Knockout is a supervillain in the DC Comics universe. She first appeared in Superboy (vol. 4) #1 (February 1994), and was created by Karl Kesel and Tom Grummett.^[1]

A former Female Fury warrior from the hellish planet Apokolips like Big Barda, Knockout also escaped to Earth. Though while Barda became a superheroine, Knockout became a supervillainess. She later joined the Secret Six team, which committed actions more as antiheroes.

Knockout was originally a member of the Female Furies before being inspired by Big Barda and Mister Miracle escaping Apokolips and deciding to leave as well.^[2][3] She fights Superboy before being recruited into the Suicide Squad to fight the Silicon Dragons cartel.^[4][5][6][7] However, Superboy manages to defeat her and bring her into custody.^[8]

In the storyline Hypertension, Superboy meets several alternate universe variants of Knockout while traveling through Hypertime. The main universe version later joins the Secret Society of Super Villains as a mole at the request of her lover, Scandal Savage.^[9]

Knockout later joins the Secret Six alongside Scandal before almost being killed by an assassin with a Thanagarian sniper rifle.^[10] During the Final Crisis event, she is killed by Infinity-Man before eventually being resurrected.^[11][12][13]

Following her resurrection and a period of mental recovery, she rejoins the Secret Six and accompanies the team on a mission to Gotham to kill several of Batman's allies.^[14] While in Gotham, Scandal proposes a polygamous marriage between Knockout, herself, and the stripper that she had been dating while Knockout was still dead. Knockout accepts the proposal just prior to the team being ambushed by a number of superheroes who come to assist Batman, resulting in a massive battle. Knockout is quickly blasted in the face by Captain Atom, and falls to the ground next to Scandal. The two women hold hands one last time, with Knockout referring to Scandal as her "wife" before losing consciousness. The fates of Knockout and the other members of the Secret Six (save for Bane) are ultimately left ambiguous as the series ends.^[15]

During the next Secret Six series set in the New 52, both Scandal and Knockout are shown to be perfectly healthy and living in freedom instead of prison, and are still happily together with Liana. The three make plans to have a child together, and Scandal has even chosen the man she wants to be the donor.^[16]

In Generations, Dominus pulls Knockout and a group of supervillains from various timelines to stop a group of heroes from thwarting his plot to change history. However, the villains later defect to the heroes to help them defeat Dominus.

In Catwoman (vol. 5), following DC's Infinite Frontier relaunch, Knockout appears as one of several supervillains gathered by Clayface to help Catwoman defend her neighborhood from Gotham City's new fascistic mayor and paramilitaristic enforcement militia.^[17]

Knockout is a highly trained warrior and master of unarmed combat. Like most other New Gods of the planet Apokolips, she has immense strength, stamina, and durability, as well as a healing factor.^[18]
