Leaf (Aoi in English, Vera in French)
The main character of the story, who ends up being late to get her first Pokémon and has to settle for a Clefairy. The series centers on her Pokémon journey.

- Precision F-Strike: In chapter 4, when telling Camper Liam to just get on with it:Leaf: Save your jive crap for Pokémon coordination!

- Whole Costume Reference: Her regular outfit is exactly like the one she wears in the Pokémon Craft DX manga and other promotional materials relating to Pokémon Red and Blue, and the Goldeen costume she wears in chapter 13 had previously appeared in "The March of the Exeggutor Squad".
Clefairy (Ana)
Leaf's starter Pokémon. She grows to like her trainer.
- Badass Adorable: Despite being rather feminine, she can hold her own in a battle.
- Cute Bruiser: Her base offensive attack is Pound.

- Talking Pokémon: Along with Pikachu, she's the first of Leaf's Pokémon to speak human language.
- Tomboy and Girly Girl: Girly girl to Pikachu's tomboy.
- Verbal Tic: "-pippi".
Pikachu (Lita in English and French, Makoto in Japanese)
An electric Pokémon who Leaf catches in Viridian City. Along with Clefairy, she stays out of her Poké Ball most of the time and instead prefers walking out in the open.
- Action Girl: On par with Misty in that regard, even!
- Badass Adorable: She may look cute, but she's got electric attacks which by all rights should be downright lethal if this wasn't Pokémon.
- Badass in a Nice Suit: When taking on Misty's Pokémon in chapter 13.
- Gratuitous French: She likes to remind people that "impossible n'est pas Français-pika" from time to time (for example, as her Pre Ass Kicking One Liner against Brock's Onix in chapter 4).
- Precision F-Strike: In chapter 7, after encountering one Zubat too many, she echoes the sentiments of many a Red and Blue player:Pikachu: Arceus-damned Zubat!
- Ridiculously Cute Critter: As is par for the course for most portrayals of Pikachu.
- The Rival: To Spearow. No surprise, since Electric-types and Flying-types are traditionally enemies.

- Shock and Awe: As can be expected of any Electric-type.
- Talking Pokémon: Along with Clefairy, she's the first of Leaf's Pokémon to speak human language.

- Tsundere: Particularly towards Spearow.

Spearow (Terminator in English and French, Zatoichi in Japanese)
A tough guy type who Leaf catches in Route 22. Easily irritable, and kind of a jerk most of the time.
- Anime Hair: He styles his hair like this.
- Feathered Fiend: Plays up this trait every chance he gets. Of particular note is chapter 3, when he's a bit too eager to battle the resident Bug-types in Viridian Forest.
- Jerk with a Heart of Gold: He may be belligerent towards his teammates, particularly Pikachu, and his fighting style may be overly aggressive, but at the end of the day, he cares very much about the whole team.
- The Rival: To Pikachu. No surprise, since Electric-types and Flying-types are traditionally enemies.
- Talking Pokémon: Like some of Leaf's Pokémon.
- Token Evil Teammate: Downplayed, but he's definitely more bloodthirsty than anyone else on his team.
- Verbal Tic: "-suzu".
Red (Aka in Japanese, Ross in French)
Another new Pokémon trainer going on a journey of his own. He and Leaf cross paths on multiple occasions.
- Adapted Out: Downplayed and, oddly enough, inverted considering the circumstances. As Red never appears in the games when Leaf is the player character, and as Leaf is the main character of this story, he's reduced to a supporting role compared to his role in Pokémon Origins.
- Friendly Rival: To Leaf, who he sometimes mentors and sometimes battles to test her skills.
- Playing with Fire: His Starter is a Charmander.

- Fair Cop
- Inexplicably Identical Individuals: As can be expected of them.
- Police Are Useless: Averted. When the Cerulean-based Officer Jenny finally lets Leaf enter the burglarized house, she's seen bringing in the ringleader of a Rocket recruitment scheme disguised as a Nugget Bridge challenge.

