In the aftermath of the zombie plague, Justin Hammer has been getting quite a lot of positive media spin. He is the (co?) creator of the cure, and a very public face in the rehabilitation of America. He's been donating his money, time, and supplies to the clean up efforts, and helping work with S.H.I.E.L.D. and the government to set up food rations stations etc.
Nick Fury, on the other hand, has been suffering quite the image drop. The council will soon have him up on public charges for what took place in Genosha. Justin, will at that time, testify to both the Genosha incident, as well as provide evidence to the other offenses Nick has committed, such as the orphanage incident.
Nick will be deposed, and (likely) escape/go into hiding. Hammer is put in his place as Director of S.H.I.E.L.D. because of his recent humanitarian work in conjunction with S.H.I.E.L.D., previous and continued primary weapons supplier contracts with the US. military, and general public persona. (And because comics, that's why, Osborn got the job with less credentials and more crazy.)
Once Justin is in charge:
One of Justin's first acts will be to proclaim that vigilante justice, such as Nick Fury had been trying to measure out on his own, can not be tolerated. He will ask that all the various super powered vigilante groups either disband, or continue to work under S.H.I.E.L.D. supervision, so that they can be held responsible when such things happen. He may or may not did up information on previous things the Avengers/X-men have done which would prove this point. If your characters are involved and you would, or would not like Justin to know something that is not general public knowledge, please say so. Assuming the Avengers refuse (Do they wish to refuse?) Justin would declare them outlaws. He would leave the offer standing that any who wish to leave the group and work under him will not be prosecuted.
The Dark Avengers:
The world still needs super heroes, and Justin would prefer them to be his men(/women). Since he assumes most of the real Avengers will refuse him, he intends to build his own team. Many will likely be on the cusp of the good vs. evil scale. All(?) will be under the guise of current or former Avengers. Whether the public believes these to be the actual Avengers they are portraying, I do not know. Thoughts?
IC these character will approach, bribe or otherwise have to convince Justin, or be convinced by Justin. OOC if you want to be a Dark Avenger, you will be, with 99% certainty. The Dark Avenger (just called Avengers, or New Avengers IC) will function on the surface as the previous ones. They fight the good fight, pose for photos, kiss babies, etc. They primary task will be to hunt down the vigilantes who would not submit, namely the Avengers, and possibly X-Men.
However, behind the scenes, they are very much encouraged to do what ever it takes to get the job done. Certain people need to be put out of the way, etc. etc.. They are very much Justin's tool to further his own needs. And being primarily not....typical heroic people, I imagine sometimes they will take things too far on their own as well. I'm happy to work with whatever ideas you've got, just remember, Justin's concern is himself, and making sure he looks good. So he's not going to tell you to go kick puppies and blow up buildings. It doesn't mean it can't happen, it just means it is not what you will be instructed to do.
Characters:
So far a few people have showed interest in joining. Tony- Double/Triple agent? As Iron Man? Or as 'Justin as Iron Man' Idek. Harleigh will explain. Li Hua- Possibly taking on the guise of Wasp or Tigra Mystique?- Possibly under the guise of Black widow Loki- Possibly under the guise of Scarlet Witch
Registration
Under the same line as his declaration against vigilante justice, Justin may propose super-powered registration. This would effect mutants, super humans, mutates, etc. If the interest is there I will push it forwards, if people would rather it not happen, I won't. The End? I...don't know exactly how/when it will end. I assume you lovely people will over throw me. If you're really stuck I can shoot out ideas, but lets see what you've got first.
This is all just my initial thoughts. Please, if you have any questions, concerns, disagreements or ideas, say so now so we can plan this together to be the most fun for everyone.
