Bianca's Minccino is a Pokémon owned by Bianca, and the first one she caught.
Minccino was first seen in Minccino, Neat and Tidy where he had stolen the badge case that Bianca was supposed to deliver for Ash. After seeing how cute the Pokémon was, Bianca had been determined to catch Minccino; however, she was much stronger than expected as she relied on various techniques by using her attacks (his Tickle helped win quite a few battles, and Attract took care of Ash's Snivy). Throughout the episode, Minccino was shown to be a clean freak as she has an obsession for cleaning things with her broom like tail. She almost escaped due to Bianca's clumsiness; however, it was due to her dusty Poké Ball which led to her accidental capture (due to Minccino's craze for cleaning things as well as the fact that she was already weakened from the battle with Ash's Pikachu).
It battles another Zebstrika in Enter Elesa, Electrifying Gym Leader!, this time under the ownership of Elesa. His DoubleSlap and Swift attacks are evaded, and he is struck with Flame Charge. Unlike Shelmet before him, he had better endurance and actually landed a hit with Hyper Voice, which does major damage. He endures another Flame Charge, but falls to a supereffective Double Kick.
In Crisis at Chargestone Cave!, Minccino is used to lure away some giant wild Galvantua from Ash's Pikachu by using his new Thunderbolt. However, the two were captured by the Bug types, and were asked to power up the weak wild Joltik in the area with their Thunderbolts. They did so, and when Ash and Bianca found them, they believe that they are being forced to do that. After they got away from the EleSpider Pokémon, he teamed up with Pikachu in battling James' Yamask, where it was hit by Night Shade, but he and Pikachu fought back and launched their own attacks. They won the battle after Cilan's Dwebble evolved while battling Jessie's Woobat.
