DC K.O. Justice League Unlimited
Mr. Terrific and an elite Justice League squad embark on a do-or-die mission to unravel the mysteries of the epic DC K.O. event!
As the tournament for the fate of the Earth heats up, Mr. Terrific assembles an elite Justice League squad—chosen from the time-displaced heroes from "We Are Yesterday"—to face a threat hidden within the planet’s core! With the rest of the League occupied by Darkseid’s brutal battle for the role of King Omega, and the Watchtower under siege from fearsome parademons, only Michael Holt and his hand-picked heroes stand between humanity and the demonic Neron!
It’s a mission to Hell and (hopefully) back from the pages of Justice League Unlimited #12-16, from the superstar team of writer Mark Waid and artist Dan Mora!

About the author
Mark Waid
3,253 books1,348 followersMark Waid is an American comic book writer widely known for shaping modern superhero storytelling through influential runs on major characters at both DC Comics and Marvel Comics. Raised in Alabama, he developed an early fascination with comic books, particularly classic stories featuring the Legion of Super-Heroes, whose imaginative scope and sense of legacy would later inform his own writing. He first entered the comics industry during the mid 1980s as an editor and writer for the fan magazine Amazing Heroes, before publishing his first professional comic story in Action Comics. Soon afterward he joined DC Comics as an editor, contributing to numerous titles and helping shape projects across the company. After leaving editorial work to focus on writing, Waid gained widespread recognition with his long run on The Flash, where he expanded the mythology of the character and co-created the youthful speedster Impulse. His reputation grew further with the celebrated graphic novel Kingdom Come, created with artist Alex Ross, which imagined a future DC Universe shaped by generational conflict among superheroes. Over the years he has written many prominent series, including Captain America, Fantastic Four, Daredevil, and Superman: Birthright, bringing a balance of optimism, character depth, and respect for comic book history to each project. Waid has also collaborated with notable artists and writers on major ensemble titles such as Justice League and Avengers, while contributing ideas that helped clarify complex continuity within shared superhero universes. Beyond mainstream superhero work, he has supported creator owned projects and experimental publishing models, including the acclaimed series Irredeemable and Incorruptible, which explored moral ambiguity within the superhero genre. He later took on editorial leadership roles at Boom Studios, guiding creative direction while continuing to write extensively. In subsequent years he expanded his involvement in publishing and digital storytelling, helping launch online comics initiatives and advocating for new distribution methods for creators. His work has earned numerous industry awards, including Eisner and Harvey honors, reflecting both critical acclaim and enduring popularity among readers. Throughout his career Waid has remained a passionate student of comic book history, drawing on decades of storytelling tradition while continually encouraging innovation within the medium. His influence extends across generations of readers and creators, and his stories continue to shape the evolving language of superhero comics around the world today through enduring characters imaginative narratives and thoughtful reinventions of familiar myths within popular culture and modern graphic storytelling traditions.

A fun tie-in to the big KO event. I liked seeing the alternate heroes and how they accepted their fate.
August 31, 2026
I wanted to give this book 3.5 stars, it is a bit chaotic, and what was a bit dissapointing for me was I am a big fan of a lot of the the Terrific Ten and I wanted them to have more time each which I really don't think they got.
Darkseid is destroying the DC universe, past, present and future. While the what is left of the Justice League (those not in the tournament) are evacuating the Earth. However some villains are still out for themselves and have made a deal with a devil. The only hope is the time displaced, and dying Terrific Ten to literally into hell to take the fight straight to the devil.
This book has a high casualty count. Not everyone (or anyone) is getting out alive. Thus book will show what it means to be a hero. A good book, I wish it was longer and more characters had a chance to shine. The book finishes with a variant cover gallery.

