Gym Leader Sabrina
In Pokémon HeartGold and SoulSilver, Sabrina reprises her role as the gym leader of Saffron City. Her own psychic abilities are tied to her affinity for Psychic-type Pokémon, and if you defeat her she will give you the Marsh Badge. Though much of her appearance changes from title to title and platform to platform, Sabrina retains a similar hair color no matter what.
Professor Rowan in Pokémon
“Hello there! It’s so very nice to meet you! Welcome to the world of Pokémon!” Professor Rowan, located in the Sinnoh region, is a specialist in the field of Pokémon evolution and contemporary of Professor Oak and mentor to Professor Sycamore. Rowan is sometimes perceived as mean because of his stern personality, but he is actually kind and patient. He’s quite a snazzy dresser.
Gym Leader Flannery
Specializing in Fire-type Pokémon, Flannery (voiced by Lisa Ortiz in the anime) is the resident gym leader of Lavaridge Town. Her gym also serves as the local hot spring. Her wild red hair can be replicated with a lot of patience and even more hair spray, and the flame logo on her shirt can easily applied to a plain tee using paint.
Professor Juniper in Pokémon
Professor Juniper is the first female professor in the Pokémon series. Her specialisation is Pokémon origin and she is an old friend of Professor Oak, because who isn’t, right? Her clothes are pretty plain, especially when compared to the other Pokémon Profs.
Professor Elm in Pokémon
Professor Elm was Professor Oak’s top student. He studies Pokémon abilities and specialises in Pokémon breeding (and is credited with the discovery of Pokémon eggs). Elm is a known scatterbrain who, when working, forgets to eat. He often gets so focused on his studies that he becomes completely oblivious to his surroundings.
Professor Birch in Pokémon
Professor Birch is the stoutly Pokémon professor for the Hoenn Region. He is more outgoing than the other professors and often takes his research with him outdoors, hence those really cool sandals. Birch’s research specialisation is Pokémon behaviour in the wild.
Giovanni from Pokémon
As the head of Team Rocket and the former gym leader for the Viridian City gym in the Kanto Region, Giovanni chooses Persian as his Pokémon. He normally has a very calm demeanour, trusting Jessie and James despite their nearly uncountable number of failures, but he is really a ruthless and evil leader. Let’s just say his fashion style is… unique.
Professor Oak in Pokémon
Are you a boy? Or are you a girl? Professor Oak is the very first Pokémon Professor you meet in the wonderful world of Pokémon. He’s forgetful, unable to remember the name of his nephew in games and he’s always around to remind you that you can’t use a bike in the ocean. However, he is an indispensable companion to Ash (and, really, all trainers).
The Eevee Brothers
In the Pokémon: Indigo League episode, “The Battling Eevee Brothers,” Ash (Veronica Taylor / Rica Matsumoto) and his friends come upon four brothers trying to convince the youngest how he should evolve his beloved Eevee. Each of the elder brothers has one of the original Eeveelutions: Jolteon, Flareon, and Vaporeon. Their hair and pants reflect which Pokémon specific element/type their Pokémon is now affiliated with.
Gym Leader Whitney
A gym leader who trains only the cutest of Normal-type Pokemon, Whitney (Yuko Miyamura / Megan Hollingshead) is a rather unorthodox trainer. She’s young, sensitive, and admittedly a bit immature, but her Miltank is a force to be reckoned with. If you defeat her, she will give you the Plain Badge…but only after crying about it.
