From Bulbapedia, the community-driven Pokémon encyclopedia.
Master Hamm (Japanese: ハマグリ Hamaguri) is the owner of the Fighting Dojo in Saffron City and is the father of Kyle. He was seen in Pasta La Vista.
He was trying to convince Kyle to run the Dojo Gym since he claimed that he was too old to do it, and Kyle refused to do so. So they challenged to a match. If Kyle won, he is free to do whatever he wants, including to run his noodle shop. Since Master Hamm broke his back, Ash took over for him while May took over for Kyle. When they battled, Team Rocket interrupted the match and captured Hitmonlee and Hitmonchan. So Terri, the only student of the dojo, used Hitmontop to battle them. Ash finished them off with Pikachu's Thunderbolt.
Now, Master Hamm understood why Kyle liked making noodles and so decided to travel around making noodles.
