He's an Anti Hero

@SuperSomebody some times hero in king of black venom saved earth from knull

Will not join the X-Men and ride solo

He'd be easily persuaded by Darkseid

He's be a hard working man on his inventions

He's help the X-Men

yes

He'd make a huge sacrifice at the end of an avengers movie

He's be the defender of reality

Well, she's been both good and bad to some extent, so we don't have to imagine much there.

He would have the same motive as General Zod from the DCEU

Evil Superman has happened plenty of times before

Iron Man would be the useless person in the team

What?

With Doom's Prep, Intelligence and armor Iron Man will not be needed.

Oh I get what you mean now
You think he would join the avengers?

Maybe, or create his own avengers and in a comic, the 2 teams will battle, maybe I should create a battle about it.

Oh like his own Thunderbolts, but actually good. That would be cool. It could be with all the partly good villains, like Loki, Magneto, and Venom.

Doom already formed his own Avengers in Avengers World 3. US Agent is on that team and so is Elsa Bloodstone. 3D Man is in there and some other people

Yes I've read the comic, but aside from Doom himself it was a fairly underwhelming team. That team certainly couldn't defeat the main avengers without Doom.

He'd kill people and drink

You aren't wrong

He would try to kill the Avengers, starting with Thor, but would lose because of either Wanda, Tony, or another team coming to help. Then Reed Richards would find a way to permanently deal with him.

Thanos (Infinity Gauntlet)

He would kill the JLA

Ha, good Darkseid would be great, he would just destroy anything evil

Let's call him "Lightseid"
