5 Supporting Characters Who Must Return in Kingdom Hearts 4

Summary

Speculation about the return of characters in Kingdom Hearts 4 has increased, especially with the introduction of the new world Quadratum.
Characters like Axel/Lea, Isa, Young Xehanort, Luxord, Marluxia, and Ventus have potential story arcs and connections that could fit into the new game.
The mysteries surrounding certain characters, like the enigmatic Ventus, make their potential returns in Kingdom Hearts 4 more intriguing and unpredictable.

With Kingdom Hearts 4 somewhere on the horizon, speculation surrounding the upcoming Square Enix sequel has only grown. Once again focused on protagonist Sora, all that's known of the game is that it will be set in the strange, new "fictional world" of Quadratum. As the wait for Kingdom Hearts 4 has left fans searching for hints about the future in the series' past few releases, some characters have started to seem more likely to return than others.

With a somewhat convoluted cast of many characters over the years, there are several possibilities regarding who could make their return. As an "afterworld" that Sora has entered after making the ultimate sacrifice, Quadratum may actually serve as an afterlife of sorts. With the open-ended nature of allowing fallen characters in new ways, the returning faces of Kingdom Hearts could end up surprising players more than ever.

Axel

Will Lea and Isa Find Their Missing Friend?

Axel's redemption as Lea was a surprise of its own, but a twist of events that may have actually shocked many fans was the redemption of Saix when he returned to his original self as Isa and finally reunited with Lea. A discussion between the two revealed the story of their unknown missing friend, a girl from Radiant Garden who some fans have theorized could be the true identity of the Nameless Star. Lea’s arc may be quite complete, but he’s sure to have some involvement if the mystery of the Nameless Star in KH4 ends up connected to him after all.

Young Xehanort

A 14th Life is a Chance for the Dark Seeker to Truly Redeem Himself

Xehanort once told Eraqus that he wanted to have 13 lives to change the world, but then another one in order to watch the aftermath. With the art of him in Shibuya from Kingdom Hearts: Dark Road and Tetsuya Nomura’s comments on the end of the Dark Seeker Saga not necessarily meaning the end of Xehanort, there's a chance that he could reappear within Quadratum as an ally to Sora instead of an antagonist. If Quadratum is truly some kind of afterlife in the KH universe, some fans have even considered that Sora, Stretlitzia, and Xehanort could form a new trio.

Luxord

The Mysterious Gambler's Connections Remain Unknown

Between his mysterious “Wild Card” gift to Sora in Kingdom Hearts 3 and his ominous presence as Yozora's driver, it's highly likely that Luxord still has a bigger role to play. Given his mysterious past when compared to the revelations surrounding the histories of most other Organization 13, there’s a good chance that Luxord’s backstory could have ties to Verum Rex or Quadratum as a whole. Even if Luxord himself doesn’t appear, the Wild Card has been confirmed to play some kind of role in the Lost Master Arc.

Marluxia

The Organization 13 Traitor Already Has Deep Ties to Kingdom Hearts 4

After remembering his past as Lauriam in KH3, Marluxia’s connections to the Union X story are likely to be explored further in Kingdom Hearts 4. Considering the fact he used to be a keyblade wielder along with Elrena, the human form of Larxene, there is certainly more to the Chain of Memories antagonist than has been revealed so far. Now that Strelitzia, his younger sister, appears to be an important character in Kingdom Hearts 4, it’s even more likely that Marluxia will receive some form of new development.

Ventus

Birth by Sleep's Most Enigmatic Hero Still Has Secrets

After being revealed to have existed since the time of Union X and a part of the events in Daybreak Town, the mystery surrounding Ventus hasn’t yet been resolved. While there is still a case to be made as to why Ventus shouldn’t return in Kingdom Hearts 4, the blank period between his end in the Union X narrative and the lead-up to Birth by Sleep has created an intrigue around him that could make Ventus’ return more interesting than the more predictable circumstances surrounding both Terra and Aqua.
