Injustice vs. Masters of the Universe, by writer Tim Seeley and artist Freddie E. Williams II, is an action-packed limited series that's overflowing with fan-service. With three issues already released, it's beyond obvious that Seeley's been having a total blast playing around in the sandbox with all of these classic characters and making them clash. There has already been plenty of brawling -- like He-Man taking on some of DC's most dangerous villains, including Deathstroke, Lobo and Cheetah -- but the writer promises that the best battles are still on the way.

Injustice vs. Masters of the Universe #3 ended with Injustice's Superman finally meeting He-Man. It's the moment that fans have been waiting for, as the no-holds-barred version of the Man of Steel rushed at He-Man and blasted the hero with heat vision. The two are about to duke it out, and Seeley promises the fight will deliver big time. While chatting with CBR at New York Comic Con, Seeley called the upcoming issue "one of the coolest things" he's ever written.

"They meet and the brawl is on," said Seeley. "It's a one-issue fight scene between them, but it switches back and forth to the invasion of Eternia from Darkseid and Apokolips, so it's parallel fight scenes. I'm so proud, it's one of the coolest things I've ever written and Freddie's doing the coolest art of his career."

Seeley continued to talk about the upcoming issue, assuring fans that the collision between the cruel Kryptonian and the Most Powerful Man in the Universe won't be over quickly.

"I feel like four is the climax," said Seeley. "It's like a big high point, it's the thing we promised. It's Superman versus He-Man and there's no misunderstanding, and these are two dudes that genuinely disagree and they totally hate each other and they brawl for 22 pages."

Superman versus He-Man isn't the only thing fans should get excited about, though. Seeley was excited to tease Darkseid attacking Castle Grayskull.

"There are cool matchups going on," said Seeley. "My favorite thing in this whole series is Darkseid goes to Grayskull and he's like, 'I want in.' Grayskull's notoriously impenetrable in Masters of the Universe. You have to have the swords to get in, and it's Darkseid versus Castle Grayskull, basically. He's like, 'I'm getting in. I don't care what you are, I'm Darkseid.' And so it's just like basically the thing you always wanted to play when you were a kid."

Seeley would love to write more with Masters of the Universe and the DC cosmic scene as well.

"Man, I'd love to do another Masters of the Universe one," said Seeley. "One of the things we talked about was Masters of the Universe versus The Fourth World. You know, bringing in Mister Miracle and Orion."

The writer says the ending of this limited series could justify bringing more of the Fourth World into a sequel.

"We set up some stuff at the end of the series -- I won't give it away -- but there's a little thing in there that we could totally get away with," said Seeley. "We could have a reason to go to Apokolips and we could have a reason to bring in all this stuff, so it would be cool. I'd love to do it."

Seeley mentioned there's another upcoming fight sequence in Injustice vs. Masters of the Universe #4 that he's especially enthusiastic about. In fact, he liked it so much that he said he's going to buy Freddie E. Williams II's original artwork of the scene.
