Kingdom Hearts 4 Guide: Everything We Know

Since its 2022 unveiling, Kingdom Hearts IV has remained a tantalizing mystery. Square Enix has released two trailers, a handful of screenshots, and scattered tidbits, but the fan community has been left to sift through the crumbs. What concrete information can we extract from the studio’s official communications, beyond the endless speculation?

Untangling the plot of the forthcoming title is no small task. The game appears to pivot away from the series’ Disney‑centric roots, delving instead into its own original mythology. Sora finds himself in Quadratum—a city modeled after real‑world Shibuya—that first surfaced as the setting of an in‑universe game called Verum Rex within the Toy Story universe. Now, Kingdom Hearts expands its intricate multiverse, treating Quadratum as a fictional yet “real” realm. After the events of Kingdom Hearts III and its Re:Mind DLC, Sora is transported to this new world, while his companions Riku and Kairi uncover his location through the rhythm‑based game Melody of Memory. Riku ventures into Quadratum in search of Sora, and Kairi remains to brief the Disney crew on their findings.

That’s the barebones premise, but anyone familiar with the series knows the truth is far more intricate. Over the past 24 years, Kingdom Hearts has spun an elaborate narrative that makes every entry a prerequisite for full comprehension. Players who have only tackled the numbered titles will find themselves adrift in a sprawling tapestry of lore.

From the two trailers and the screenshots released so far, it’s clear that a host of Kingdom Hearts characters will make appearances in KH IV, though their exact roles remain uncertain. Sora returns as the primary protagonist, yet he won’t be the sole playable hero. A screenshot suggests that Mickey Mouse will be playable in certain sequences, while Donald and Goofy are briefly shown in the trailers—though we haven’t yet seen them battle alongside Sora. Additionally, Hades’ voice actor, James Woods, hinted that he’s recorded for the game, indicating the infamous villain could return after featuring in every mainline entry to date.

While the familiar Disney trio and Hades remain central, the rest of Kingdom Hearts IV’s ensemble is largely composed of original series characters, many of whom will only resonate with fans who followed the now‑defunct mobile titles. Luxord, the card‑wielding Organization XIII veteran, will join the Quadratum roster, alongside mobile‑game figures Strelitzia, Valdi, and Sigurd. The shadowy Master of Masters and his protégé Luxu are also slated to appear. In a surprising twist, Xehanort will return—but in a younger incarnation, rather than the aged adversary we confronted in Kingdom Hearts III. No word yet on whether any Final Fantasy icons will make an appearance; the series largely omitted them until the Re:Mind DLC, so their inclusion remains uncertain.

Riku, the series’ deuteragonist, has yet to surface in any promotional material for Kingdom Hearts IV, but his journey to Quadratum at the end of Melody of Memory suggests he will likely make an appearance, adding further depth to the story’s emotional stakes.

Kingdom Hearts IV is poised to resemble a mainline Final Fantasy title more closely than any previous entry. Historically, the franchise has blended Sora into Disney worlds with an anime‑inspired aesthetic, avoiding jarring transitions. After Kingdom Hearts III’s toy‑like visual approach, Square Enix has opted for a photorealistic style, a decision rooted in Sora’s presence in Quadratum. While earlier games adapted Sora’s look to fit each Disney setting, this marks the most radical visual transformation the series has ever undertaken.

“From Sora’s perspective, Quadratum is an underworld, a fictional realm that differs from reality,” director Tetsuya Nomura explained in 2022. “However, for the inhabitants of Quadratum, their world is real, and the realm where Sora and his companions exist is the other side, a fictional domain.”

So far, the only glimpse we’ve received of Kingdom Hearts IV comes from the Quadratum footage, leaving fans wondering whether Disney’s iconic realms will finally make an appearance. The hint that Hades could return—whether with Sora or another hero—suggests a possible excursion to Olympus, though that remains unconfirmed. A single screenshot of Mickey Square shows the King navigating Scala ad Caelum, the legendary nexus of the series’ worlds, a logical destination given Mickey’s exile there by Yensid at the end of Melody of Memory. Yet, if you’re hoping for a visit to Moana’s island or the dynamic duo of Nick and Judy from Zootopia, there’s still no word on those possibilities.

Despite the limited footage, one frame in the original trailer has sparked speculation that a Star Wars‑inspired sequence might be on the cards. It’s only natural to anticipate that the franchise could eventually incorporate Star Wars or Marvel elements, given the powerful brand synergy and the series’ history of blending diverse universes.

Official confirmation now confirms that the forest moon of Endor will indeed serve as a playable world in Kingdom Hearts IV, a development that expands the game’s mythos and taps into the enduring allure of the Star Wars saga.

Whether the canceled mobile title Missing‑Link, slated to precede Kingdom Hearts IV, will be woven into the new game remains uncertain. A leaked cinematic suggests that characters originally intended for the mobile title—such as Sigurd—might appear in the upcoming release. Given that Kingdom Hearts titles often serve as pivotal pieces of the series’ overarching puzzle, it’s plausible that Square Enix had planned to introduce significant story elements through Missing‑Link before its cancellation. We’ll have to wait and see how—or if—the studio integrates those characters and plot threads into the forthcoming installment.

Kingdom Hearts IV’s combat, as revealed in recent footage, feels true to the franchise’s legacy—swift, energetic, and brimming with the trademark keyblade flair. Sora deftly slices through Heartless, weaving through the battlefield with acrobatic maneuvers that include zipping across rooftops and grinding along structures, all while confronting towering foes. The signature QTE‑driven special moves remain intact, adding a layer of tactical depth to the action.

What remains unseen is how Sora will collaborate with his long‑time companions. Donald and Goofy currently appear isolated from the keyblade wielder, leaving fans uncertain whether—and when—the trio will reunite on screen to showcase new party dynamics and synergy.

Kingdom Hearts IV is slated for launch on the Switch 2, PS5, Xbox Series X/S, and PC, though a definitive release date or window has yet to be announced.
