Master Hamm (Japanese: ハマグリ Hamaguri) is a character of the day who appeared in Pasta La Vista. He is the owner of the Fighting Dojo in Saffron City.
He tried to convince his son Kyle Hamm to run the dojo since he claimed that he was too old to do it, and Kyle refused to do so. So they challenged each other to a match. If Kyle won, he would be free to do whatever he wants, including his wish to run his own 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.
