This is a listing of the supporting cast originating from Final Fantasy and other Square-Enix titles that appear in the Kingdom Hearts series. Visit here for the main characters index.
For the
Final Fantasy characters, the same characterization tropes generally apply as in their original games.
"No matter how far away we are, our hearts will bring us together again."
A resident of Radiant Garden prior to its destruction, she ends up in Traverse Town instead. In
Kingdom Hearts II, she (like most of Traverse Town's residents) moves back to Hollow Bastion and assists in its rebuilding.
- Cordon Bleugh Chef: She's one of these in the manga adaptations.
- Demoted to Extra: She and Cid don't take part in fights, despite them being playable characters in FFVII.
- Glamour Failure: In Chain of Memories, she's the only one who seems to be aware that she and the others are constructs of Sora's memory.
- The Heart: Of the Hollow Bastion Restoration Committee.
- Lethal Chef: In the manga adapatations. She makes her own homemade beverages and refreshments, but always adds the wrong ingredients.
- Japanese Pronouns: "Watashi".
- The Medic: Heals Yuffie during the Heartless invasion, and teaches Sora the highest level of Cure in the first game.
- The Other Darrin: Played by Mandy Moore in the first game. She was replaced with Mena Suvari for Kingdom Hearts II.
- Princess Curls
- Ship Tease: With Cloud, like in the original game.
- Spared by the Adaptation
"All my life, I've been protecting others... And now, there's no one left to protect."
"This is my story. And you're not a part of it."
A warrior summoned by Hades to kill Hercules in
KH2, he refuses and joins with Sora instead. He serves as Sora's partner in Olympus Coliseum in the game.
- Badass: Heh, it wouldn't be Auron if he wasn't badass. One scene of his battle with Hercules has him swing his katana with one hand, and Herc has to use both hands to hold him off. Granted he's tired from all the fighting up that point, but still.
- Back from the Dead: Well, kind of.
- Brainwashed: Hades forces Auron into servitude by stealing Auron's willpower and imprisoning it into a statue of his likeness. Auron is then made to fight Hercules in a deathmatch. Luckily, Sora & co. save the day, and Hades gets utterly screwed.
- Deadpan Snarker: "No wonder no one wants to die."
- Did You Just Flip Off Cthulhu?: Does this to Hades.
- Good Scars, Evil Scars: Still has that scar over his (missing) eye.
- Japanese Pronouns: "Ore".
- Katanas Are Just Better: Huge katanas, that is.
- Mythology Gag: Just about everything he does references FFX.
- Pre Ass Kicking One Liner: "No wonder no one wants to die," he said to Hades when he was bragging about being the "Lord of the Dead". No one could hope for a more badass intro.
- The Stoic
- Tall, Dark and Snarky: It's Auron.
- You Shall Not Pass: Does this to Cereberus. Subverted when Sora returns and the two kick Hellhound rear in a Back-to-Back Badasses moment.

"Don't call me gramps!"
The owner of the Traverse Town accessory shop and a Gummi Ship expert. He saved Leon and the others during the destruction of Radiant Garden. He returns to Hollow Bastion with his fellow
Final Fantasy characters in
KH2, and is responsible for the Claymore security system.
"Looking for your light? Don't lose sight of it."
"I'm looking for someone. Hades promised to help. I tried to exploit the power of darkness, but it backfired. I fell into darkness, and couldn't find the light."
A brooding swordsman who is busy trying to work out his dark past. He first appears as a hired thug for Hades as part of one of his many attempts on Hercules's life, but joins the rest of the Hollow Bastion gang by the end of the first game.
- Anime Hair: It's a staple. Was toned down in II to match his appearance in Advent Children.
- Badass Cape: In the first game, due to Cloud being heavily inspired by Vincent Valentine.
- Back-to-Back Badasses: With Leon before The War Sequence. Their snark-fest doubles as a playful jab to the Fandom rivalry between Cloud and Squall.
- BFS: Wouldn't be Cloud without one.
- Bonus Boss: Via Coliseum cups.
- Celebrity Voice Actor: Voiced by Steve Burton, that dude from General Hospital.
- Good Wings, Evil Wings: A single black bat wing that appears when he uses his his version of Omnislash, mirroring Sephiroth's constantly-present wing.
- Guest Star Party Member: Just before The War Sequence, the player fights alongside each of four Final Fantasy characters briefly.
- Hired Gun: Was this for Hades in the first game for a short time. He was hired by him to kill Hercules, and then Sora, in the Olympus Coliseum. He broke his contract with Hades when he pulled an You Have Failed Me card on him after his failed fight with Sora, whether it's by losing to him, or refusing to finish him off after beating him.
- Japanese Pronouns: "Ore".
- Mythology Gag: He uses his various Limit Breaks from FFVII, like Braver and Omnislash.
- Only I Can Kill Him: His relationship here with Sephiroth, it seems.
- Ship Tease: With Aerith. Also with Tifa in the second game, depending on your interpretation of what Tifa actually is in that game.
- The Stoic: Even more so than he was in his original game.

