Grandfather of Green and Daisy, he's full name is Samuel Oak. He is a researcher who invented the Pokédex and sent out Red on his journey. He has a long history with Agatha, Pryce, and the Johto Daycare couple.

• Distressed Dude: He's been captured twice, and has to be rescued by his grandson Green.
• I Was Quite a Looker: Revealed on chapter 76.
• The Mentor: To Red, Green, and Blue.

Daisy Oak

Green's older sister.

• Cool Big Sis
• Hot Scientist
• Ship Tease: With Bill.

Bill

The technical genius who invented the storage system.

• Butt Monkey: Among other things, Pika seems to enjoy shocking him for no good reason.
  • Throw the Dog a Bone: How else could he get a girlfriend?
• Gadgeteer Genius
• Kansai Regional Accent: And is given a Southern accent in the English version. Hardly anybody can understand him at all. It dies down as the series goes on.
• Ship Tease: With Daisy. This exchange from FRLG doesn't help:
  Green: You're...not with my sister today?
  Bill: (nervously) Oh, uh...Daisy's at home.

Brock

The Gym Leader of Pewter City, he trains with Rock Pokémon and is also a security guard for the Pewter City Museum.

• Eyes Always Shut
• Walking Shirtless Scene: Only in the RGB arc. He starts wearing shirts after that.
  • He was still shirtless in the beginning of Yellow arc, though they should have made it consistent.
• Worthy Opponent: He chooses a worthy opponent through a series of battles before his actual gym battle.

Misty

The headstrong Gym Leader of Cerulean City, specializing in Water types. She is perhaps Red's first real ally and gave him her Gyarados, which he still keeps in his party to this day.

• Aborted Declaration of Love: Misty was about to confess to Red the day before he was going to take his Gym Leader test, but decided against it because she saw him talking to Yellow. She did seem to put some thought into it before deciding it wasn't the right time.
• Action Girl
• All Love Is Unrequited: Her crush on Red.
• Big Fancy House: Has one.
• Can't Catch Up: Acknowledges this at near the end of the GSC arc; she knows that she isn't meant to fight the final battle against the Mask of Ice, but takes comfort in knowing that the Pokemon that she gave to Red (her Gyarados) and Yellow (her Omanyte, which evolved into Omastar) will be able to help out.
• Curb-Stomp Battle: Against Red when he stayed at her mansion; notable in that she was the first person to do so.
• Fiery Red Head
• First Girl Wins: Averted, as she is the first girl Red meets on his journey and she never got the chance to confess her feelings to him. She couldn't bring herself to do it when she saw him and Yellow together the first time, and the second time Gold kind of kidnapped rescued him. Granted, the first time, she really should've taken her chances, as Red didn't know Yellow was a girl yet.
• Heroes Want Redheads: Inverted with Red.
• I Just Want to Be Special: More that she wants to be useful rather than special, but she understands and is frustrated by the fact that she can never be more than support to Red and the others.
• Interrupted Declaration of Love: By Gold at the end of GSC arc.
• Jumped at the Call: Was very eager to fight alongside Suicune as its partner, as it fulfulled her desire to finally be more useful and involved in stopping the crises that Team Rocket was causing. Unfortunately for her, The Call realized it phoned the wrong number, hung up, and redialed for Crystal.
• Making a Splash
• Pimped Out Dress: She wears one when she brings Red to her Big Fancy House.
• Plucky Girl
• Sidekick Glass Ceiling: She's a capable Trainer and Gym Leader, enough so that Suicune designated her as a worthy partner after battling against the Gym Leaders of Kanto to find someone worthy. Unfortunately, her status as an ally of the main cast rather than as a full-fledged hero keeps her from effectively battling and ending the crises herself, something she acknowledges that only the Dex Holders can do. But she'll be damned if she doesn't put up a good fight doing so.
• Tearful Smile: A couple of times, most notably when she finally gets to talk to Red again at the end of the GSC arc.
• Tomboy
• Tsundere: Different from Misty in the anime in that she's a very mild Type B, with her tsun tendencies being played up almost exclusively in the RGB arc.

