Aquaman became a version of this in The '90s in Aquaman (1994) and lasting until Infinite Crisis. He grew his beard out to adopt a Father Neptune look, and lost one of his hands and had it replaced first by a hook and then by a form-changing magical water-hand. He also adopted a more aggressive attitude on behalf of Atlantis. These changes were actually very well-received by much of the DCU's fanbase, and is considered an implementation of this trope that actually worked, as the goal of Peter David's revamp was to essentially rescue Aquaman from the scrappy heap that Superfriends had left him in. Unfortunately, until the release of the movie, much of the general public was still unaware of the revamp, and still pictured poor Arthur as he was in Superfriends. One thing that saved Aquaman from the negative qualities of the 90s anti-hero is that the book was often funny, and while he might have had more of an edge, he didn't take himself too seriously either. Because, you know, Peter David.
Koryak, Aquaman's Inuk son introduced in the Peter David run, was a straighter example of this. He was arrogant, hot-tempered, prone to violence and was a rival/foil to Garth, the original Aqualad. Koryak did mellow out later on after he unwittingly caused a war between Atlantis and the sea god Triton and was banished from Atlantis by his father. Koryak could be considered a deconstruction of the 90s anti-hero given that his aggressive and antisocial tendencies are frequently criticized and often lead to disaster and it is not until he becomes a nicer person that he is accepted by his father.
The Authority: The Authority represent an entire Justice League of Nineties Anti-Heroes. They are, however, unusually idealistic for their kind, as part of their remit is to "make the world a better place". Their methods, however, seem to involve copious amounts of ultra-graphic violence (no Thou Shalt Not Kill for them), ruthless cynicism towards their enemies, and disdain for opposing points of view — they once overthrew the government of the United States.
After having his back broken in Knightfall, Batman is replaced by Jean-Paul Valley a.k.a. Azrael, a character with no compunctions about killing. Azrael is chosen by Bruce, who is then chewed out by Nightwing over it, and Bruce himself admits it was one of his worst mistakes. Azrael, especially his time as Batman, was written as a Take That! towards those who wanted Batman to act more like The Punisher, though he was still written as a sympathetic deconstruction, in that he is shown to suffer from mental illness from his brutal upbringing by the Order of St. Dumas' Program rather than being a Tautological TemplarJerkass like many other examples of this archetype were. From the moment after he meets and befriends psychiatrist Brian Bryan, Valley becomes more of reconstruction of the trope.
Jason Todd (Batman's second Robin) has been a Nineties Anti-Hero type ever since he came Back from the Dead. Amusingly, he was absent for the entire decade.
Around 1994, Guy Gardner, a roughnecked, "macho" member of the Green Lantern Corps, was reinvented as "Warrior," with ridiculously huge muscles, tattoos all over his body, and the ability to form his arms into any kind of weapon he could think of, mainly gargantuan guns. Rumor has it that the reinvention was the result of writer Beau Smith writing the pitch as a joke and accidentally having it approved. He eventually reverted to his old (but still roughnecked) Green Lantern persona after the fad played itself out.
Word of God in the letter column was that after Guy lost his briefly-used Qwardian ring, Beau wanted to reinvent Guy as an Indiana Jones/Race Bannon type globe-trotting adventurer, no powers had or required. This did not get approved.
Jack T. Chance, who first appeared in 1992, was the Psycho Party Member for the Green Lantern Corps. He was the only Green Lantern allowed to kill, and confined to his homeworld, which was a Wretched Hive so horrible that every Lantern that was sent there was killed within a week.
Green Arrow: Purposely averted with the Chuck Dixon run, as Connor Hawke is a passive martial artist who has lived at a monastery for 2 years by the time that his father dies and he becomes Green Arrow. In fact, he is so resigned that he actually becomes the peace breaker in the Flash-Lantern-Arrow trio (He has to break up the senior Wally West from the junior Kyle Rayner). The trope is also played with with thr supporting character of Eddie Fyers, an espionage officer who has no qualms against killing or other dirty deeds, and is only held back from doing so by Connor as a promise to his father, Oliver Queen.
Kingdom Come: The series by Mark Waid and Alex Ross was in part a savage denouncement of Nineties Anti-Heroes, and was one of the things that caused the changeover from the Dark Age to the Modern Age. One of the themes of the comic was the classic generation of superheroes fighting the violent "modern" heroes. Of course, the "classic" heroes shared some of the blame as well; many became just-as-violent Knight Templars attempting to deal with it. The "face" of the anti-heroes, Magog, is practically every Dark Age stereotype rolled into one cybernetic, sacrilegious package (though Waid and Ross admitted a certain fondness for him due to how over-the-top he was). In a brilliant twist of idealism, Magog realizes how screwed up he is, turns himself in, renounces violence, and is one of the people left alive at the end; in the prose novelization of the story, he becomes the Dean of Students at Paradise Island!
Magog himself was able to pull a Canon Immigrant, and was introduced in the Main DCU in a JSA storyline. In 2009 he got his own solo series, which is something of an Affectionate Parody of the old school Nineties Anti-Hero. His Rogues Gallery includes an insane homeless man with mind control powers and a silver haired woman who talks like a 1980s valley girl.
Lobo: Lobo was created to parody this sort of character, even though he came out of the early 80s. Later played straight at times after he got a lot of Misaimed Fandom popularity.
Milestone Comics: Every number one issue of a book was written like one... and then every issue from then on subverted it. Unfortunately, this had the effect of painting the comics as "me too" and never caught a foothold (save Static, who had his own animated series.)
During Grant Morrison's run on Action Comics, in one alternate universe Lois Lane, Clark Kent and Jimmy Olsen created a device that would allow the user to create a super-powered Tulpa. They wanted to create The Cape, however the executives thought this trope would have more wide-market appeal, and deliberately attempted to invoke it.
During The Death of Superman, Superman had an Anti-Hero Substitute in the form of the Eradicator, one of the four replacement Supermen who appear after he dies. He's portrayed as a negative version of the trope, finding himself being lauded by Guy Gardner, which makes him question things, and chewed out by Lois Lane and Steel for using the S-Shield and causing death and destruction in its name.
At the climax of the story Superman briefly becomes a '90s Anti-Hero following his resurrection. Since his powers are taking longer to regenerate than the rest of him, Superman storms the villain's lair with two large guns and bandoliers, an all black suit, and a mullet. Thankfully it doesn't last, except unfortunately the mullet.
In the Elseworld story Superman: At Earth's End, Superman is portrayed as this, being depowered and having to rely on huge guns, being a lot more willing to kill, and drawn to be overtly muscular and with huge pouches.
At the time, it was a dreadful setback for the idea of "grown-up" superhero comics. In hindsight, it was America's inevitable reaction to Watchmen, and the only response that could possibly be effective: Fuck realism, we just want our superheroes to look cool and kick ten thousand kinds of ass.
Wonder Woman: During late '94, the Wonder Woman office had decided they also wanted in on that action. Enter Artemis of Bana-Mighdall, the kindest and most open-minded member of a splinter tribe of Amazons... which meant she was still a Hot-BloodedJerkass several magnitudes more violent than Diana on her worst day. Artemis' tenure as Diana's Anti-Hero Substitute was a lot shorter, lasting only about six issues (and a handful of cameos in Justice League titles and the like) before she was killed off. A while later, she was resurrected, become a part-time demon slayer, and ultimately mellowed out into a regular member of Diana's supporting cast.
◊, however, he didn't act like a 90s Anti-Hero at all, and was lauded by fans in the letters column for having a certain "Indiana Jones" charm to him.