"We may never meet again, but we'll never forget each other."
A resident of Radiant Garden, he changed his name to Leon after its destruction.
He leads the Hallow Bastion Restoration Committee in an effort to return his home to its former glory, if not something better.
- Animal Motifs: His lion motif is as omnipresent as ever; in addition to his name and his clothes, he provides Sora with the Simba summonstone and the Lionheart and Sleeping Lion keychains.
- Back-to-Back Badasses: See Cloud's entry above.
- Big Brother Mentor: For Sora.
- Bonus Boss: Appears in a few Coliseum matches.
- Character Development: He's quite gruff and taciturn in the first Kingdom Hearts game, but notably more relaxed in the second. Getting back to Radiant Garden presumably helped. This reflects his Character Development in FFVIII.
- Cool Gunblade
- Defrosting Ice King
- Mr. Fanservice: May in fact be sexier than his VIII self, depending on the viewer. Must be the belts. And the extra seven or eight years. And the new name. And the longer hair.
- Good Scars, Evil Scars: The kind that stick for all of time.
- Guest Star Party Member
- Heads I Win, Tails You Lose: When Sora fights him during their first encounter in Traverse Town, either Leon wins and Sora passes out, or Sora wins... and passes out from the effort.
- Improbable Weapon User: He fights with his famous Gunblade.
- Japanese Pronouns: "Ore".
- Laser Blade: His Gunblade can turn into one. It's an 'effin big one too, no doubt a Shout Out to his Blasting Zone Limit Break.It's also the inspiration for the Bladecharge command style.
- The Leader: Of the Restoration Committee.
- Mythology Gag: As mentioned above, when you get his HP low enough, he uses a version of Blasting Zone just like in FFVIII, His spin attack is also reminiscent of his Fated Circle and his jump slash is much like Rough Divide as well.
- Leon being from Radiant Garden may be a reference to Squall being from Balamb Garden in Final Fantasy VIII.
- Both of his character designs include a stylized pair of red wings on the back of his jacket, a visual reference to the white angel wings on the back of Rinoa's jacket in FFVIII. In addition, the red Griever insignia (a lion-headed cross) on the sleeve of his jacket may be a callout to the red cross on Seifer's FFVIII Badass Longcoat.
- The Other Darrin: David Boreanaz in the first game, later replaced with Doug Erholtz.
- Pet the Dog: In the first Kingdom Hearts, he expresses concern over the lost Dalmatian puppies (literal dogs), and later gets Geppetto and Pinocchio a house when they arrive in Traverse Town.
- Playing with Fire: His only long-range attack (unless you count the Laser Blade) is a fire spell.
- Pretty in Mink: His appearance in II restores the trademark fur collar.
- Running Gag: Aerith constantly offers him her homemade beverages, and he constantly refuses, aware of its flaws.
- That Man Is Dead: Refuses to call himself by his real name of Squall because of his guilt over what happened to Hollow Bastion.
- Shell-Shocked Veteran: In the first game it's clear that he suffers from the memories of Hollow Bastion's destruction at the hands of the Heartless. In the second game, he's lightened up while helping to rebuild it (see Character Development above).
- The Stoic —> Sugar and Ice Personality
- Supporting Leader: He is the leader of the Hollow Bastion Restoration Committee.
- Tall, Dark and Handsome
- Team Dad
- Too Many Belts: He wears them on his arms!
- Wake Up Call Boss: In the first game.

"That was undeniable proof that we totally owned you lamers!"

"My life is a chip in your pile. Time to ante up."
An inhabitant of Twilight Town, he's the Struggle champion in the digital town but is just another competitor in the real world.
- Adaptational Attractiveness
- Badass Cape/Badass Longcoat: Square-Enix combines two of their favorite costume tropes at last. Setzer wears his trademark coat around his neck with his arms out of the sleeves, treating it more like a cape.
- Bragging Rights Reward: The Champion Belt you win for beating him gives 20% resistance to Fire, Ice, Lightning, but you won't be encountering enemies that use those attacks for some time. It's actually better to lose to him and get the Medal, which gives a minor attack boost so it'll be useful immediately.
- The Fighting Narcissist
- Flanderization: His showy-ness and arrogance is played up big time.
- Creator Backlash: And Square-Enix jabs at this in Dissidia: Final Fantasy where Setzer and Shadow appear as in-game tutors — Shadow tells Setzer not to bribe opponents to win, and Setzer protests he would never do such a thing.
- Then again, the only time we actually see him is in the computer simulation... so much like Seifer, the real one wouldn't quite be like that.
- Miles Gloriosus: For all his boasting and showing off, Setzer is a very poor Struggle fighter.
- Hair Flip: When entering a battle.
- Spin Attack
- White-Haired Pretty Boy
