It's my fave Iron Man armor. Loved that call back to heroics look while looking a bit more advanced than anything else. Streamlined, but just enough heft without going overboard.
I was more than a bit hurt when he had to replace it with the SAFE armor. Even if it was pretty much the same design.
Ock vs Iron Man would be pretty interesting at this point. It might've been better if Ock decided to "go legit" and just restart a company to rival and beat others instead of languishing around as a maybe villain maybe anti-hero since the clone stuff.
