Forecast Model

This shows the set's value since release and where our forecast expects it to go.
LEGO 76307 Iron Man Mech vs. Ultron is a Marvel Super Heroes Avengers set released in 2025, containing 101 pieces and 2 minifigures. The build centers on a poseable Iron Man mech with movable arms, legs, and fingers, and a torso that opens to reveal a minifigure cockpit. Weaponry includes a dual stud shooter mounted on the mech’s right arm. The set includes an Iron Man minifigure with a flip-open helmet and reversible head, and an Ultron minifigure equipped with a laser beam element.

Once it retires, which we expect in 2026, our forecast sees a pop of about 10% and a value near $21 within five years.
Retirement risk. Iron Man Mech vs. Ultron is expected to retire soon, by the end of 2026.
Collector and Investor Standing
Ultron and Iron Man give this mech its collector pull: Ultron appears in no other set, and Iron Man wears dark red and gold armor with pearl gold arms. The opening cockpit and movable fingers give the figures a proper place to clash. Investor interest also rests on broad member interest and Marvel's record of holding value.

“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.”
Full review at www.brickfanatics.com
BrickEconomy Member Review
“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.”
 
Excerpts from third-party reviews

About Marvel Super Heroes Avengers

Avengers gathers the LEGO Marvel sets built around the team rather than a single hero. It opened in 2012, timed to the first Avengers film, with the heroes facing Loki and his Chitauri invaders, and it has since borrowed from the comics too, setting Iron Man against Detroit Steel and Hulk against Red Hulk in 2017.

Avengers was introduced in 2012 and currently consists of 43 sets. As of today, 76166 Avengers Tower Battle is the most valuable Avengers set with an estimated new/sealed value of $248.
