Iron Age Alpha 1
I’m not sure if this is heading for a crossover or miniseries or what, but the setup has decent plot potential. A dying mad scientist with a grudge against Tony Stark kidnaps him and makes him watch as he uses one of Doctor Doom’s time machines to somehow pluck Dark Phoenix out of time. He provokes her and Tony gets to see her destroy the Earth – but he also gets thrown back in time, so I assume the rest of the story is Iron Man gathering forces to somehow prevent this.
