DC K.O. Reading Order: How To Read The Biggest Cosmic Tournament in Comics History

DC K.O. #1 variant cover by Dan Mora

Whether in comics, animation, or movies, we always love a good superhero fight. That clash of egos, which only their mind and fists (and sometimes a bit of plot armor) can solve. DC K.O., DC Comics‘s newest big event, promises to shake the world with a big tournament. Heroes and villains gather to conquer the Heart of Apokolips and stand above all, but who will win? And will they succumb to the Heart?

DC K.O. is a 42-issue event full of all types of fights, from 1v1s to all-out brawls. And now that the tournament is done, it’s time to go back and read everything, from front to back — whether you missed it, or just want to relive the madness, once again.

We’ve written a list with synopses for every chapter in the event, prologues, tie-ins, and the main story. You can also check a cleaner list with only the chapter names at the end of the article. Draw your weapons and have fun!

Justice League Unlimited #11

Writer: Mark Waid

Artist: Carmine Di Giandomenico

This issue is a prelude to DC K.O., setting high stakes for the event. The entire Earth is in danger, and everything possible is going wrong, turning the heroes powerless.

Justice League: The Omega Act Special #1

Justice League: The Omega Act Special #1 cover

Writer: Joshua Williamson

Artist: Yasmine Putri, Cian Tormey

Time Trapper discovers the future is already lost, and Earth’s only hope, as always, is the Justice League. And, also: a fun Booster Gold and Wally West adventure!

Aquaman #11

Aquaman #11 cover

Writer: Jeremy Adams

Artist: Nimit Malavia

This issue is totally skippable, as we start entering the realm of tie-ins here. Still, it explains the connection between Darkseid and the Dark Tide.

DC K.O. #1

DC K.O. #1 cover

Writer: Scott Snyder, Joshua Williamson

Artist: Javier Fernández, Xermánico

The event properly starts, and it couldn’t be better. It’s a great buildup for almost everything we’ll see during the tournament, but it already gives us good action scenes with a taste of the chaos about to unfold.

Titans #28

Writer: John Layman

Artist: Pete Woods

While many heroes participate in the tournament, some stay to protect the Earth and the civilians. This dialogue-heavy issue explores how the Titans are dealing with the situation.

Superman #31

Writer: Joshua Williamson

Artist: Eddy Barrows, Eber Ferreira

Williamson’s Superman has been one of the best and most consistent DC runs recently, and it doesn’t disappoint. If you love Superman, you’ll love this issue because it makes the event more personal to him. All of that while setting up more stuff for K.O. and for the run.

The Flash #26

Writer: Mark Waid, Christopher Cantwell

Artist: Vasco Georgiev

If the future is already lost and the heroes are doing everything they can in the present, what about the past? So, Bart Allen has one idea: Impulsepoint. But Flash already knows how bad that can get and runs to stop him.

Justice League Unlimited #12

Writer: Mark Waid

Artist: Dan Mora

The start of a new arc and a step up in quality for Justice League Unlimited. Mister Terrific gathers a group of time-displaced heroes for a mission at the core of the planet.

DC K.O.: Knightfight #1

DC K.O.: Knightfight #1 cover

Writer: Joshua Williamson

Artist: Dan Mora

We know that Batman’s prep time can handle anything, so even death isn’t enough to stop him. However, he wakes up in a strange future, where Dick Grayson is the Batman, and Bruce must fight his way out of it.

Titans #29

Writer: John Layman

Artist: Pete Woods

The evacuation is complete, and the Titans leave Earth, but they all get scattered across space. This issue focuses on Nightwina and Raven as they must escape Gemworld.

DC K.O. #2

DC K.O. #2 cover

Writer: Scott Snyder, Joshua Williamson

Artist: Javier Fernández, Xermánico

Craziness and chaos ensue as the heroes must gather weapons of war to advance in the tournament. It might disappoint those who wanted it to start with the 1v1 fights, but it’s a fun all-out brawl.

Superman #32

Writer: Joshua Williamson

Artist: Eddy Barrows, Eber Ferreira

This issue focuses on what Lex was doing before the tournament and how he got there. We also get a few Superboy Prime scenes, which have been really fun.

