Man something I didnt realize, Im actually reading the Dark Reign Saga comics right now. Funny this Event started and Im on the Hulk issues. This is actually leading me to some interesting possible characters that should be introduced.
Seems during Dark Reign Red Hulk caused Hulk to loose his powers somehow, so Red Hulk should be there. Because Hulk lost his powers, Its now Bruce Banner. While he's stuck in Puny Human form, he's training hulks son, Skaar. So Definitely He should be in there. So many potential variations of Hulk that could be put into play.
If you can, read The Incredible Hulk 603, Thats a particularly amusing issue. Banner and Wolverine swap parenting tips while Skaar and Daken make friends. The ending made me laugh so hard.
I know this is "loosely" based on the dark reign saga, but lots of things are missing. Iron Patriot and Sentry are the top 2, but I had totally forgot Osborne made a Dark X-men as well. Emma Frost was leader & also part of the Cabal, as was Namor. I really feel the villians are lacking, especially with a new Thor being released. Also finding out Thor is mostly MIA during Dark Reign as well since he was banished from Asgard thanks to Loki.
The game has really led me to read the comics again. In order to get to dark reign though youd have to do a quick recap from Civil War, into Secret Invasion, then to Dark reign sagas respectively. The marvel Universe is so vast!
