This was originally in chapter 6, but I decided to make this in its own chapter.

Kingdom Hearts Series:

Yeah, I know some of you were waiting for this! The series that crosses over Disney, Anime, and Final Fantasy with a confusing story and an even more confusing timeline in one big, wacky fanfiction made into a video game... and I love it for that.

So Owl House is an interesting case because we have no idea what game it would take place in, so I'll just say it happens in either KH 1.

The Owl House's world would be called "The Boiling Isles" and would be placed in-between Atlantica and Neverland with a high difficulty of 8 stars.

In KH 1; Sora, Donald, and Goofy discovers the Boiling Isles where they meet Luz Noceda. This part of the game will be loosely based on the climax of the first Owl House film where Sora and friends help Luz on a quest to free Eda from the clutches of Emperor Belos while fighting hordes of the heartless. Luz will have her own set of abilities.

...

Luz's Abilities:

Staff Swing/Bash (Strikes enemies/Default Attack. Cost: 0 MP)

Staff Shockwave (Knocks back surrounding enemies with a chance to Stun/Special Attack. Cost: 2 MP), Light Spell (Has a very high chance of stunning enemies/Special Attack. Cost: 1 MP) Cure Potion (Use potions packed with Cure effect. Defense Skill. Cost: 1 MP), Jackpot, MP Rage, MP Haste.

...

We're first introduced to Emperor Belos as a member of the Council of Villains alongside Maleficent, Hades, Jafar, Ursula, Captain Hook, and Oogie Boogie. All have the goal of defeating the Light and taking full control of the Kingdom Hearts and the Heartless for universal domination. Belos will mostly interact with Maleficent only when he tells her that he holds no trust in her and if she even tries to betray him, he'll destroy her which amuses Maleficent.

When Sora and friends arrive in the boiling isles, they encounter Luz Noceda (1990s Debut Version) who is fighting off surrounding heartless in front of the Owl House with Hooty knocking enemies away from her only to become overwhelmed too. Sora, Donald, and Goofy jumps in and helps defeat them. Luz then speaks to Sora; showing her surprise that another human is in the Isles, thanks him for the assist, and explains that she was on the way to save Eda from Belos until the Heartless came out of nowhere.

Similar to characters from other worlds, Luz can join the party by replacing Donald or Goofy.

The Owl House can be entered with only to rooms available for exploration (living room, kitchen, and Luz's room). You can talk to King who's sitting on the couch who thanks you for helping Luz while Hooty, who's at the door, thanks them as well and then begins to speak about crazy things. The living room will also holds a save point.

The second stage is Bonesborough which is crawling with the heartless. There will be two exclusive heartless of this world; one that looks similar to the emperor's guards that uses a blade as a weapon and another that has the features of an owl which can fly through the air and dive down to strike Sora and Co. Both are named Emperor Guard and Owl Heartless respectively.

The third stage is he front of Belos' castle where you have to cross the bridge leading towards the entrance to the castle where you have to fight a bunch of heartless along the way. But be careful! Under the bridge lies a giant bed of spikes which will earn an automatic death if fallen onto.

The final stage will be inside of Belos' castle which has three floors for Sora and friends to explore.

The first floor is where Sora, Luz, and Donald/Goofy will be ambushed by heartless only to be saved by Lilith. Luz will show her distain towards Lilith for her betrayal against Eda which the latter will understand completely and begs Luz to not only forgive her, but to also trust her to help save Eda. Luz reluctantly agrees. The first floor will have a save point and Sora will be able to talk with Lilith who shows confusion that there's a second human but encourages him anyways.

The second floor is where you fight the Owl Beast who has been set loose by Belos to destroy Sora and Luz. The Owl Beast's moves consists of charge attacks, claw swipes, and fang gnashing. The owl beast can also use its wings to fly through the air and smash land wherever Sora or Luz is located, creating a shockwave in the process. The owl beast only has two bars of health and once it's defeated, it'll fall on its side. Luz will run up o the beast and pulls out an elixir bottle from a bag only for it to do nothing. Lilith then appears with an artifact that she says can cure any curse no matter how powerful. The owl beast then shrinks and transforms to reveal Eda.

After a small reunion between Luz & Eda, the former is reminded that Belos is on the top floor of the castle; his throne room. Eda tries to stand and face Belos herself but is too weak to move, so Luz elects herself to go instead of Eda whom Lilith stays behind with to keep her safe.

