Re: IM4 in Phase 3?
For IM4, I'm thinking a fusion of the "Demon in a Bottle" and "Armor Wars" story lines...
Perhaps a new weapons manufacturing company starts mass-producing armors very similar to Iron Man armors for military use, while Stark Industries begins struggling and it looks like Tony's company might be going under. On top of all this, Tony's armors are malfunctioning while he's wearing them and even end up causing an innocent death. Tony starts beating himself up about this and begins binge drinking and falling deeper into alcoholism.
In the end, it turns out that Hammer has secretly returned and is behind all of this. Ghost, Madame Masque, and maybe another villain are in his employ, and Rhodey and Pepper eventually figure all this out while trying to get Tony well again.
Of course, Tony recovers and wins the day through some super geniusing.
What do you guys think?
