I've really only picked up the Avengers figures from both Legends and Marvel Universe, but I've expanded that over the years to include a few characters from the old days or who have just had regular involvement with the team. I wouldn't normally call Captain Marvel, Hulk, or Beast part of the Avengers, but I picked them up anyway. I've spent a good deal of ca$h on figures they never made, like Sersei, Crystal, Mockingbird, Starfox, Giant Size Cassie Lang, and Kate Bishop and I have upgrade customs of Tigra and the 80's Black Knight with his winged horse.
There aren't too many more characters I want to add, but I will still pick up a few of these. I have a 6" Hall of Armors display for most of the Iron Man figures, so I would probably nab him and the Stealth variant if I like them. Commander Rogers would be interesting too, though I only include one of each character in my display and not sure I want to replace Cap. I'd probably snag Thor too - depends on how much I like them when I finally see them. I certainly wouldn't be opposed to uprading some of my existing characters if they're even better this time around.
Anyone else getting these? How about the Avengers movie figures? Much as I like the Avengers, I think I'm going to pass on the movie line.
