9. "Iron Man" (Mark 1, cave suit).

As far as suit ups go, this one isn't too exciting. Although I DO really enjoy the suit itself for it's "realness."

8. "Avengers: Age of Ulton" (Hulkbuster).

When the Hulkbuster was first revealed to me in a trailer, I thought it would be its own suit, but the fact that it was more of an attachment to other suits lowered its cool ranking.

7. "Avengers Infinity War."

Nanotech is neat, but I think they went too far with this one. It looks like the suit is defying physics by creating matter from nothing. Although, like Mark 1, I really like the suit as a whole.

6. "Captain America: Civil War."

I really liked a lot of this suit up except how it was executed. I mean, just a button? Really? If that was me I'd hit that so many times by accident.

5. "Iron Man 3" (final battle).

Tony goes through SO MANY SUITS in this scene, but the way he goes from suit to suit to suit to suit is so slick. Some were cooler than others, but it was still neat to see so many.

4. "Iron Man" (Mark III). 

While this suit isn't as flashy as his new ones, the way he suits up in it feels so doable. We see pieces getting hooked and connected. I could see Elon Musk having one of these set up in his basement...

3. "The Avengers" (Mark VII).

The clip I linked is like a twofer. We see a cool un-suit then an AMAZING suit up as Tony is falling to his death. Only complaint... I feel like he fell for an unreasonable amount of time... but it's not like this is the most real of real universes we live in.

2. "Iron Man 3."

I loved this particular suit up for Tony's humor and the way the pieces just flew to him in the ways that were also usable by themselves to a certain extent.

1. "Iron Man 2."

I have loved this suit since I first saw "Iron Man 2" in the theaters. The idea of a travel suit was cool and done really well. We see the suit is almost skeletonized with fewer gadgets, which makes sense having it be for travel. Plus it still looks almost doable for the size and way he put it on. 10 outta 10.