Leído en números individuales.
Waid vuelve a introducirnos a los personajes como en el primero de los arcos en el número #11. Ahora hay variantes de los personajes de pasado, presente y futuro. Con los villanos de pacotilla ganando poder posiblemente por un trato con Neron, Mr. Terrific junta a un equipo para contrarrestarlo. ¿Conozco a alguna de las variantes? En realidad, no he leído mucho de ellos, pero cómo molan.
Entonces, Mr. Terrific muestra lo que ha descubierto a lo largo de los dos arcos anteriores: las versiones de los personajes que tenemos no son más que reminiscencias de sus líneas del tiempo originales. Si DC K.O. sale bien, van a desaparecer. Lo que le daría una oportunidad de usarlos como personajes dramáticos bien construidos. Y, de repente, Waid nos lo da en unas cuantas páginas. Maravilloso. De repente, el lector empatiza al momento con esas versiones de Guy Gardner y de Aquaman.
En el #12, Mr. Terrific lleva a sus compañeros al infierno. En el segundo de los números, ya demuestra por qué los ha llevado: son, técnicamente, sacrificios. En la primera de las pruebas, ya perdemos a Guy y a una versión de Kara que es Power Girl… cortada por la mitad. Después, vemos qué ocurre en la tierra, pero me parece menos interesante. En el infierno, el joven Batman/Tim Drake está aterrorizado. Al parecer, es nuevo. Alan Scott le dice que están en una misión y que espabile. Superman es, por supuesto, empático. Alan acaba salvando a Batman y se convierte en otro sacrificio.
En el #13, de este Escuadrón suicida llamado “The Terrific Ten”, ya quedan solo 7: Doctora Fate, Aquaman, Batman, Superman, Owlwoman, Gold Hawk y Mr. Terrific. Se encuentran con Caronte y para montar en su barcaza, tienen que dar algo que les importe mucho. Quien más pierde es este Superman, que tiene que dar su capacidad para sentir la esperanza. Muy potente. La trama de la tierra me interesa menos, pero imagino que es para justificar que la misión es importante por el poder de los villanos gracias a Nerón. De nuevo, este número nos da otra muerte: Aquaman. Y, entonces, eran seis.
En el #14, por fin la trama de la tierra es más interesante porque vuelve Air Wave. Al parecer, los problemas eléctricos que estaban teniendo era por su culpa, tratando de comunicarse con la Atalaya. Entonces, guía a algunos miembros que no conozco de la Liga a Costa Rica para luchar contra la Legión de Nerón. Entonces, aparece un ¿holograma? del demonio amenazándoles. Volvemos entonces a nuestros suicidas particulares.
En el #15, Superman se sacrifica para acabar con otros de los monstruos del infierno. Por cierto, Mora dibujándolos está de diez. De repente, vamos perdiendo a la velocidad de la luz a cada uno de los que nos quedaban: Batman, que está enfrentándose a la idea de tener miedo y reconocerlo, se sacrifica para salvar a la Doctora Fate de un Gold Hawk poseído (que acabará muriendo también). En las puertas de Nerón, también mueren la Doctora Fate y Owlwoman. Y solo queda uno: Mr. Terrific. Este le ofrece a Nerón a sí mismo: es el hombre más inteligente de la Tierra. Nerón parece escucharle pero, de repente, descubrimos que había un traidor entre los diez: Owlwoman. Efectista, previsible. Es uno de los pocos personajes con los que no habíamos empatizado. Pero, oye, funciona.
La trama termina en el número #16. Explica Owlwoman que traicionó al equipo porque Mr. Terrific les explicó que eran fantasmas cuánticos que prácticamente no existían. Y ella no quería morir. Entendible. Al principio, parece que Nerón va ganando. Eso se muestra también en la tierra, donde el equipo de la Liga tiene muchos problemas. Owlwoman los ve, sin entender por qué siguen luchando si ya han perdido. Nerón la manda a luchar contra ellos y entonces es cuando ella la traiciona. Se sacrifica permitiendo que todos los demás escapen. Tienen que ir a la zona fantasma, ya que la tierra está perdida. El final pega duro, cuando Mr. Terrific comentó a sus salvadores que había un traidor en el grupo, pero cuando le preguntan cuál es, dice: «ir doesn’t matter. What matters is that they all died heroes».
El arco es autoconclusivo, en realidad. Nos da un nuevo grupo de héroes que sabemos desde el primer momento que están condenados a morir, ya sea por la misión suicida o porque los héroes ganen el torneo de DC K.O. Aun así, poco a poco se va empatizando con cada uno de ellos. Como crítica, diría que habría disminuido el número del equipo y hubiera alargado la primera muerte para que hubiera más impacto emocional. Algunas han quedado muy deslucidas, como la de Guy o la de Gold Hawk.

