5. The Model 16

God, Heroes Return was fun.

And it spawned an Iron Man run that was way better than anyone acknowledged. The glowing head and neck pieces just looked cool! As did that sharp-edged mask. He just looked great – can we get this one back sometime soon? Tony wore the suit for a while, and had some good adventures. These include:

• The formation of the Heroes Return Avengers team
• His battle against Ultron’s resurgence
• His work to stop Baron Zemo and the Thunderbolts from taking over the earth
• His team-up with Carol Danvers (Ms. Marvel at the time) to fight off the Kree
• The Mandarin’s return to the forefront

Also, this suit kinda sorta came to life and decided it was in love with Tony Stark. Yeah, that’s a thing. Creepy stalker armor was a great storyline, check it out if you get any amount of time.

But yeah, Stark eventually had to abandon this suit when its power source became too toxic.
