Koda Duck has been following Kasumi for over 200 episodes, though there are a few episodes where Koda Duck plays a very important role.

TV32 The Ninja Duel at the Asahi Dojo A fun episode where Kodama Duck first flexes his muscles in front of Kasumi

TV91 Goodbye Kodama Duck, Here Comes Kodama Duck A very famous episode, but I'm afraid the most famous Pokémon episode is the one with the most controversy, 3D Dragons. Incidentally, the highest rated Pokémon episode was TV18, "Seppuku's Vacation", which also featured Granny Gold and Granny Silver.

TV218 "Kotoshi Versus Kasumi, The Final Battle of the Maelstrom Legends Tournament! Sorry for Chi, but still rooting for Koda Duck.

AG139 "Melancholy Koda Duck!!!
