Iron Man, Wolverine & Venom Get New Costumes in Dark Avengers Concept Art

screenrant.com:

In concept art recently shared by Mike Deodato, the Dark Avengers' original designs reveal that Norman Osborn almost wore very different Iron Man armor as the team's leader, and that the designs for the twisted versions of Wolverine, Venom and more could have been totally new.

As part of Marvel's Dark Reign event, Norman Osborn (the former Green Goblin) was able to use the Skrull invasion of Earth to elevate himself to a position of power while destroying trust in the planet's heroes. With many heroes still on the run due to the Superhuman Registration Act, and Tony Stark disgraced by his inability to stop the events of Secret Invasion, Osborn formed his own team of Dark Avengers — villainous characters who were happy to pose as iconic heroes.

Appearing in Dark Avengers #1 by Brian Michael Bendis and Mike Deodato, the team was originally comprised of Sentry and Ares (prior Avengers associates willing to work with Osborn) as well as Wolverine (Logan's son Daken), Hawkeye (Daredevil villain Bullseye), Spider-Man (Mac Gargan's Venom), Ms. Marvel (twisted psychiatrist Moonstone), and Captain Marvel (the alien terrorist Noh-Varr.) Osborn rounded out the team in a modified Iron Man suit, attempting to combine the imagery of both Iron Man and Captain America as the twisted Iron Patriot. Of course, central to the ruse was the idea that the team looked like the classic Avengers, so it was ultimately important their costumes remained as similar as possible to the originals. However, past comics have included original concept sketches which show the villains in unique uniforms, suggesting there was a time where they'd have had distinct 'heroic' looks