The Flash #27

Writer: Mark Waid, Christopher Cantwell

Artist: Vasco Georgiev

Flash keeps running after Impulse, but they aren’t alone anymore. Now, both will have to work together to face the Legion of Darkseid. Waid taps into great character dynamics here, bringing out what’s best about both speedsters.

Justice League Unlimited #13

Writer: Mark Waid

Artist: Dan Mora

Mr. Terrific and his team venture through hell to save Earth. The situation gets more dire by the minute, and some of the heroes might not make it back alive.

DC K.O.: Knightfight #2

Writer: Joshua Williamson

Artist: Dan Mora

Bruce confronts Dick Grayson about his newfound future and what it means to be Batman. But, even if he defeats Dick, there are more Batmans lurking in the shadows.

DC K.O.: Superman vs. Captain Atom #1

DC KO Superman Vs Captain Atom #1 cover

Writer: Joshua Williamson

Artist: Sean Izaakse

If you came to DC K.O. for the hard-hitting fights, then rejoice. Superman vs. Captain Atom is a matchup for the ages, and this issue brings about all of their strengths and history.

Aquaman #12

Writer: Jeremy Adams

Artist: John Timms

The best this Aquaman run has delivered yet! Big surprise: heroes beating each other up is incredibly fun, and Aquaman vs. Hawkman doesn’t disappoint.

DC K.O.: Wonder Woman vs. Lobo #1

DC K.O.: Wonder Woman vs Lobo #1 cover

Writer: Joëlle Jones

Artist: Jason Howard, Cary Nord, Daniel Bayliss

Wonder Woman vs. Lobo enters the tournament for one of the goofiest and most creative fights of the event. It’s a great way to shake things up, and gives this fight another edge besides seeing who’s the most powerful character.

Titans #30

Writer: John Layman

Artist: Pete Woods

The All Fight Month is a huge success for the Titans as well, bringing us another great duel. This time, things are pretty evenly matched, which makes it even more interesting.

DC K.O.: Harley Quinn vs. Zatanna #1

DC K.O.: Zatanna vs Harley Quinn #1 cover

Writer: Leah Williams

Artist: Mirka Andolfo

One of the best things about these fights is how they handle both characters well, and this is a perfect example of that. Even more so, it uses that to build its narrative, making us eager for what’s next.

The Flash #28

Writer: Mark Waid, Christopher Cantwell

Artist: Vasco Georgiev

We get a break from Impulsepoint for another fight. Here we get the usual Flash and Green Lantern duo, but not the ones we’re used to. It’s Jay Garrick vs. Guy Gardner, folks.

Superman #33

Writer: Joshua Williamson

Artist: Hayden Sherman

The first (and last) supervillain fight of the all fight month. Williamson has a great voice for Lex, so it’s always amazing when we get a story focusing on him.

DC K.O.: Red Hood vs. The Joker #1

DC K.O.: Red Hood Vs. The Joker #1 cover

Writer: Joshua Williamson, Scott Snyder

Artist: Dustin Nguyen, Giuseppe Camuncoli, Mark Morales

The final round is also of one the most anticipated fights. Joker and Red Hood’s past gives another layer to their battle. It makes for an emotional, interesting, and compelling chapter.

Justice League Unlimited #14

Writer: Mark Waid

Artist: Dan Mora

Mister Terrific continues his suicide squad-like mission, and the battle against Neron intensifies. One of the members’ fate is sealed, but the show must go on.

DC K.O.: Knightfight #3

Writer: Joshua Williamson

Artist: Dan Mora

Things change even more in this issue, and we get another Batman. But Bruce also finds a clearer path to freedom in what’s one of the best chapters in this series.

DC K.O. #3

DC K.O. #3 cover

Writer: Scott Snyder, Joshua Williamson

Artist: Javier Fernández, Xermánico

And then there were eight. The last remaining competitors face each other in team-up fights, and we get many great match-ups. However, as the Heart of Apokolips’ influence over the heroes gets stronger, the comic raises the question of whether true victory is a real possibility.

