Ah-May-Zinkkk!!!
That's what in my mind when I first get my hand on this beast! (Not really a beast though). The final suit to be appeared in the latest Avengers Age Of Ultron movie, the Mark 45 simply put Iron Man suit on another level (for film) which (some say) inspired by Iron Man iconic suit in the comic, the Bleeding Edge Armor (which also rumored will be appeared on Captain America: Civil War).
