== The Mark 22 (XXII), also known as the "Hot Rod", is a War Machine 2.0 Prototype Suit, and was one of the many newly built suits created by Tony Stark, sometime after the events of The Avengers.
It was featured in the movie Iron Man 3, and made it's debut in the movie when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol", in which it was activated along with all the other suits to aid Tony in his battle against Aldrich Killian.
The suit earned it's name the "Hotrod", because of its flame like custom design on it's arms and legs plates, which is where it's name is derived from, because of it's appearance that resembles that of a "Hotrod". It was made to have the same defense as the first war machine suit, but with 1/3 of the weight. == War Machine 2.0 Prototype Suit 他是 WM mk2 的原型衣耶 改良變 1/3 的重量相較之前的 WM mk1 怎麼會是 WM mk2 的改良版 這說法我是第一次聽到