Erika

• The Archer: Practices archery and sometimes uses her arrows to launch her Pokeballs.
• Green Thumb
• Kicking Ass in All Her Finery: Wears a kimono and battles with elegant style. It helps that she's also The Leader.
• Lady of War: When the need to fight arises.
• Lovable Alpha Bitch: Often makes condescending remarks towards other trainers and her opponents and has a rather snooty attitude overall, but is genuinely kind towards those she considers her companions, like Brock, Misty, and several of the Dex Owners, once they earn her trust.
• The Ojou
• Secret Test of Character: Arguably, what she did to Red when they first met and he was hell-bent on rescuing that Eevee.
• Shipper on Deck: Red x Misty, apparently.
• Silk Hiding Steel
• Spirited Young Lady
• Straight Arrow: She sometimes fits her Pokéballs at the tip of her arrows and shoots them to launch them.

• The Leader: Of the Kanto Gym Leaders overall.
• Yamato Nadeshiko: Has some of the personality traits.

Blaine

An old scientist who used to work for Team Rocket, this fire specialist defected offscreen as he got sick of working for them.

• Badass Mustache: Hilariously, at one point he reveals he wears a fake one because he accidentally burned off his real one during training.
• Body Horror: His DNA mixed with Mewtwo's while he was creating it, leading to him developing cancerous growths that would eventually take over his body. He got better.
• Cool Old Guy
• Cool Shades
• Heel Face Turn: Hearing of Red's heroic exploits was a big motivation for him to skip out on Team Rocket and join the good guys.
• Kick the Dog: This was pretty much Blaine's old job at Team Rocket, as he was to experiment on Pokémon into making them stronger, which led them to either go insane or simply be in extreme pain.
• Playing with Fire
• Shout Out: At one point in the Yellow arc he wears a disguise that resembles the anime version of him.

Janine

Koga's daughter, who takes over the Fuschia Gym after his disappearence. Like her father, she specializes in poison types. She also works as a part-time freelancer ninja.

• Badass Normal: She's capable of rather impressive physical feats, going with the whole ninja theme. (Although she does seem overly fond of the whole hanging upside-down on the ceiling thing.)
• Disappeared Dad: She wants to see him again, as his disappearence left her not knowing what to do with her future. Due to this, most people tend to pair her with Falkner, who has similar father issues.
  • It also helps that they befriend each other after their battle.
• Doppleganger Spin
• Ninja: Like her father, she uses her Pokémon for ninja-esque techniques and outfits her Pokéballs into shuriken.

• Unwitting Pawn: To Agatha after outliving his usefulness.
• You Have Outlived Your Usefulness: See above.

• Crouching Moron, Hidden Badass: She does show a surprising amount of skill when battling the fake ice Suicune.
• Curb-Stomp Battle: She is the recieving end of this as Misty defeats her rather easily in only a few pages, which is kind of sad as the other Gym Leader battles took at least a chapter. Well, Suicune didn't bother with her for a reason...not to mention considering it chose Misty as its partner as well...
• Girlish Pigtails
• Non-Elemental
• Took a Level in Badass: She's alot stronger in the "Heart Gold & Soul Silver" arc.

His "starter" is Ruby's Ralts, Ruru, who was eventually returned to her true trainer. His first Pokémon is a Kecleon.

• Adaptation Dye Job: In the games Wally has Blue Eyes.
• Badass Adorable: In fact, many wanted him to be the third Hoenn Dex Holder instead of Emerald.
• Curtains Match the Window: Green hair and green eyes.
  • And green Pokémon! All six of them, not to mention he was important in waking Rayquaza! It's never commented on in the comic itself, but the tradition is carried on in the webcomic Pokémon-X, which flanderizes it into an incredible obsession with Pokémon that have ANY green at all on them.
  • This was to mark that Wally is the supposed third hero of the RS saga but the writers decided to just make a new character midway. At least they still gave Wally some plot related action.
• Dragon Rider: Straightest example here. He has a Flygon.
• Handicapped Badass: The kid appears to have awful asthma, and it gives him some complications near the end of the arc when he trained under Norman en route to Rayquaza. Does he let that stop him?
