Mr. Stone (Japanese: President Tsuwabuki) is the president of Devon Corporation and father of Steven Stone.
Mr. Stone appeared in one episode of the Pokemon anime. His English voice actor is Ted Lewis and his Japanese voice actor is Masahiko Tanaka.
Stone appeared in Stairway to Devon. He helped out Max after he accidentally spilled soda on the PokeNav. While wandering through Rustboro City, he bumped into Mr. Stone, who was showing off some toys he had made to the local children. The man introduced himself as Mr. Stone, an employee of Devon Corporation - the company that makes PokeNavs. Mr. Stone had to return to Devon Corporation due to an emergency, but he invited Max to visit later.
Max found the gigantic Devon building, and asked to see Mr. Stone. Unfortunately, the receptionist said he was busy. Max tried to think of some way he could see Mr. Stone to get the PokeNav fixed.
Mr. Stone was meeting with an Officer Jenny, who wanted to warn him of a villainous team who wanted to steal something from Devon. Mr. Stone then found Max, who had hidden in the building, and had one of the Corporation's technicians repair the PokeNav. Max was surprised to find out that Mr. Stone was actually the president of Devon. Mr. Stone explained some of Devon's products, and Max explained how he had broken his PokeNav. Mr. Stone took Max on a tour of the laboratories, pointing out a project to revive extinct Pokemon from fossils.
Mr. Stone noticed a suspicious scientist and he and Max decided to follow him. Max accidentally alerted the strange man to their presence, causing him to flee. Mr. Stone called security and found out some amber containing prehistoric Pokemon DNA had been stolen.
Ash, May, and Brock had heard of the situation and helped confront the thief on the route. Team Rocket ended up accidentally defeating the thief, and Max was able to recover the amber in the confusion. Officer Jenny explained that the thief was a member of Team Aqua.
Mr. Stone took the children out for dinner, and while eating, he secretly passed Max his repaired PokeNav back.
