Love me do.
Stephan/Kenyan (Pronounced Stephon in case you got struck by the name gag.) Is yet another rival of Ash. If I recall correctly he was introduced in "Oshawott's Lost Scalchop" where he is revealed to have a Blitzle. We later see him in many tournaments in which Ash participates in. It also known that there is a running gag in the anime involving the mispronunciation of his name. And as far as I know he placed top sixteen in the Pokemon League losing to Ash in the top 16.
His revealed Pokemon were:
Zebstrika, Sawk and Liepard.
Discuss Stephan, the running gag of the mispronunciation of his name and what you think about him here.
