Theme
Ninjago
Year Released
2022 - Released during the Ninjago Core wave, which was designed to provide iconic versions of characters independent of the TV show's 'Seabound' or 'Crystalized' storylines.
Rarity
Common; this figure was distributed in multiple affordable sets and the Wave 1 EVO series, making it highly accessible to mass-market consumers.
Head
Yellow head with determined/angry expression, featuring Kai's iconic scar over his left eye. Topped with a red two-part ninja wrap (mask upper and chin piece).
Torso
Black torso with red sleeves and black hands. Printing features a red/gold dragon emblem on the right chest, gold robe fasteners, and a red belt sash. Back printing continues the robe and belt detail.
Legs
Black legs with red hip joint. Features printed red sash ends hanging from the belt, red knotted rope details on the shins, and knee padding outlines.
Accessories
Equipped with a Pearl Gold katana. Typically includes a 'scabbard' neck piece (not fully visible but implied by the blade position) which holds the sword on the back.
Color Scheme
Primary Red and Black with Pearl Gold accents. This reflects Kai's Elemental Master of Fire status while utilizing the Core line's high-contrast aesthetic.
Printing Details
High-quality pad printing on torso (front/back) and legs (front). Features the distinct 'Core' dragon motif which is sharper and more stylized than earlier Legacy versions.
Variants
Similar to njo551 (Legacy Kai) but distinguished by the specific dragon print logo and the lack of arm printing found in more expensive 'Master' versions.
Condition Notes
Prone to 'neck crack' stress marks if the scabbard piece is removed frequently. Gold printing on the chest can rub off with heavy play. Check torso-to-hip friction for 'loose' joints.
Estimated Value
Used: $2.00 - $4.00; New/Pristine: $5.00 - $7.00. This is an entry-level collector piece due to high circulation.
Price (New)
Available in sets ranging from $9.99 (Kai's Fire Dragon EVO) to $39.99 (Ninja Ultra Combo Mech), making the individual figure value very low relative to MSRP.
Compatible Sets
71762 Kai's Fire Dragon EVO, 71765 Ninja Ultra Combo Mech, 71767 Ninja Dojo Temple, and 112220 (Ninjago Magazine Gift).
Character Background
Kai is the Elemental Master of Fire and the hot-headed older brother of Nya. Originally a blacksmith, he was the first recruit of Master Wu and remains a core member of the ninja team.
Design Notes
The 'Core' design was a reset for LEGO to move away from show-specific outfits, focusing on the character's 'essence'—hence the simple but iconographically dense dragon motif.
Similar Minifigures
njo551 (Legacy Kai), njo636 (Epic Battle Kai), njo705 (Seabound Kai).
Collectibility
Low to Moderate; essential for a complete Kai collection, but not a primary investment piece due to its inclusion in four different products.
History
Represents the 11th year of Ninjago. This specific design moved away from the complex Japanese kanji seen in 'The LEGO Ninjago Movie' toward a more classic comic-book style.
Interesting Facts
The dragon print on the chest is designed to look like the number '1' or a stylized 'S', though it is officially just a flame-dragon hybrid logo.
Display Suggestions
Displays well alongside the other 2022 Core Ninja (Lloyd, Zane, Jay, Cole) to show the unified 'Core' team aesthetic. Use a 'Power Up' transparent flame piece for effect.
Modification Potential
Excellent for 'purist' customs; the black torso with red sleeves is a versatile base for other martial arts MOCs or custom fire-themed heroes.
Overall Assessment
A solid, well-designed figure that serves as a perfect introduction to the character. While not rare, it captures the 'Fire Ninja' identity perfectly with high-quality printing.