Misty Waterflower (Kasumi Mizuno in Japanese, Ondine Ste. Marie in French)
The Cerulean Gym Leader, who Leaf battles for the Cascade Badge. The youngest of four sisters, she inherited the Gym from her deceased father and is the most feared individual in Cerulean City, though she can be quite nice if you don't get on her bad side.
- Action Girl: The biggest one among the female Kanto Gym Leaders.
- Adaptational Modesty: She didn't wear pantyhose with her regular outfit, itself an example of this, in Pokémon: The Series.
- Berserk Button: Don't even think about assuming that just because she's a Squirtle Scout she goes door-to-door selling girl scout cookies. She in fact considers that to be an offensive stereotype of girl scout culture as a whole.

- Disappeared Dad: Her father was murdered by a Team Rocket grunt, and a subplot of the first and second seasons shows her trying to avenge him on the one that did the deed.

- Fiery Redhead: Ironic considering she's a Water-type specialist.
- Insult Backfire: At times, she's been known to take insults in stride. For example, in chapter 10:Leaf: What kind of idiot would wear pantyhose when swimming?
Misty: The kind of idiot that likes her clothes waterproof. - Irony: She's the least interested in the performing arts out of all the females in her family, and yet she knows some ballet, even earning a merit patch following a recent monthly skills test, and has learned a few parlor tricks from her older sister Lily.
- Little Miss Badass: There's a reason she made history as the youngest Gym Leader to date, being inaugurated some weeks before her 10th birthday.
- Making a Splash: She's a Water-type specialist, what did you expect?
- Noodle Incident: She once tangled with Mewtwo when Team Rocket used one of her friends as bait in an attempt to indirectly get rid of her.

- Pink Means Feminine: Word of God is that pink is her theme color.

- School Uniforms are the New Black: Downplayed. She's seen in casual clothes frequently enough (particularly her regular outfit) when not participating in regular Squirtle Scout activities, but for occasions such as the S.S.

- Tomboy and Girly Girl: Tomboy to Leaf's girly girl.
- Tomboyish Ponytail: As usual, her hair is normally styled like this.
- Tomboy with a Girly Streak: She's ironically more graceful and balletic than Leaf (to the point where she has a Dancing Merit Patch—it helps that she's been having ballet lessons ever since she joined the Squirtle Scouts), and in fact when we're introduced to her one episode after her Early-Bird Cameo, she's practicing gymnastics just outside of Cerulean Gym. In addition, she happens to enjoy Sailor Moon, though it's more a product of being a '90s girl than anything (per Word of God, the series was still being broadcast, and the comics still being written, at the time Clefairy Tales takes place).
- True Blue Femininity: As with other Squirtle Scouts, she wears a blue uniform.
- Why Did It Have to Be Snakes?: As is her anime counterpart, she's an entomophobic. However, she does agree with Erika that Butterfree is pretty, for a Bug-type.
- You Killed My Father: Spoken to the plainclothes Rocket in chapter 11. But then, she was just taking her anger out on Team Rocket as a whole simply because someone in their ranks did the deed.
Lt. Mathias Surge (Major Bob Tesla in French)
The Vermilion Gym Leader, who Leaf battles for the Thunder Badge. He's an Army veteran who was originally from Unova.

- Noble Bigot: She retains her shades of this from the original games, but here she also gives a pass to those who can learn Grass-type moves, including Butterfree, which she describes during the S.S. Anne party as "the prettiest Bug-type you'll ever meet", a sentiment with which Misty, a known entomophobic, agrees.
- True Blue Femininity: Word of God is that blue is her theme color, and she even wears a blue dress to the S.S. Anne party.
- Whole Costume Reference: She wears Cinderella's butterfly-themed ballgown from Disney's 2015 film adaptation to the S.S. Anne party. In-universe, she mentions having gotten the idea for the dress from watching Disney's animated adaptation while designing a Butterfree-themed perfume.

- Showgirl Skirt: She wears a Goldeen costume when performing as a Stage Magician.
