This strike team of covert operatives consisted of August Durant, Lili de Neuve, Carlo di Rienzi, Mike Tempest, Crimson Dawn and King Savage.

Writer Martin Pasko and artist Dan Spiegle introduced an updated version of the team as an eight-page feature in the anthology title Action Comics Weekly #601 (May 24, 1988).

[5]A second arc of this team, by writer Pasko and original Silver Age artist Springer, ran in Action Comics Weekly #619–630 (September 27 – December 13, 1988).

Unlike previous versions of the team, the new Secret Six consists mainly of villainous characters who undertake missions of dubious moral quality and often resulting in a high body count.

In the 2006 Secret Six limited series, (written by Gail Simone with art by Brad Walker and Jimmy Palmiotti), Knockout, who was revealed as a mole infiltrating the Society in Villains United, has officially joined the group to be with her lover, Scandal.

DC launched a new Secret Six series in September 2008, reuniting Catman, Deadshot, Scandal, and Rag Doll, and adding Bane (hinted at by Simone months earlier as "an A-list Batman villain"[8]) and an original character named Jeannette, who appeared in the third issue.

The Six have been hired to retrieve Tarantula from Alcatraz Island, and find a card which she stole from "Junior", a mysterious villain who supposedly runs the entire West Coast mob.

[9] Soon, the Six are attacked by a small army of supervillains, all wanting to recover the card and collect the reward of $20 million for each of the Six, under the orders of Junior, who captures and tortures Bane, whose strong principles and moral convictions, paired with his fatherly fondness of Scandal, keep him from betraying his new team.

The crossover involved the Six being hired by an anonymous party (in reality Amanda Waller) to break into Belle Reve prison in order to rescue an inmate, only to discover that the mission was a trap set in place so that the Suicide Squad could apprehend the team and kidnap Deadshot.

The book's final storyline featured Bane leading the Secret Six on an ill-fated mission to Gotham City, where they plan to kill Catwoman, the Red Robin, Batgirl and Azrael.

The series features a completely new line-up, save Catman and Black Alice, including Strix, the Ventriloquist (Shauna Belzer), Ralph Dibny under the alias of Big Shot and a new character named Porcelain.

In the next issue, Scandal Savage, the Rag Doll and Jeannette appear acting as operatives of Mockingbird, tracking down the team, but later the three characters become allies to the Secret Six and turn on the Riddler.

After the portal is closed due to the combined efforts of Batman and Superman, the team (minus Gordon, who was apprehended shortly afterwards) does battle with Lex Luthor in the Year of the Villain: Hell Arisen miniseries.

The team is disbanded when the Batman Who Laughs is injected with a cure for his serum, causing the Six to return to normal and turn on him before they are interrupted by Lex teleporting him to the Godhead.

An alternate universe iteration of the Secret Six appears in Tangent Comics, consisting of the Atom, the Flash, the Joker, the Spectre, Plastic Man, and Manhunter.

An alternate universe iteration of the Secret Six appear in Tiny Titans, consisting of Bane, Rag Doll, Jeanette, Scandal Savage, Catman, and Deadshot.

The stories have been collected into trade paperbacks: In 2018, Suits's Rick Muirragui was attached to write and produce a Secret Six TV series with Bill Lawrence's Doozer Productions for CBS.
