Fortnite's ongoing Chapter 7 Season 4 will feature a crossover with the Kingdom Hearts series, introducing Sora, Riku, and Kairi as playable skins. The trailer showcases the trio in their Kingdom Hearts 2 designs, wielding their iconic Keyblades and engaging Heartless-like enemies in an environment reminiscent of Destiny Islands. The musical backdrop for the trailer is Utada Hikaru's "Sanctuary," the theme song from Kingdom Hearts 2.

While the trailer does not depict the characters using firearms, the announcement implies they will wield weapons in Fortnite. This marks a significant shift for Kairi, a character often relegated to a supporting or damsel-in-distress role within her own series. Despite her growing importance as a Guardian of Light in Kingdom Hearts 3 and her playable roles in the Re Mind DLC and the Melody of Memory rhythm game, fans have expressed dissatisfaction with her narrative treatment. The Fortnite collaboration offers players the opportunity to embody Kairi in a more active, combat-oriented capacity.

The next major Fortnite update is scheduled for Thursday, September 17, and is expected to include the release of Sora, Riku, Kairi, and Roxas skins. It is also anticipated that Sora's Keyblade will be available as a weapon within the game's loot pool.