The final floor will show Belos' throne room and reveals the beating heart of the Titan hanging from the ceiling. Sora and friends begin battling Belos who uses different forms of magic such as fire, ice, plant, and electricity. At certain points in the fight when Belos takes enough damage, he surrounds himself in an orb which protects him from attacks and allows Belos to heal himself. While this is going on, Kikimora and some heartless appears and starts attacking. The heartless are the same as before, but Kikimora is much quicker and has more health (think of Lock, Shock and Barrel's mini-fight from the Halloween Town world). After Kikimora is beaten, Belos will leave his orb and continue the fight. This will happen one or two more times during the fight, but they key is to finish off Kikimora and the heartless as quick as possible so Belos won't regenerate a lot of health.

After the final blow is struck, Belos will stumble backwards as his body begins to illuminate in a bright late. Belos will let out a scream of anguish before his body explodes with only his mask being all that's left of him. Maleficent will make a brief appearance as it's revealed that she was watching the fight the whole time and gloats about Belos' defeat before vanishing.

Suddenly, the keyhole to this world appears on the heart of the Titan which allows Sora to use his keyblade to seal it closed. The throne room then becomes explorable with Luz, Eda, Lilith, and King in the room with Sora. Luz and Eda thanks Sora for his help. Lilith also thanks Sora and promises that she will right the wrongs that Belos has caused.

Sora is awarded a new keyblade called "Wild Magic" which looks similar to Eda's staff which has a tiny wooden Owlbert as a keychain. It boosts magic while slightly decreasing attack power.

Sora will also be granted a new assist gem that could be one of three characters:

1.) King:

Once summoned, King jumps from enemy to enemy which causes then to become stunned. For bosses, King takes a small percentage of health away from them.

2.) Hooty:

Hooty pops from the ground and strikes enemies from all around. For bosses, Hooty will have a small percent of damage against them.

3.) Owlbert:

Owlbert flies through the air and drops health & magic orbs for Sora and Co. The more damage Sora does to enemies, the more orbs Owlbert drops.

...

During the end credits we see Eda, Luz and King all sitting next to each other on Eda's staff as they overlook the isles.

The original voice actors of Luz, King, Eda, Emperor Belos, and Lilith from the 90's film returns to their roles.

Willow, Gus, Amity, and other characters don't make an appearance.

Character Pages:

Along the journey, Jiminy Cricket writes down a bio of any character whether good or evil in the pages of his journal. Here's my interpretations:

1.) Luz Noceda:

A fourteen-year-old girl with an active imagination and a witch-in-training. Luz can be headstrong and sarcastic, but she makes it up with her kindness, bravery, and her determination to master all forms of magic.

Luz first arrived to the Boiling Isles in "The Owl House" (1997).

2.) Eda Clawthorne:

The most powerful witch in the Boiling Isles and Luz's mentor; Eda the Owl Lady is wanted by the Emperor for her wild ways, but she isn't truly a criminal. After years of suffering from a dark curse, Eda has finally been freed.

Eda took Luz under her wing in "The Owl House" (1997).

3.) King:

A small demon who looks strikingly similar to a small dog. King's as loveable as can is feisty, but hates being called cute. While he can be arrogant, King is always ready to help a friend-in-need.

King came onto the scene in "The Owl House" (1997).

5.) Emperor Belos:

The tyrannical ruler of the Isles who wields powerful magic who's past is a mystery. Belos is extremely prejudice towards wild witches like Eda and will do anything to get them under his control. He joined Maleficent's alliance only to be defeated by Sora.

Emperor Belos ruled the Boiling Isles with an iron fist in "The Owl House" (1997).

6.) Lilith Clawthorne:

Eda's older sister. Lilith was originally the captain of the Emperor's Coven and was loyal to Belos until she found out how evil he really is. Lilith is also the one who cursed Eda when they were younger, but has since cured her sister and the two have made amends.

Lilith chose the path of good in "The Owl House" (1997).

7.) Kikimora:

Belos' loyal servant. While Kikimora may not seem like a threat, she is smart and calculating and will do anything to please her Emperor. She ran off after Belos was defeated.

Kikimora served Emperor Belos in "The Owl House" (1997).

8.) Hooty:

A somewhat snake-like owl head that resides on the front door of Eda's home. He's very energetic and has a loud voice though he almost sounds like King Mickey.

Hooty stretched onto the big screen in "The Owl House" (1997).

9.) Owlbert:

Eda's palisman which comes to life and has a mind of his own. He's very friendly and loves having his head nuzzled. He's also the reason why Luz found the Boiling Isles in the first place.

Owlbert took to the skies in "The Owl House" (1997).

10.) The Owl Beast:

Eda's cursed form. A mindless, savage creature with sharp claws and even sharper teeth. Thankfully Eda is cured so this monster will never see the light of day again.

The Owl Beast first appeared in "The Owl House" (1997).

This next time that Owl House will make another appearance is in Chain of Memories which might be its final time appearing unless the sequel movie gets adapted like how The Return of Jafar was in KH 2. If it did then Willow, Gus, Amity, and the Blight twins would appear.
