Nando made his debut appearance in Dawn Of A New Era!. At the time, he was confused as to whether he should challenge Gyms or become aPokémon Coordinator. Trying to decide between the two, he battled both Ash and Dawn with his Budew, which evolved into Roselia during his battle with Ash. After the battle, Nando decided to become both a Pokémon Trainer and a Coordinator.
Nando also appeared in Dawn's Early Night where he entered the Hearthome Contest, which he won by defeating Zoey.
Nando made a cameo in A Breed Stampede! alongside Kenny in Marian's news report about Coordinators.
After a long absence, he appeared again in Last Call — First Round! as a participant in the Sinnoh Grand Festival. He made it past the Appeal Round and quickly reached the Top 4 as seen in Coming Full-Festival Circle!. In the said episode, he fought a hard battle against Zoey with his Lopunny and Kricketune, even impressing Fantina a lot with their combinations; however, Zoey eventually won the battle. In the same episode, Nando can be seen playing music to the Pokémon around the area. He made a brief appearance in the following episode watching Dawn and Zoey compete in the finals and then again after the Grand Festival had finished announcing that he was going to compete in the Lily of the Valley Conference.
He also appeared in An Old Family Blend!, where it is revealed that he is Ash's first opponent in the Sinnoh League at the Lily of the Valley Conference, with the match occurring in the following episode. Despite his Pokémon putting up a good fight, he lost his match against Ash and was eliminated. After the match, he mentioned that he would continue his travels in order to train further before leaving.
Nando had a cameo appearance in Zoroark: Master of Illusions.
