Figure ID

Theme

Hidden Side

Year Released

2019 - Released as part of the debut wave for LEGO Hidden Side, an AR-integrated theme.

Rarity

Uncommon. While not a limited edition, it was exclusive to one specific set (70421) and the Hidden Side theme was discontinued after a short run.

Head

Trans-Yellow head with standard face print featuring white pupilless eyes, a jagged 'monster' mouth, and dark orange/brown facial details.

Torso

Bright Yellow torso with a collared shirt print, featuring pockets and tattered, burned edges. Includes dark orange flame/damage highlights. Solid yellow arms and hands.

Legs

Trans-Yellow Ghost Lower Body (Tornado/Swirl style) with internal marbled yellow/clear dual-injected plastic.

Accessories

None included in the image; however, in-set it was often paired with a chain or translucent weapon elements.

Color Scheme

Monochromatic bright yellow and trans-yellow palette with dark orange and white printing accents to simulate a fire-based specter.

Printing Details

High-quality pad printing on the head and torso. The torso features front-only printing of a tattered button-down shirt with detailed burn holes.

Variants

There are several 'Ghost' variants in Hidden Side using the same leg mold, but this specific 'Fire' version with the yellow shirt and trans-yellow head is unique to its set.

Condition Notes

The trans-yellow plastic is prone to minor surface scratches. Check for cracks in the torso side-seams, a common issue for 2019-era yellow plastic.

Estimated Value

Used: $3.00 - $5.00 USD; New (assembled from set): $6.00 - $8.00 USD. Value is stable but low due to high set volume.

Price (New)

Included in El Fuego's Stunt Truck (70421) which retailed for $39.99 USD.

Compatible Sets

70421 El Fuego's Stunt Truck.

Character Background

In Hidden Side lore, this is a 'haunted' citizen of Newbury. These ghosts appear when the town is possessed by the Hidden Side, led by the villain Lady E.

Design Notes

Features the 'Ghost Cloud' lower half, a specialized mold introduced to depict ghosts without legs, allowing them to 'hover' on studs.

Similar Minifigures

hs009 (Ghost/Specter Blue), hs011 (Ghost/Specter Pink), hs043 (Ghost/Specter Green).

Collectibility

Moderate. Collectors of 'scary' or 'supernatural' LEGO figures value these for their unique translucent parts and specialized leg molds.

History

Represents LEGO's first major attempt to blend physical play with a digital Augmented Reality app.

Interesting Facts

The shirt printing is a 'corrupted' version of common LEGO City townsperson attire, intended to show the citizen was possessed while in their work clothes.

Display Suggestions

Best displayed on a black baseplate or inside light-up cases to let the Trans-Yellow plastic glow.

Modification Potential

The trans-yellow tornado piece is highly sought after for MOCs involving fire spirits, elementals, or customized Super Heroes (like a custom Human Torch).

Overall Assessment

A solid, visually striking figure with great part-use in the lower half. Highly recommended for fans of the supernatural or those seeking unique translucent elements.
