Tower Tycoon Palmer first mentioned Volkner in Challenging a Towering Figure!, stating that after witnessing his battling prowess, Ash would be able to give Volkner "a shock."
Volkner made his first personal appearance in DP165. The episode revealed that he had met Flint in their youth, becoming rivals and eventually good friends. After becoming a Gym Leader, Volkner designed the walkways of Sunyshore City and other technological improvements for the area. He also designed the Sunyshore Tower, which supplies electricity to the city.
However, he soon grew bored with battling and began handing out free badges to Trainers. After watching Ash's battle with Flint, he regained his interest in battling and decided to accept Ash's challenge for a Gym battle.
