Master Wu Key Chain

The Master Wu Key Chain, released under set number 5004915-1, was introduced by the LEGO Group as a promotional accessory tied to the release of The LEGO Ninjago Movie in 2017. It features a molded plastic minifigure of the character Master Wu, the wise mentor and leader of the ninja team, permanently attached to a sturdy metal ring and chain. This item was primarily distributed through official LEGO brand stores and during specific marketing events surrounding the film's theatrical debut, serving as a functional collectible for fans of the long-running Ninjago franchise.

The design of this keychain captures the distinct aesthetic of the movie-version minifigure, retaining the character's traditional straw hat and flowing beard while adapting the form for daily utility. Created by the LEGO design team to appeal to both younger fans and adult collectors, the piece adheres to the company's commitment to durability and character-accurate detailing. Because it was produced as a mass-market promotional gift rather than a standard building set, it is regarded as a quintessential piece of Ninjago memorabilia, marking a specific era in the property's cinematic transition.
