Editing May

In ''[[Pokémon Masters EX]]'', May and Mudkip were made available as a playable sync pair that could be recruited at random through the game's Sync Pair Scout feature starting in January 2021. Her Mudkip could evolve into Marshtomp and Swampert through Sync Pair Stories (in which she had to defeat Brendan and Wally, respectively, in one-on-one battle) and her Swampert could Mega Evolve during battle. There was also a spring variant of May in a rabbit-themed outfit with [[Lopunny]] (also capable of Mega Evolving) as her sync partner, which was made available during limited time periods starting in April 2021. In this game, May was depicted as the friendly rival character who was the daughter of Professor Birch and who focused on Pokémon Contests as well as field work, while Brendan was shown as the protagonist. May's spring variant was featured during the "Pasio Eggsplorers" Story Event, where she and Burgh organized an egg hunt on [[Pasio]] and helped to find a Pokémon Egg that had gone missing in the process. During this event, Brendan worried that she was going to give up being a Pokémon Trainer to become a Professor like her father. May ultimately placated his fears, assuring him that while she thought of becoming a Pokémon Professor someday, that would not be far into the future, and she would tell Brendan first before making such a decision. She was also featured in the "Masters of Land and Sea" Story Event, where she helped to keep tabs on Archie and Maxie after their arrivals in Pasio.

*May was a main character in the ''Ruby''/''Sapphire''/''Emerald'' episodes of the Pokémon anime, acting as [[Red#Other Media|Ash Ketchum]]'s new traveling companion following the departure of [[Misty]]. In this version May is the daughter of Norman and has a brother named Max who also travels with them for a time. She initially disliked Pokémon and became a trainer just to travel, but she eventually grew to liking them after traveling with Ash and began competing primarily in Pokémon Contests while Ash took on the gym leader challenge. Her starter Pokémon was a Torchic. After they completed their challenges in Hoenn, they continued in Kanto with May still competing in Pokémon Contests while Ash took on the Battle Frontier. After that series ended, May parted ways to compete in contests at Johto. She also made guest appearances during the Wallace Cup episodes of the ''Diamond & Pearl'' episodes, where she competed in the tournament and lost to [[Dawn]].

*She appears in the ''Pokémon Special'' manga as Sapphire, being featured in the story arcs based on the third generation games. Sapphire was shown as being very tomboyish and dressing in leaves to catch Pokémon, focusing more on her work than appearance and hygiene. After meeting Ruby who was obsessed with beauty, they compete to see if within 80 days Ruby could win all of Hoenn's Pokémon Contests and Sapphire could beat all the gym leaders, with Ruby also giving Sapphire "real" clothes to wear. She made her way through the various gyms, crossing paths with Ruby and battling Team Aqua several times along the way. Eventually she trained under [[Winona]] after losing to her in order to prepare for the fights against Team Aqua and Magma, only to be disappointed when Ruby acts irresponsible. Flashbacks show that Sapphire was inspired to be such a committed trainer by seeing how powerful the prodigy Ruby was as a child. although this same incident made Ruby too afraid to utilize his talents. After Ruby returns and they both train under [[Juan]], Sapphire and Ruby recognize each other from that childhood event, which leads them to confess their feelings to each other. However, after time is altered following the last battles, Sapphire remembers their confessions while Ruby seems to have forgotten. Regardless, Sapphire defeats Norman offscreen to earn her last badge and complete their challenge. In the ''Emerald'' arc she and Ruby arrive at the Battle Frontier to help Emerald capture [[Jirachi]], with Winona advising Sapphire not to give up on Ruby. By the end of the arc all of the Pokédex trainers team up to defeat [[Archie]] and the artificial [[Kyogre]].
