The Brothers Brick
“The Ninjago Legacy theme revisits classic Ninjago sets with updated builds and designs. Turning back the clock to Season 3, the 71704 Ninjago Legacy: Kai Fighter reprises 2014’s 70721 Kai Fighter, more than doubling that set’s 196 pieces to a much heftier 513 part count.”

“As part of this year’s Legacy subtheme, 71704 Kai Fighter is the second version of the fire ninja’s jet, following 2014’s set of the same name. However, it’s a significant upgrade on the design with more than double the pieces than before, as well as double the ninjas and... More double the enemies. Four minifigures are included with the set. Our heroes are Kai and Lloyd, two of the most common Ninjago characters. Neither are wearing any headgear, save for a mask; instead, opting for their signature hair.”

About Ninjago Legacy

The Ninjago Legacy subtheme of Ninjago is dedicated to re-imagining concepts used in classic sets. The first wave consisted of re-imagined sets from Seasons 1 and 2 and released in early 2019. The second wave, released in 2020, consisted of sets from the pilot episodes and Seasons 2–4. So far there have been 5 waves, the third wave consisted of sets from Seasons 1 and 3. The fourth wave focused on sets from seasons 2–5 and the fifth wave consisted of sets from the pilot episodes and seasons 1 and 5. Rather than conform to a specific season, Legacy is based on the Ninjago franchise's early history, with the first wave celebrating the television show's tenth season and 100th episode.

Legacy was introduced in 2019 and currently consists of 37 sets. As of today, 71741 NINJAGO City Gardens is the most valuable Legacy set with an estimated new/factory sealed value of $401.

Ninjago Legacy Kai Fighter set 71704 was released in June 2020, retailing for $40, but has since been retired. New, unopened Kai Fighter sets are valued at $90, while used sets can be found for $25 in good condition.