(Read in single issues). On reflection, I really like this volume of JLU that goes on at the same as the events of DC KO. That mini-series is written by Scott Snyder, and Waid here fortunately doesn’t play in that sandbox. Rather, the volume covers what's instead happening on Earth, while all the JL heavy hitters (Superman, Batman, Wonder Woman, etc.) are off fighting in Darkseid's tournament off-planet.
That's a good choice for this book as it makes good use of the 'Unlimited' roster of the Justice League, which is the premise of this title. And, this volume cements the potential of this title for me, in that regard.
The story follows two teams of Justice Leaguers, that confront augmented-villians that are taking advantage of the calamity on Earth and are committing widespread crimes. The villians have received the power-ups from the Devil/Neron, so one team, headed by Martian Manhunter, confronts the criminals while the other, lead by Mister Terrific, travels to Hell to stop/confront Neron. The team lead by Mister Terrific are the time-displaced Leaguers from the previous volume of JLU, so this volume picks up from the last.
It's a real treat, once more, to spend time with time-displaced Leaguers, who are plucked from DC's publishing history. There's Peter David's one-armed Aquaman, Electric-Superman, Batman Beyond/Tim Drake, Owl Woman (an alternate version of Watchmen's Owl Man), and others. Waid gives life to them, and when it's otherwise established they are really shades or time-remnants with no real future. They still have their own motivations though, and this matters to the story's end, which I really liked.
I also liked spending so much time with Mr Terrific - he's a great leader and character as written here hy Waid, but I haven't read any of his other appearances, in Johns' JSA or Lemire's The Terrifics, to know. These JLU DC KO issues give Terrific a leading focus, and it is pretty great.
Dan Mora is on art, and while the flitting between combat in Hell and on Earth can get a little muddled, the art is still solid enough (that and Mora must be drawing the equivalent of three monthly books at this time - his output's incredible, but maybe it's a little rushed than might otherwise be the case. Still, good enough though).
With this volume, JLU has cemented its place for me, as a title to look forward to reading every month. I'm very happy with the writing.

While the rest of the Justice League are stuck in the King Omega tournament, Justice League Unlimited sends Mister Terrific to Hell, with his new friends the time-displaced remnants from We Are Yesterday as his companions.
I like what was attempted here. There's a nugget of really good ideas, and the stretch on Mister Terrific's morals is interesting to watch play out. It's the stakes that bother me. We're repeatedly told that the time-displaced remnants aren't even 'real' in any sense of the word, so when they all inevitably get picked off as the story progresses, it's hard to care. There's still the world at stake thanks to Neron, but it saps a lot of the character drama at the same time, and I can't help but think that this arc was just Waid spinning wheels until KO was over.

The KO battle for Earth continues...
(poorly for the JLU)
Above? The League is left with mid-tier heroes facing powered up third string villains.
Below? Mr. Terrific takes a team of time displaced heroes to confront an ambitious Neron.
Feels like a time travel version of Suicide Squad. Everybody was told they're irrelevant.....and GO!

Bonus: Batman Beyond (Tim Drake) cameo? Hahaha

The rest of the heroes not involved in K.O. try to evacuate the earth while some villains make a deal with Neron and cause problems. Meanwhile Mister Terrific assembles a team of heroes from other times and universes to descend into Hell and stop Neron. It's not bad.

This run, already being weak, did not need this tie-in. This is an extremely forced, unnecessary, and boring arc that didn't need to exist, and I'm disappointed I had to buy and read it. I really hope this run picks up after this.

MISTER TERRIFIC... *heart eyes*

There’s a big event so Waid gets to play with some old toys in a story that is a side quest. And player does. Extra points
For pluck.

Review of advance copy received from Publisher
Mark Waid is one of the best to ever do it, no argument. But this series was already a little unfocused and the event tie-in doesn't help matters. And using the Tim Drake version of Batman Beyond in this? That's a troll move.
