Upon hearing the rumor that Ultron will go through three 'upgrades' during the movie (initial build, advanced build, vibranium alloy build) I decided on making his advanced 'Mark II' themed body. This custom Marvel Legends Ultron was created using the Mark 32 Iron Man body, arms and legs from an old ML Ultron, head from the Iron Monger BAF Ultron, and various halo Elite armor sections. New curved movie-style antenna-ears were attached and his whole armored body detailed up with panel lining and weathering. We can't forget the trademark Kirby bubbles in his mouth and once those were added Ultron was ready to wreak havoc!
