Year Released
2015 - Released during the peak of the Marvel Cinematic Universe hype, coinciding with the 'Avengers: Age of Ultron' theatrical release.
Rarity
Common to Uncommon - This figure was mass-produced across several sets of various price points in 2015, including a battle pack, making it easily accessible for army building.
Head
Pearl Dark Gray with light blue 'glow' printing for the mouth and eyes under a heavy eyebrow ridge; it uses a unique molded head piece rather than a traditional minifigure head to better replicate the robotic aesthetic.
Torso
Pearl Dark Gray with intricate mechanical printing in silver, black, and light blue accents. Features a 'U' shape motif on the chest. Print quality is high, though restricted to the front and back of the torso (no arm printing).
Legs
Pearl Dark Gray with printed silver and black mechanical armor plating details on the front. Matching the torso's aesthetic of a complex robotic shell.
Accessories
Equipped with a brick-built stud shooter weapon consisting of a Light Bluish Gray trigger base and a Transparent Light Blue 1x1 round plate 'stud' meant to be launched via a spring-loaded mechanism.
Color Scheme
Primary color is Pearl Dark Gray (Metallic), with Metallic Silver highlights, Black contouring, and Transparent/Light Blue glowing accents representating energy.
Printing Details
Highly detailed pad printing on the head, torso front, torso back, and leg front. The silver metallic ink provides a realistic sheen that differentiates it from standard gray plastic.
Variants
There are several variants including the Ultron Sentry Officer (sh167) which features a different head/neck piece and the Ultron Prime/Ultimate versions which have significantly different molds and colors.
Condition Notes
The metallic Pearl Dark Gray plastic can show 'scuffing' or 'marbling' more easily than solid flat colors. Common wear points include the stud-shooter trigger becoming loose and silver printing on the legs rubbing off with heavy play.
Estimated Value
New: $4.00 - $6.00 | Used: $2.50 - $4.00. Value remains low because they were intended to be collected in multiples for 'army building'.
Price (New)
Available in sets ranging from $12.99 (76029 Iron Man vs. Ultron) to $74.99 (76032 The Avengers Quinjet City Chase).
Compatible Sets
76029 Iron Man vs. Ultron, 76031 The Hulkbuster Smash, 76032 The Avengers Quinjet City Chase.
Character Background
Autonomous robotic drones created by Ultron to serve as his infinite army. They share a collective hive mind and were used to attempt the extinction of humanity in the fictional city of Sokovia.
Design Notes
The use of the specialized 'Ultron' head mold was a significant departure from the standard blocky minifigure head, allowing for a more accurate cinematic silhouette.
Similar Minifigures
Ultron Prime (sh175), Ultron Ultimate (sh176), and Marvel's Outriders or Chitauri soldiers which also serve as army-builder 'grunt' characters.
Collectibility
Moderate. High demand for army builders who want screens of robots for dioramas, but low individual value due to high supply.
History
Marked the transition where LEGO began creating more specialized molds for licensed characters rather than relying on standard headgear/hair pieces.
Interesting Facts
The stud shooter accessory held by the figure was introduced shortly before this wave as a play feature to replace older non-firing blaster molds.
Display Suggestions
Best displayed in a phalanx or 'horde' formation behind a version of Ultron Prime. UV-protected cases are recommended to keep the metallic pearl finish from dulling.
Modification Potential
Excellent for sci-fi MOCs. The torso and legs are often repurposed by customizers to create 'Gray Fox' from Metal Gear or other high-tech cyborgs.
Overall Assessment
A solid, highly detailed 'grunt' figure that captures the MCU look perfectly. It is an essential piece for Marvel collectors, specifically for those looking to recreate the Battle of Sokovia.
