Character Background
Based on the primary form of the AI antagonist Ultron from the 2015 film Avengers: Age of Ultron, created by Tony Stark and Bruce Banner.
Design Notes
The use of the unique neck-mounted chin piece was a creative solution to capture Ultron's non-humanoid head shape without requiring a completely new head mold.
Similar Minifigures
Ultimate Ultron (sh176), Ultron MK1 (sh169), and various Sentry droids (sh166).
Collectibility
High demand for completions of the Avengers villain roster; stable value as it is the most 'iconic' version of the film character.
History
Part of the first major wave of MCU figures that utilized specialized 'Pearl' plastic colors to simulate metal rather than standard light gray.
Interesting Facts
Despite being the titular villain, this specific 'Prime' version only appeared in one set, while his minions appeared in several.
Display Suggestions
Display alongside the 2015 Hulkbuster or in a 'creation' scene with a damaged Iron Man MK43. Use blue LED lighting to contrast the red accents.
Modification Potential
The head bracket piece is a favorite for MOC builders creating custom droids or cybernetic characters. Compatible with most standard neck-attachment gear.
Overall Assessment
An excellent mid-2010s licensed figure with top-tier printing and a clever piece usage for the head. A staple for any Marvel LEGO collector.
