Unpopular opinion: Age of Ultron is one of the better MCU movies and Ultron was a great villain. Just COMPLETELY different from the comics but we haven't been used to it yet by then. Not like movie Thanos was anything like the comic version anyway.

Here's a comic inspired Ultron figure with the head stolen from his in game MvC Infinite model. Plus 2 drones because one is a lonely number. He is based on a DST Pacific Rim 2 figure whose name escapes me yet again. The robot was about 8.5" tall but I was fortunately able to shorten around an inch or so. Took me a couple years to finally commit to doing that. I'm really happy with the final effect, not gonna lie.

Recipe:
head - 3D print based on MvC Infinite
body - DST Pacific Rim 2 Obsidian something
drones - McF JL Cyborg
