Year Released

2016 - Released in the Iron Skull Sub Attack (76048) during a wave focused on specialized Marvel armor sets.

Rarity

Uncommon to Rare. While not a limited convention exclusive, it appeared in only one mid-priced set that is now retired. Its unique sand-green color makes it highly sought after for Hall of Armor collectors.

Head

Standard Tony Stark light flesh head with dual-sided printing (neutral and concentrated/HUD expressions) under a Sand Green helmet with a Pearl Gold flip-up faceplate.

Torso

Sand Green torso with detailed mechanical plate printing, featured gold and dark orange accents, and a circular Unibeam/Arc Reactor in the center. Includes back printing matching the deep-sea suit aesthetic.

Legs

Sand Green legs with elaborate printing on the front of the hips and legs, depicting heavy reinforced armor plating and boot stabilizers suited for high-pressure deep-sea environments.

Accessories

Usually comes with trans-light blue Power Blast pieces or circular studs representing repulsor blasts (not pictured in the main focus of the image). The helmet and faceplate are the primary structural accessories.

Color Scheme

Primary Sand Green with Pearl Gold faceplate and accents. This is the only Iron Man suit to utilize Sand Green as the primary color, mimicking the 'deep-sea' MK 37 specialty.

Printing Details

High-density pad printing on the torso (front/back) and legs. The line work is fine, featuring dark grey mechanical outlines and metallic copper/gold highlights to create depth.

Variants

This is the only version of the Mark 37 'Hammerhead' armor produced by LEGO. It differs significantly from standard red/gold Iron Man variants.

Condition Notes

The Pearl Gold faceplate is prone to surface scratches. Check the 'neck' of the torso for hairline cracks, a common issue with the 2016-era plastic mold.

Estimated Value

Used: $15 - $25; New/Pristine: $30 - $40. Value is heavily driven by 'Hall of Armor' completist collectors.

Price (New)

Originally included in set 76048 which retailed for $29.99 USD in 2016.

Compatible Sets

76048 Iron Skull Sub Attack (2016).

Character Background

The Mark 37, codenamed 'Hammerhead,' is a Deep Sea Suit designed by Tony Stark to withstand extreme pressure and low temperatures, appearing in the 'Iron Man 3' House Party Protocol.

Design Notes

Utilizes the classic flip-up helmet mold. The choice of Sand Green was a creative and accurate way to represent the suit's specialized coating seen in movie concept art.

Similar Minifigures

Iron Man Mark 39 'Starboost' (sh214), Iron Man Mark 33 'Silver Centurion' (sh232), and Iron Man Mark 1 (sh565).

Collectibility

High. Because it is a unique armor designation (MK 37), it is a staple for MCU minifigure collectors and the secondary market price remains stable.

History

Part of a 2016 movement where LEGO expanded beyond the 'main' suits to include specialized armors from the Iron Man 3 movie climax.

Interesting Facts

The 'Hammerhead' suit in the comics and film concept art is often more of a teal/blue color; LEGO’s use of Sand Green is considered one of the most aesthetically pleasing 'non-red' Iron Man figures.

Display Suggestions

Best displayed in a 'Hall of Armor' MOC or alongside the Iron Skull/Submarine elements from its original set. Looks striking next to the white Mark 39 suit.

Modification Potential

Excellent for custom deep-sea divers or sci-fi soldiers due to the rare sand green armor printing.

Overall Assessment

A top-tier Iron Man variant. The unique color palette and high print detail make it a standout figure that has aged very well since its 2016 release.
