He is a wandering minstrel who enjoys music and as such carries his golden harp with him always, which is shaped like a Mew. During battles, he is calm, and prefers to give commands without shouting, although his commands are more like asking politely.

He 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 a Pokémon Coordinator and didn't know what path to take. 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 a Pokémon Trainer as well as a Coordinator.

He later appears again in A Secret Sphere of Influence!, where he is falsely accused and arrested due to Jessie, James, and Meowth's stealing of the Adamant Orb.

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 with Kenny in Marian's news report about coordinators.

According to The Greatest - Everyday!, Nando will compete in both the Sinnoh Grand Festival and the Sinnoh League Conference.
