In the Battle for Azeroth expansion there is a Kingdom Hearts reference. Specifically, if the player goes to the Thresher's Wharf area of Stormsong valley and climb a tall structure they can find three Beleaguered Watchmen looking out dramatically at the water. The way they are positioned, dressed, and how the scene is choreographed, make them look like the three original human characters from Kingdom Hearts: Sora, Kairi, and Riku.
