Kingdom Heartsbegan as a crossover between Square Enix and Disney properties, so there were a lot ofFinal Fantasycharacters in the first few games. However, they haven’t been in the series much as time has passed by. While many fans hope to see characters like Cloud, Sephiroth, Leon, and Cid return inKingdom Hearts 4, it is possible thatFinal Fantasycharacters will, once again, not make an appearance.

IfFinal Fantasycharacters aren’t going to appear inKingdom Hearts 4, Square Enix has other properties that would make wonderful additions toKingdom Hearts. In fact, some characters from their other games have already been introduced in previousKingdom Heartstitles.

Kingdom Hearts Precedent for The World Ends With You

The World Ends With Youis an underrated series by Square Enix that currently only has two games. However, the main characters of the original installment replacedFinal Fantasycharacters inKingdom Hearts: Dream Drop Distancewhen Sora and Riku went to Traverse Town.The World Ends With Youcharacters helped Sora and Riku out during their appearances in the game, and they all became good friends with each other throughout the story.

InThe World Ends With You, Neku, Shiki, Beat, Rhyme, and Joshua are from Shibuya, a part of Tokyo thatKingdom Hearts 4’s Quadratummay be inspired by. In fact, Sora fought Yozora on the 104 Building, an iconic location in Shibuya, which could potentially hint that Neku, Joshua, Rhyme, Shiki, and Beat will return inKingdom Hearts 4, along with the characters that were introduced inNeo: The World Ends With You.

Kingdom Hearts 3 Schwarzgeist

Einhander’s Schwarzgeist Was A Secret Boss In Kingdom Hearts 3

Long beforeKingdom Heartsbecame one of Square Enix’s most popular franchises, Square developed a game calledEinhander, which released in 1997 on the PlayStation. It was a sci-fi shoot em up inspired by Greek mythology in which players attack spaceships. InKingdom Hearts 3, players could fightEinhander’s Schwarzgeist during a Gummi Ship segment.

Schwarzgeist is not the type of boss battle thatKingdom Heartsfans would have expected to go up against, especially as this was the first time that there was a Gummi Ship secret boss. Perhaps this encounter wasn’t as random as some many have initially believed ifEinhanderbecomes relevant to the series inKingdom Hearts 4.

Dragon Quest 11 characters

Dragon Quest Could Fit Kingdom Hearts

WhileDragon Questhas never appeared inKingdom Hearts, unlikeEinhanderandThe World Ends With You, it would be wonderful to see another one of Square Enix’s popular franchises cross over withKingdom Hearts. Asthere are so manyDragon Questgames, the series offers a lot of locations that could inspire worlds for Sora and otherKingdom Heartscharacters to go to.

There are also many characters thatKingdom Hearts' protagonists could easily become friends with and bosses that would be amazing to fight against. However, seeing as how playable characters inDragon Questare usually created by the players or are silent protagonists, the supporting cast would likely join theKingdom Heartsheroes on their journey, rather than the player characters.

NieR’s Similarities With Kingdom Hearts

While theNieR/Drakengardseries was another underrated Square Enix franchise when it first began,NieR ReplicantandNieR Automatahave become very popular titles, both of which share a lot in common with theKingdom Heartsgames. CertainNieRcharacters, as well as enemies known as Shades, are rather similar to the Heartless and Nobodies fromKingdom Hearts.

Some fans considerNieRto be a more mature version ofKingdom Hearts, so it would very interesting to see the characters from each series interact with one another. Sora could instantly befriend the main characters ofNieR Replicant, while a character likeRikuor Axel would easily fit inNieR Automata. There are so many Square Enix franchises that should crossover intoKingdom Hearts, and it will hopefully happen inKingdom Hearts 4, whetherFinal Fantasyis in it or not.

Kingdom Hearts 4is currently in development.
