About the author

Mark 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.

Reviews

This was a bit all over the place like its taking place after the crossover but it also ties into DC KO like it shows the heroes who were pulled over from diffeent point of time streams and whats going on for them and their mission like time ship and all, a fun story with how they save Air wave and then love the mentor-mentee relation between Mr Terrific and Air wave and love how he is taking over the leadership of the team.

Then they have to deal with evil legion and omega demons or whatever you call it across time stream and yeah its confusing as I am writing it.. I dont even recall what it was even having read it.. the story is just a mess like the overall thing with what he is doing here and turned me off from reading this book in the first place.

But then there is the story in the omega act special with Doomsday taking Booster Gold and Wally to show how the future is being destroyed by Darkseids legion and we get an interesting retcon with how Doomsday was made to be a weapon against Darkseid or something.. yeah weird retcon but Josh has talked about it.. I guess we will see more of that in the future. It was fine overall a fun issue.

This run is weird honestly, you can read the DC KO event without having read this.. honestly skip this run.. its just bad.

This second volume of JLU is a little transitory - it acts as both an epilogue to the We Are Yesterday crossover as well as a prelude to DC KO, which makes it a little difficult to judge on its own merits.

We get 3 issues of JLU itself, which pull on some threads from Joshua Williamson's Superman run and even as far back as Dark Knights: Death Metal, as well as the Omega Act Special, which sets the stage for KO, and the Dark Tomorrow Special which seems to be setting up something else that we haven't seen play out elsewhere just yet.

Each story alone is fairly solid, but as with any collection of this nature, you're not getting a full story. It's kind of essential reading for what came before and after, but if you're not interested in any of that, I expect your mileage may vary on this one.

This is all about the lead up to K.O. The issues leading up to it aren't as dumb as the event itself sounds, with heroes and villains fighting in a ring to be King Omega. This is all about time being out of control due to Grodd messing with it in We Are Tomorrow.

Epic and fun

[Straw Boy · Rating 5 out of 5]

What a crazy cliffhanger at the end. I love the All In series and I need to read every book from this line!

[Keegan Schueler · Rating 4 out of 5]

Wish I read this before DC KO because this was a really good setup for that. Lot going on but DC fans will eat this up.

[Olivia · Rating 2 out of 5]

it’s so boring.. gorilla grodd is cool but there’s so much stuff happening at once it loops back to being just generic and lame

[Sesana · Rating 3 out of 5]

Another volume that's just setting up the next event.

[Daniel Butcher · Rating 4 out of 5]

Lots of hitting and prequel to a big event.

I can see the layers in play, and I think I’ll like it.

Another vol of set up for the next event. While I don’t mind, now I feel I’m missing out by not reading JLR & Superman immediately even tho I’m waiting for the trades. When before it felt everything close enough like with the atom project. I understand with how this run has been so far but Im looking forward to K.O
