Figure ID
njo091
Theme
Ninjago
Year Released
2014. It debuted during the height of Ninjago's 'Rebooted' wave, which marked the theme's transition from a fantasy setting to a more techno-futuristic landscape.
Rarity
Uncommon. While not a limited convention exclusive, this specific 'Stone Armor' variant appeared in fewer sets than his standard techno-robe counterpart.
Head
Yellow classic skin tone with angry determined eyes and eyebrows. Features a red wrap-around mask (ninja scarf) and a black 'Rebooted' style hairpiece/wrap combination.
Torso
Black torso with red sleeves and black hands. Features detailed printing of a red/gold dragon emblem on the left chest, golden robe clasps, and a red sash belt that continues to the back.
Legs
Black legs with red and gold printing. Design includes knee armor detailing, matching the golden accents and rope ties seen on the torso's sash.
Accessories
Equipped with two Pearl Gold katanas and a gold scabbard (back-mounted shoulder armor with dual sword slots). Some sets included a Techno-Blade, but the primary identifiers are the gold swords.
Color Scheme
A striking palette of Black and Red (Kai's primary color) with extensive Pearl Gold accents representing the 'Stone Armor' upgrade.
Printing Details
High-quality pad printing on the front and back of the torso, as well as the front of the legs. The gold is vibrant and the line work is sharp, typical of 2014 NINJAGO standards.
Variants
Variants of Kai from this era include the standard Techno-Robe (njo083) and the Kimono outfit. This specific Stone Armor version is distinguished by its darker black base color.
Condition Notes
Prone to silvering or scratching on the black torso and legs. Check for 'neck cracks' on the torso and loose arm joints. Gold printing on the chest can rub off with heavy play.
Estimated Value
Used: $5 - $9; New (pulled from set): $12 - $18. Value remains steady due to Kai's popularity, though mass production prevents high-end rarity.
Price (New)
Available in sets ranging from the $19.99 Kai's Fire Mech to larger $70+ battle sets. It was not sold as an individual CMF.
Compatible Sets
Appears in 70721 Kai Fighter and 70727 X-1 Ninja Charger, as well as the 850932 Ninjago Accessory Set.
Character Background
Kai is the Elemental Master of Fire. In the Rebooted storyline, the ninjas receive 'Stone Armor' to protect themselves against the Digital Overlord's corruption and Nindroid armies.
Design Notes
A significant departure from earlier 'Zukin' style garbs, focusing on a more rugged, tactical aesthetic. The use of black as a primary color for Kai was a notable design shift for this season.
Similar Minifigures
Stone Armor versions of Cole (njo092), Jay (njo093), and Lloyd (njo095) share the same sub-theme design language.
Collectibility
Moderate. It is essential for fans of the 'Rebooted' era of Ninjago. While common, its high aesthetic appeal makes it a favorite for display-focused collectors.
History
Follows the 'Legacy' of the first two seasons; this was part of the wave that proved Ninjago could survive beyond its originally intended Series Finale at the end of the 2012 'Deepstone' arc.
Interesting Facts
The 'Stone Armor' was literally made from the remains of the indestructible Stone Army, meant to be impervious to the Overlord's laser-based weaponry.
Display Suggestions
Best displayed alongside other Ninjas in their Rebooted gear. Using a 'trans-blue' tech-themed baseplate enhances the futuristic Season 3 vibe.
Modification Potential
The black and red torso is excellent for custom 'Ronin' or dark-themed samurai MOCs. The gold scabbard remains one of the most useful armor pieces for ninja customs.
Overall Assessment
A solid, classic NINJAGO figure. It represents one of the most creative design periods in the theme's history where traditional ninja elements met sci-fi aesthetics. 8/10 for design.
