Michael Waldron Reveals Which AVENGERS: DOOMSDAY And SECRET WARS Character Has Been Most "Fun" To Write

Avengers: Doomsday writer Michael Waldron has named the character he's had the most fun writing while working on the movie with Stephen McFeely, and it's someone many fans can't wait to see on screen...

Stephen McFeely and Christopher Markus collaborated on several Marvel Studios movies, including Captain America: Civil War, Avengers: Infinity War, and Avengers: Endgame

Original plans called for Jeff Loveness to write Avengers: The Kang Dynasty, with Michael Waldron penning Avengers: Secret Wars. Now, Loveness is out, and McFeely is teaming with Waldron to end the Multiverse Saga on a high note. 

During a recent Reddit AMA, Waldron was asked which character has been the most fun to write while working on Avengers: Doomsday. His answer? "Doom."

Robert Downey Jr. will play Doctor Doom in the next Avengers movies, and has so far only been glimpsed in The Fantastic Four: First Steps' post-credits scene. We know relatively little about what to expect from Victor's story arc, or whether Doom will play multiple Variants of the villain. That had been the plan for Kang, of course, and there are heaps of exciting possibilities if the same holds for this Saga's new big bad. 

As we first reported yesterday, during this same Q&A with fans, Waldron shared some insights into his and Loveness' approach to their Avengers movies before Kang was swapped out for Doom. 

"Jeff Loveness and I spent an afternoon pitching on the Young Avengers defeating a version of Kang and being so stoked about it," he explained, "only to discover that that particular Kang carried a little card that said to 'Be Patient' with him, it was his first day as a Kang."

"And then they were so bummed," the writer added. "I think he was gonna be the lizard Kang from the end of Kang Dynasty? I don't know. Anyway we had fun." 

Waldron and Loveness are best known for their work on Rick and Morty, so they'd have likely brought a lot of comedy like that to The Kang Dynasty and Secret Wars. Loveness wrote Ant-Man and The Wasp: Quantumania for Marvel Studios, while Waldron penned Loki Season 1 and Doctor Strange in the Multiverse of Madness.

I trust him and after Christopher Markus leaving the duo (who is the better writer imo) they needed someone. I guess it'll work? Who needs an ending muahaha

Not really shocking since Doom is just a great character in general…

It’s always more fun to write the villain , especially someone who is likely as egotistical as Victor is.

Anyway while I have my long term concerns about RDJ’s casting , the man is a fantastic actor and I’m sure will do well bringing the version of Victor that’s on the page to life (hopefully the character is written well which I have faith he will be)…

Personally I hope Doom is no nonsense , serious & humorless.

I’m sure RDJ has rewritten most of his scenes anyway so it shouldn’t matter anyway.
