“An Iron Man mech might sound novel and interesting on paper, but only if that paper was written five years ago. 76307 Iron Man Mech vs. Ultron is Tony Stark’s third supersized mechanical suit of armor (as opposed to his regular mechanical suit of armor) in as many years, but... More this one at least bundles in a returning baddie from the Infinity Saga who doesn’t come around all that often.”

“This set delivers a solid mix of playability and collectible minifigures. The Iron Man mech features a sleek design with articulated joints, a stud shooter, and a functional cockpit for the included Iron Man figure. The standout is the Ultron minifigure, showcasing detailed printing and a striking new helmet attachment. While the mech’s design isn’t groundbreaking, the inclusion of two high-quality figures makes it a great value.”
