Pardon my ignorance, but I figure this is as good a chance to have a burning question I've wanted to have answered. What exactly is the difference between the Mark III (from the end of IM) and Mark IV (seen at the beginning of IM2)?? I see only very subtle design differences when comparing the pictures. Until I started reading information about the film, and the toys when IM2 came out in 2010, I had no idea there was a difference other than perhaps how the suit assembles on and off Stark's Body? We never saw Stark put the mark VI on at the end of IM2, so I guess the platform on top of Stark Tower in Avengers is as good as any. Its been a long time since I've seen IM, but the only explanation I can think of is the Mark III was damaged beyond repair at the end from the battle with Iron Monger? -I know in the comics Stark has a hall of Armors (or at least he used to, could be something different now). He collects them like cars I guess. A different one for different purposes, some functional, and others not. Although seeing the mark VI underwater shows he didn't decide to abandon it after the damage it took at the end of IM2. I guess he dosen't always dispose of his suits after one battle. It just all feels kind of randomized what circumstances in the Movieverse motivate Stark to build new armor as opposed to repairing and upgrading already existing ones.
The Mark V is fun, and the Briefcase is great for old school comic fans. I went with the Mark VI however it seemed to have the coolest selection of weapons. I applaud the writers for not making IM outshine the rest of the Avengers too much, but I was hoping to see at least one cool weapon on the Mark VII that we hadn't seen before. I'm just hopnig to see a Hulk Buster in a future marvel film.
There has never been a "Scientifically Accurate" Dinosaur portrayed on any Television Show, Movie, or Documentary. Only what the human imagination can conceive, and I'm ok with that.
