May ('ハルカ Haruka) is a young energetic Pokémon Coordinator currently travelling through various regions and competing in Pokémon Contests. She started her journey travelling through the Hoenn region accompanying Ash and Brock, along with her little brother Max. When Ash and Brock leave for Sinnoh, she goes to Johto alone without Max. She appears in a few episodes of Pokémon Diamond and Pearl: Battle Dimension, where she travelled to Sinnoh to enter the Wallace Cup. She is also shown to have a disputable romantic interest in Drew, as she becomes flustered when accused of liking him, and blushed a considerable amount in de Spontaneous Combusken when Drew complimented her on needing two more ribbons.
She has rivalries from some contest participants, Drew, Harley, and Jessie of Team Rocket, and goes on to win many contests. She is in four Pokémon movies. She picked Torchic as her first Pokémon and Squirtle as her first KantoPokémon. May is generally a very sweet, fun-loving, caring, kind-hearted, and a brave person. But sometimes a real go-getter type of confident person. When it comes to certain things, she can be a glass half-full type of a straight woman that she is, even though she is a very nice person.
But she can have a tougher side sometimes, such as when she argues with her brother, Max. Despite that they argue once in a while, she has definitely shown that she really deeply cares for her brother. She helps people a lot, especially ones with romance problems. May has a tendency to rely on luck once in a while when it comes to certain things.
She really loves cute Pokémon and flashy techniques, and competing in contests. She really loves making her own Pokéblock with recipes that she thinks up, including ones she calls "May's Purple Surprise" and "May's Pink Surprise" while everyone else rejected them after tasting them, the only ones who liked her Purple Surprise are her Munchlax and Jessie.
When May saw a contest battle for the first time, she decided to become a coordinator. She then had to overcome her fear of bug type Pokémon by raising her Wurmple into a Beautifly.
While Ash and Brock chose to travel to Sinnoh, May decides to follow her rivals to Johto. However, she meets up with Ash, Brock, and Dawn in Sinnoh, wearing a green bandanna like the character Pokémon Emerald, then sometime later participates in the Wallace Cup. Dawn once referred to her as "Princess" which makes the fact that she has an unknown identification believable.
After narrowly losing to Dawn in the Wallace Cup Finals, she leaves the group to continue her journey in Johto. This was May's last appearance, and the future of her appearing again remains uncertain.
May has a unique taste for food. She loves to taste many different types of food. As a Coordinator, May was able to learn more about Pokémon, and her knowledge became greater during her journey in both Hoenn and Kanto for her contests that she competes in, that she can come up with different types of attacks.
She was also able use these combinations in battle. For example she would use her Combusken's Fire Spin and her Squirtle's Bubble to create a combination of Fire and Water. Which was dubbed by Lillian's Medichan as a Fire and Water Whirlwind. She was able to knock-out Drew's Flygon and his Absol. During her journey she won numerous ribbons in both Hoenn and Kanto and she is still using those skills and talents in Johto currently. But May did reappear during the Sinnoh saga in four episodes Meeting Ash, Pikachu, Brock, Dawn and Zoey for the Wallace Cup. May also has a personal ending theme song called I Won't Lose also called Haruka's theme in Japan in two episodes of the Pokémon anime's Kanto battle frontier saga the theme was used as background music in Curbing the Crimson Tide! and again in the next episode What I Did For Love!. It was also used during the Sinnoh Wallace Cup saga.
Blaziken was given to May by Professor Birch in Littleroot Town when it was still a Torchic. She chose it as her starter Pokémon because she thought Treecko was creepy and scary (though she later called them cute in Trees a Crowd), while the starter Mudkip had attacked her earlier with a Water Gun to the face. As a Torchic, it evolved in the episode A Shroomish Skirmish, when trying to fend off some Shroomish and Breloom. It later evolved in the midst of a Pokémon battle with Team Rocket.
May watched a Pokémon Contest and she saw a Beautifly and she wanted one. When May caught a Wurmple, Jessie from Team Rocket had one and were switched but were returned to their rightful trainers. Beautifly knows Gust, Aerial Ace, Morning Sun, Silver Wind, and Psychic.
After May left Skitty and Beautifly in Hoenn, she met Ash in Pallet Town and one of Oak's Squirtles seemed to take a liking to her. Professor Oak allowed May to have the Squirtle and travelled in her Poké Ball. He learns powerful moves like Ice Beam, Aqua Tail and Rapid Spin.
May was kidnapped by a Skarmory and ended getting lost in a place called the Forbidden Forest, which is a preserve for Grass-type Pokémon. Then May met a clumsy Bulbasaur trying to pick flowers. It eventually evolved in a Ivysaur and much later it evolved into a Venusaur. She knows moves like Petal Dance, Razor Leaf and Vine Whip.
After May saved the Manaphy egg in Pokémon Ranger and the Temple of the Sea, it hatched and imprinted on May and thought she was its mother. It had such a close bond with May, it began learning words and even learn May's name. But it knew it had to leave and protect Samiya, the Sea Temple, even though it did not want to leave her side. Leaving her behind, it left with a few words including "love" and "you".
