Bill (Japanese: マサキ Masaki) is a Pokémon Researcher, widely regarded as an expert in many fields, who makes many appearances in both the games and the anime. Bill is most commonly found in his lighthouse, which is north of Cerulean City. He is most notable for his first entrance in the Generation I games Pokémon Green, Pokémon Red, Blue, and Pokémon Yellow Versions, his Pokémon storage system, and his possession of the Evolution Stones. Bill is also a major player in the Evolutions: Destinies game.

In the Games

Generation I

In Pokémon Red, Blue, and Pokémon Yellow, Bill is found at the Cerulean Cape, initially performing an experiment on Pokémon teleportation. He, however, gets combined with the body of a Pokémon and requires the player's help to fix the problem. After things are back in order, he informs you about his Pokémon Storage System and the "Someone's PC" changes to "Bill's PC." He also gives you the S.S. Ticket, allowing you to board the S.S. Anne. Later in the game, you can visit Bill's family in Fuchsia City.

Generation II

In Pokémon Gold, Silver, and Pokémon Crystal, Bill is visiting his family in Goldenrod City. After he gets the Time Machine up and running in Ecruteak City, players can visit him for an Eevee.

Generation III: Hoenn

While visiting Lanette, players can check one of her computers to find an E-mail from Bill. This is the only time that he is mentioned in the game. However, no such mention is made in the Japanese version (not confirmed with Pokémon Ruby and Sapphire).

Generation III: Kanto

In Pokémon FireRed and LeafGreen, Bill is in the same area as in the original games. However, you meet up with Bill on Cinnabar Island after receiving the volcano badge from Blaine. From there, you go to the Sevii Islands and complete a side story.

Elsewhere

In the Anime

Ash, Misty, and Brock meet Bill at his lighthouse in Mystery at the Lighthouse, who is trapped in a Kabuto costume. After pressing the release button, Bill tells Ash and company about a mysterious Pokémon that he has been hearing the cry of recently.

In the TCG

In the Manga

Bill serves not just as a scientist and inventor, but as part of the Pokémon Association.

His various exploits over the years have included; being turned into a Rattata by his experiments and snatched up by a Fearow; helping Red find and capture a missing Eevee; facing Lorelei in combat with Yellow; fighting alongside Green against Bruno's Hitmonlee; and being attacked by a group of playful Staryu after meeting Crystal.

Bill not only designed the Pokémon Storage system, he also maintains it from his home, and was the one who repaired it after the Mask of Ice's Team Rocket sabotaged it, allowing trainers from all over to send their Pokémon to aid Red, Green, Blue, Yellow, Gold, Silver and Crystal in their battle against Ho-oh and Lugia. He also created a portable Pokémon Transfer system using a PokéGear and a Pokédex, allowing Crystal to send Professor Oak the Pokémon she captured while the system was down.

At the end of Volume 15, he is shown working with Daisy Oak, and they seem to be getting along well, hinting at a possible relationship between the two, although there was never any solid evidence provided later.
