Kai (Possession)

The Kai (Possession) minifigure is desirable for Ninjago collectors due to its unique design reflecting a specific storyline. The scar across Kai's left eye and the detailed print on the torso and legs, indicating his possessed state, make it stand out from other Kai minifigures. The inclusion of the neckwear/shoulder pads with katana scabbards adds to the overall appeal.

As this minifigure is from a retired set, its availability is limited, further increasing its collectibility. Condition is vital; a minifigure in excellent condition with all accessories will command a higher price.

This Kai (Possession) minifigure appears in only one set: Ninjago: The Djinn Menace (9781405283236-1) released in 2018. Given that the set is now retired, the minifigure's availability is limited to the aftermarket. While not a regional exclusive, the single set appearance contributes to its relative rarity compared to Kai minifigures that appear in multiple sets across different years.

The Kai (Possession) minifigure has moderate investment potential. As a character from the popular Ninjago theme, it benefits from a dedicated fanbase. The fact that it's from a retired set enhances its desirability. While not the rarest or most expensive Ninjago minifigure, its unique design and limited availability suggest a potential for value appreciation over time, especially if the Ninjago theme continues to maintain its popularity.
