Mr. Saridakis is a character of the day who appeared in On Olden Pond. He heads the property development company Saridakis Industries.

After a traumatic childhood experience where he almost drowned in a lake while fishing, Mr. Saridakis became determined to buy that lake and build Leisure Land, an amusement park and spa complex, over it. However, Tiffany, who owns a boathouse with her grandmother Galea on the lake's edge at the side, refused to sell their property, so he used his Crawdaunt to scare away all the Pokémon and the people who come there to fish.

Ash challenged Mr. Saridakis to a battle to decide the fate of the lake. Ash used his Corphish, while Mr. Saridakis used Crawdaunt. Team Rocket interfered the battle, however, and stole Crawdaunt. During his attempt to save his Crawdaunt, Mr. Saridakis was knocked into the lake, until he was saved by Galea and a Dragonair, which lives in the lake. He realized that it was Galea and Dragonair that saved him all those years ago, and in gratitude, he decided to cancel his plans.
