May is a Pokemon coordinator from the Hoenn region who also spent a significant amount of time as one of Ash Ketchum's traveling companions.
May is also the older sister of Max and daughter or Norman; the Petalburg City Gym Leader.
May is a very kind and sweet person but can show a tougher side of her such as when she argues with her brother Max.
After the Johto League Silver Conference, Misty went back home to Cerulean City to become the Gym Leader. Ash was left without a female traveling companion, but soon after he arrived in the Hoenn region he meet May and along with Brock and Max formed a new traveling team.
In the English dub version of the Pokemon anime series by 4Kids Entertainment, May was originally voiced by Veronica Taylor who also voiced Ash Ketchum.
When 4Kids lost the license for Pokemon, the anime was then produced by Pokemon USA. Pokemon USA didn't hire the 4Kids voice actors, and after an audition for the Pokemon 10th anniversary special; The Mastermind of Mirage Pokemon May was voiced in all future appearances by Michele Knotz.
