njo0037 - LEGO Minifigure Value & Collector Guide
Kai ZX - Ninja Rocket Pack
Kai has 84 LEGO variants spanning 2011–2026. NJO0037, released in 2012, is the 5th of those variants.
At £7.17, NJO0037 is one of the more valuable Kai variants. The highest-valued variant — NJO0186 - Kai - Rebooted, Stone Armor — currently trades at £97.78.
NJO0037 ranks in the top 50% of all minifigures tracked on Brickpit by used value, and in the top 25% within the NINJAGO theme (989 figures).
NJO0037 sits in the mid-range of Kai variants by value. With all source sets now retired, supply is not growing — a factor that typically supports price stability over time.
Price History
Set Appearances
NJO0037 was produced exclusively for Rattlecopter (9443), a smaller, entry-level set originally retailing at £24.99. The set retired in 2012, so NJO0037 is now only available secondhand.
All Kai Variants
There are 83 other minifigure variants of Kai.
