15] In addition to his magical skills, Faust is a proficient occult investigator and possesses extensive knowledge of the supernatural.

His pouches, made of high-grade steel and concealed within a medium-sized cloth bag, have mystical properties that allow them to hold a vast number of artifacts, energies, and surprises.

The more time people spend in his presence, the more prone they become to feeling tense and irritated, making it challenging for Faust to form meaningful relationships and difficult for him to process emotions.
