Ironman Mark I was created during Tony Stark was held hostage by the terrorist group. The suit was made by whatever limited resources there were in the cave. That's why the suit was very crudely done, and looks raw. Hot Toys has done an excellent job replicating the suit in the movie.
The detail of this figure is amazing, and it is great workmanship that how Hot Toys put all these parts together! The armor are made out of crude iron panel pieces, wiring, coil, gas tank, wheel tracks, arc reactor, flame thrower ... etc. There are also electronic light up mechanism implemented into the arc reactor and the left arm missile launcher. Underneath the armor, the figure is wearing a green T-shirt cover with a brown outer jacket with brown pants and shoe.
Same as other earlier Hot Toys release, the head sculpt of Tony Stark is off while the prototype was better.
There are the flame thrower and the missile launcher on each arm as weaponry. Because of all the intricate details on the figure, the articulation is almost none. It can only stand up straight with a little bit of arm movement. (Cannot lift-up too far though)
But sacrificing the articulation and play-ability to trade off for incredible details, it's still worthy. Cause the figure just looks awesome! It's a state of the art!!
