Professor Willow (Japanese: ウィロー博士 Dr. Willow) is a Pokémon Professor who appears in the Pokémon GO mobile game. Similar to Professor Birch, he specializes in Pokémon habitats and distribution. Unlike other Professors who directly give Trainers their first Pokémon, Professor Willow gives Trainers their first Poké Balls to capture their first Pokémon.

Background information

Professor Willow was an only child who learned his love of Pokémon and exploring from his parents. His mother researched Pokémon ecology and his father was fascinated by the outdoors.[4] Before setting out on his own exploration, he worked in a lab studying Pokémon under Professor Oak, whom he still looks up to today.[5]

In addition to Professor Oak in Kanto, Professor Sycamore in Kalos, Professor Magnolia in Galar, and Jacq in Paldea are also colleagues of his.

Despite his confident presentation, Professor Willow confesses to a shy side and values spending time alone outdoors for his research.[6] He always wears his lab coat to help himself focus on his research.[7] His dream is to explore uncharted lands and to examine and document new Pokémon species yet to be discovered in their natural habitat.[8]

Upon discovery of many Meltan-disguised Ditto by his assistants at the conclusion of the Chikorita Community Day, Professor Willow contacted Professor Oak to discuss the matter.[9] It was revealed during later Special Researches that Professor Willow has a Meltan as his Pokémon buddy.

While investigating Team GO Rocket take-overs, Professor Willow recovered some corrupted files from his computer, uncovering data about Team GO Rocket Leaders Cliff, Sierra, and Arlo. He later found out that Team GO Rocket Grunts were dropping Mysterious Components behind them when defeated at invaded PokéStops. With the help of his assistants, the three team leaders, he was able to build an early Rocket Radar prototype to locate the Team GO Rocket Leaders and later the Super Rocket Radar to locate Giovanni himself.[10]

On June 5, 2022, during the second day of the Pokémon GO Fest 2022 event, Professor Willow suddenly disappeared, and in his stead appeared Rhi, of the GO Ultra Recon Squad. It was later revealed that Professor Willow had entered an Ultra Wormhole and ended up in Ultra Space. On August 27, 2022, Rhi and the player managed to rescue Professor Willow from Ultra Space in time for the Pokémon GO Fest 2022 Finale event, though his outfit was changed for a few months.

On November 5, 2022, following the Dratini Community Day Classic event, Professor Willow was contacted by Jacq when Trainers discovered a ?????? Coin from the Paldea region upon spinning a golden PokéStop. Jacq contacted Professor Willow again soon after to discuss the ecology of Gimmighoul. Gimmighoul's Chest Form was named by Jacq, while its Roaming Form was named by Professor Willow.[11]

Transferring Pokémon

The player can transfer Pokémon to Professor Willow using the "Transfer" option on the status screen in exchange for one Candy for that Pokémon's evolutionary family. A Pokémon transferred to the Professor is permanently lost, equivalent to releasing a Pokémon in the core series games.


Candela, Blanche, and Spark

Professor Willow has three assistants who each are head of a team that research Pokémon in different ways. They perform this research inside Gyms owned by their respective teams, with each team's mascot being one of the Legendary birds. The leader of the teams will also appraise the Pokémon of trainers on their teams when asked to.

His assistants are:

  • Spark, the leader of Team Instinct (Japanese: チーム・インスティンクト Team Instinct), who is researching Pokémon breeding. Team Instinct Trainers believe a Pokémon's intuition is linked to how they are hatched. Team Instinct is represented by Zapdos.
  • Blanche, the leader of Team Mystic (Japanese: チーム・ミスティック Team Mystic), who is researching Pokémon Evolution. Team Mystic Trainers believe that by staying calm and analyzing every situation, they can't lose. Team Mystic is represented by Articuno.
  • Candela, the leader of Team Valor (Japanese: チーム・ヴァーラー Team Valor), who is researching Pokémon strength. Team Valor Trainers believe that their Pokémon are the strongest because they train to naturally enhance a Pokémon's power in search of true strength. Team Valor is represented by Moltres.



Appearance from Pokémon GO between August 27th and November 30th, 2022[12]
