The Pokémon anime has given us some of the most memorable characters in cartoon history, from brave trainers to hilarious villains. Whether you grew up watching Ash chase his dream of becoming a Pokémon Master or laughed at Team Rocket’s endless failures, these characters have a special place in our hearts.
Ranking them is no easy task, but these 15 stand out as the very best the series has ever offered.
1. Ash Ketchum
Few characters in anime history have inspired as many kids to chase their dreams as Ash Ketchum. Starting as an eager rookie from Pallet Town, he spent 25 seasons working toward one goal: becoming the world’s greatest Pokémon trainer.
He finally earned that title, proving that heart and hard work always win out. His journey touched millions of fans worldwide, making him one of the most iconic cartoon heroes ever created.
2. Pikachu
No other Pokémon has captured the world’s heart quite like Pikachu. From the very first episode, this little yellow mouse showed more personality than most human characters, making audiences fall in love almost instantly.
Pikachu’s bond with Ash grew stronger with every battle and every emotional moment shared between them. More than just a mascot, Pikachu became a symbol of loyalty and friendship that defines the entire franchise.
3. Misty
Before anyone else joined Ash on his journey, Misty was already there, bicycle grudge and all. Her fiery personality and deep passion for Water-type Pokémon made her one of the most exciting companions the show ever introduced.
She could be tough and stubborn, but her caring side always shone through when it mattered most. Fans still consider her Ash’s most iconic travel partner, and her return episodes are always met with pure excitement.
4. Brock
Brock is the kind of friend everyone wishes they had on an adventure. As a former Gym Leader turned caring companion, he cooked meals, gave advice, and kept the group grounded through every wild situation they faced.
His loyalty to Ash never wavered across multiple series, earning him the title of the most dependable companion in the show. Later becoming a respected Pokémon doctor only added more depth to an already lovable character.
5. Team Rocket Trio – Jessie, James, and Meowth
Blast off at the speed of light! Jessie, James, and Meowth have been chasing Ash and Pikachu since day one, and somehow, fans love them more for it.
Their dramatic blasting-off scenes became one of the most quoted running jokes in cartoon history.
What makes them truly special is the warmth underneath their bumbling villainy. Their chemistry, humor, and surprising moments of kindness turned them into fan favorites who appeared in every single series of the anime.
6. Gary Oak
Gary Oak walked into the Pokémon anime like he already owned the place, and honestly, his confidence was kind of earned. As Ash’s childhood rival, Gary pushed our hero harder than almost anyone else in the series.
What made Gary’s arc so satisfying was his growth from arrogant rival to genuine researcher and friend. His early attitude made fans dislike him, but his evolution into a mature, respected character made them respect him deeply by the end.
7. Serena
Serena did something no other companion had done before: she gave Ash his very first kiss. That moment alone secured her legendary status among fans, but her character was so much more than that single scene.
Her journey of self-discovery, finding her passion for Pokémon Showcases, resonated with viewers who were also figuring out who they wanted to be. Serena remains one of the most emotionally rich companions the anime has ever written.
8. Dawn
Dawn brought a fresh energy to the Pokémon anime when she debuted in the Diamond and Pearl series, and fans immediately connected with her bubbly, determined spirit. Her rivalry and friendship with Ash felt natural and fun to watch.
Her catchphrase, “No need to worry,” became iconic partly because she had plenty of reasons to worry but pushed forward anyway. Dawn’s Contest journey showed younger viewers that chasing a creative dream is just as valid as battling for badges.
9. Paul
Paul is widely regarded as the greatest rival Ash ever faced, and for good reason. His cold, results-only approach to training was the direct opposite of everything Ash believed in, creating a rivalry full of real tension and meaning.
Unlike many rivals who came from the video games, Paul was created specifically for the anime, making him feel fresh and original. Their battles were some of the most emotionally charged in the entire series, especially their climactic showdown at the Lily of the Valley Conference.
10. Cynthia
Cynthia walks into every scene like the final boss of the entire Pokémon world, and that feeling never goes away. As the Sinnoh Champion, she commands respect from trainers and fans alike with her calm, elegant battle style.
Her Garchomp alone has caused more anime heartbreaks than almost any other Pokémon in the series. Despite fewer appearances compared to other major characters, Cynthia holds a legendary reputation that keeps growing stronger with every fan ranking and discussion.
11. May
May started her Pokémon journey not even wanting to become a trainer, which made her growth into a passionate Pokémon Coordinator all the more rewarding to watch. She discovered her love for Contests organically, and viewers felt every step of that discovery.
Her sibling dynamic with Max added humor and heart to the Advanced Generation series. May proved that a character finding their own path, rather than following someone else’s, can be just as compelling as any gym battle storyline.
12. Professor Kukui
Professor Kukui brought something genuinely new to the Pokémon anime: a mentor figure who felt like family. His warm, enthusiastic personality made the Alola series feel like a summer vacation that no one wanted to end.
His secret identity as the Royal Mask, a wrestling-style Pokémon battler, added a fun, playful layer to his character that fans absolutely loved. Acting as Ash’s surrogate father during the Sun and Moon series gave the show an emotional warmth that still stands out today.
13. Iris
Iris had one of the boldest character arcs in the anime, going from a free-spirited Dragon-type enthusiast to eventually becoming the World Coronation Series Champion. That achievement alone puts her among the elite trainers the show has ever featured.
Her habit of calling Ash a little kid was both funny and oddly charming. Iris always had a fierce independence that made her stand apart from other companions, and her return as Champion was one of the most satisfying payoffs in recent Pokémon history.
14. Jigglypuff
No Pokémon in the entire anime caused more accidental chaos than Jigglypuff. This tiny pink singer would perform its lullaby with such passion, only to find every single audience member fast asleep by the end of the song.
The marker drawings on sleeping faces became one of the show’s most beloved running gags. Jigglypuff’s mix of adorable design and hilariously bruised ego made it a fan favorite that appeared across multiple regions, always stealing the scene without even trying.
15. Tobias
Tobias showed up to the Sinnoh League with almost no backstory and somehow managed to own both a Darkrai and a Latios, two of the most powerful Legendary Pokémon in existence. The sheer audacity of that lineup left fans speechless.
He defeated Ash’s team using only those two Pokémon, which sparked debates in the fandom that continue to this day. Tobias remains one of the most mysteriously powerful characters the anime has ever introduced, and his brief appearance left a permanent mark on the series.
