Kingdom Hearts Missing-Link’s Leaked Cinematic May Have Clues For KH4 - Kotaku

What the report says

Kotaku reported that a cinematic believed to be the opening sequence for the canceled mobile game Kingdom Hearts: Missing-Link circulated online over the weekend, prompting fans to examine it for possible connections to Kingdom Hearts IV. Kenneth Shepard wrote on July 20, 2026, that Missing-Link was not expected to release, but Square Enix had previously framed it as part of the broader Kingdom Hearts storyline, with some of its characters apparently tied to the next mainline entry.

According to Kotaku, the footage appears to show a team of Keyblade wielders in astronaut- or deep-sea-diver-like suits battling a large Heartless in a dark, isolated space. Fans have interpreted the suits as a possible new version of Keyblade Armor, previously used for travel through dangerous routes between worlds. The article notes that Missing-Link was meant to involve early expeditions into the Astral Plane from Scala ad Caelum, making that setting a possible explanation for the scene.

Kotaku also highlighted visual details that fans are linking to earlier games and to Kingdom Hearts IV. The cinematic reportedly includes imagery reminiscent of characters falling through water into the “Dive to the Heart,” while the world of Quadratum — a realistic Tokyo-like setting central to Kingdom Hearts IV marketing — appears after the Heartless fight. These observations have fueled speculation about Sora’s relationship to Quadratum, though the article presents that as fan theory rather than confirmed plot information.

The most concrete potential link involves characters: Kotaku says the footage appears to show Brain from Kingdom Hearts Union X and Sigurd, whose face seems to match a new figure seen in Kingdom Hearts IV trailers. If accurate, the canceled game’s story may still matter for understanding the next installment.
