Designer's notes[]
"I made all of the Ninjago magazine builds for 2017! We chose these figures to give kids another way to get the classic Ninja costumes, but I also wanted to include a fun weapon build that was reminiscent of their original Golden Weapons. Kai has a Fire chainsword, mostly because Gold chainsaw pieces are great."[1]
Trivia[]
- In this set, Kai comes with an incorrect double-pauldron golden armor and not his single-pauldron dark brown Honor robe armor.
