The Fire Knight Mech presents a solid investment opportunity, fueled by the enduring popularity of the Ninjago theme and the inherent appeal of mechs to LEGO collectors. Its substantial piece count and the inclusion of an exclusive Kai minifigure enhance its long-term value. While the current price trend is falling, this could represent an attractive entry point for investors who believe in the set's potential for appreciation, especially as it nears retirement. Historically, Ninjago sets with unique minifigures and distinctive designs have performed well on the secondary market, suggesting a positive outlook for this set.

Ninja Ultra Combo Mech

The Fire Knight Mech offers a unique building experience compared to other Ninjago sets, focusing on mech construction rather than vehicles or buildings. While sets like the Ninjago City Gardens (71741-1) offer more complex building techniques and display options, the Fire Knight Mech provides a more straightforward and poseable model. Collectors interested in mechs might also consider LEGO Marvel's Iron Man figures, but the Ninjago set offers a distinct aesthetic and play style.

2 Minifigures Included

The set includes a Kai minifigure, the Master of Fire, and a Fisherman. The Kai minifigure is exclusive to this set, making it highly desirable for collectors.