Aquaman #13

Writer: Jeremy Adams

Artist: Daniel Bayliss

This issue basically moves away from the DC K.O. event to focus on Mera. New threats emerge with the kingdom of Atlantis, posing a great challenge for the queen.

Titans #31

Writer: John Layman

Artist: Pete Woods

Donna and Roy are Earth’s last line of defense against Grail, Darkseid’s daughter. However, the Titans still have problems on Gemworld, giving Jinx more time to shine.

DC K.O.: Green Lantern Galactic Slam #1

Writer: Jeremy Adams

Artist: Pat Boutin, Cian Tormey

Kyle Rayner also wants to join the fight to save Earth, but he has to go through Omega-Bam-Man and his wrestling shenanigans before that. It’s as goofy as you’d imagine, but that’s what’s so fun about it.

Superman #34

Writer: Joshua Williamson

Artist: Eddy Barrows, Eber Ferreira

Williamson’s Superman continues to be one of the best parts of the event, and it’s Prime Time. Superboy’s voice has only been getting better, and it’ll be a delight once he gets the main role properly in the series.

The Flash #29

Writer: Mark Waid, Christopher Cantwell

Artist: Vasco Georgiev

The Legion of Darkseid keeps chasing our heroes throughout time, and they arrive at one of DC’s most iconic moments: when Barry was first struck by lightning.

Justice League Unlimited #15

Writer: Mark Waid

Artist: Dan Mora, Sean Izaakse

As Neron reveals his plan, and Hell keeps getting more hellish, we also focus on Earth and the Watchtower. The twisted adventure keeps bringing us tension, but it’s also fun to follow the new heroes trying to protect the planet.

DC K.O.: The Kids Are All Fight Special #1

Writer: Jeremy Adams

Artist: Travis Mercer

The Kids Are All Fight Special is inconsequential to the DC K.O. event, focusing on Jon Kent, Cassandra, and some minor characters, like Boom and Cheshire Cat.

DC K.O.: Boss Battle #1

DC K.O.: Boss Battle #1 wraparound variant cover by Jeff Spokes

Writer: Jeremy Adams

Artist: Carmine Di Giandomenico, Ronan Cliquet, Kieran McKeown, Pablo M. Collar

Boss Battle has to be another highly-anticipated issue in the event. Although it could’ve been longer, it was fun seeing the DC characters interact with the likes of Homelander, Red Sonja, Annabelle, and more.

DC K.O.: Knightfight #4

Writer: Joshua Williamson

Artist: Dan Mora

Knightfigh is a series that shines brighter every chapter, reaching an emotional and incredible conclusion. It’s definitely a top-three contender for best run in this event.

DC K.O. #4

DC K.O. #4

Writer: Scott Snyder, Joshua Williamson

Artist: Javier Fernández, Xermánico

With only four competitors remaining, three new fighters join the tournament. It’s time for the DC heroes to meet the Absolute Universe.

Aquaman #14

Writer: Jeremy Adams

Artist: Daniel Bayliss

The run moves away further from the DC K.O. events to focus on Andrina and Mera.

Titans #32

Writer: John Layman

Artist: Pete Woods

The last issue of Layman’s Titans run. It continues the previous story while setting up the next series with Cheshire Cat and other newer characters.

Superman #35

Writer: Joshua Williamson

Artist: Eddy Barrows, Eber Ferreira

The last issue for this arc, and, again, Prime and Lois Lane are incredible. It’s a great build-up for Prime’s story, which will start next issue.

The Flash #30

Writer: Mark Waid, Christopher Cantwell

Artist: Vasco Georgiev

Flash and Impulse’s race takes them not only to a past Darkseid, but to Waid’s last issue in this run. From issue #31, Ryan North takes the helm, and it’ll surely be a fun time.

Justice League Unlimited #16

Writer: Mark Waid

Artist: Dan Mora

All the plots converge, and Mister Terrific and his team finally confront Neron. But they must find the traitor in their midst before they can win their final battle.

DC K.O. #5

DC KO #5 page 2

Writer: Scott Snyder, Joshua Williamson

Artist: Javier Fernández, Xermánico, Wes Craig

The final chapter of the event is here, and the last fight is as huge as you’d expect. It’s a grand finale, but also a setup for many new stories.
