Mai
Mai appeared in DP168. She was spotted unconscious floating down a river in a boat by Brock. He called out to her trying to warn her of an on coming waterfall. But she did not respond. He jumped in the river to stop the boat then used Happiny to pull them out of the water. Afterwards, Mai finally wakes up and introduces herself.
Because Brock saved her, Mai asks him to escort her to a flower field. Ash and friends eventually discovered that Mai was harboring an injured Shaymin. She explains that she was approached by Shaymin because it was being attacked by a trio of thugs who wanted to take Shaymin.
Mai eventually gets to the flower field that has Gracideas and Shaymin is about to transform in to its Sky Forme. There it defeats Team Rocket and is reunited with its friends. Mai then bids Shaymin farewell.
