Head

Yellow head with Kai's signature determined expression, distinct scarred eyebrow, and red mask with a gold techno-symbol (Techno Blade icon) on the forehead.

Red torso with stone armor printing: featuring a brown strap with pouches, a dark red sash, and intricate mechanical or techno-detailing on the back.

Legs

Red legs with dark red and brown printing, depicting a continuation of the sash and light armor padding on the knees.

Accessories

Flat Silver Katana held in a Dark Blueish Gray scabbard/neck bracket piece. Originally came with a red Techno Blade in some sets.

Color Scheme

Bright red primary with dark red, brown, and metallic gold accents, reflecting the character's fire element and the season's technological theme.

Printing Details

High-quality pad printing on the torso front and back, the front of the legs, and a detailed metallic gold icon on the mask.

Variants

This 'Stone Armor' version is distinct from the standard Rebooted Kai (njo087), which lacks the heavy strap printing and has a different mask pattern.

Condition Notes

Prone to silver paint wear on the katana and friction looseness in the neck bracket. Check for micro-cracks on the red torso under the arms.

Estimated Value

Used: $4 - $7 USD; New: $10 - $15 USD. Value varies slightly based on whether the original Techno Blade accessory is included.

Available in sets ranging from $14.99 (Kai's Fire Mech) to $69.99 (Ninjago City Chase).

Compatible Sets

70721 Kai Fighter, 70727 Ninja Charger, 850932 Ninjago Accessory Set, and 70720 Hover Hunter.

Character Background

Kai is the Elemental Master of Fire. In the Rebooted season, he and the Ninja transition from traditional warriors to high-tech defenders against the Digital Overlord.

Design Notes

Notable for being one of the first Ninjago designs to blend feudal aesthetic with industrial/digital details like the pouches and techno-symbol.

Similar Minifigures

Lloyd - Rebooted (njo095), Jay - Rebooted (njo090), and Cole - Rebooted (njo092).

Collectibility

High for Ninjago completionists as it represents a core look from one of the most popular story arcs of the series.

History

Follows the 2011-2012 ZX and Kimono versions; this suit marked a shift toward more 'utilitarian' ninja gear during the 2014 brand revival.

Interesting Facts

The symbol on the head is the LEGO Ninjago 'Techno' cipher, which fans have translated to represent specific elemental powers.

Display Suggestions

Best displayed alongside other Rebooted ninja or inside the 70721 Kai Fighter cockpit for a dynamic look.

Modification Potential

The red stone-armor torso is extremely popular for MOCs (My Own Creations) involving custom medieval knights or post-apocalyptic warriors.

Overall Assessment

A quintessential 2014 Kai figure. While not the most expensive, its design clarity and thematic continuity make it a solid piece of LEGO Ninjago history.
