Character
Mr. Stone is often referred to as "Mr. President" by his employees, however he isn't one for formalities. He prioritizes quality products, and is prepared to invest in experimental technology rather than profit. The President also makes a point to know all of his employees, namely for security purposes.

He often escapes his business duties, much to Kennedy's dislike, to walk the streets of Rustboro City in the search for new inventions. He often speaks with children, finding their young and inquisitive minds to be among the biggest source of inspiration.
