In Scared Stiff, Zoroark used its Illusion abilities to conceal its territory in Route 20 of Kalos. When Ben stumbled into it, it attacked from the shadows. It scared Ben's Chromastone so it wouldn't shine a light, and used its Illusion ability to take the form of a Trevenant. Ben switched to Fasttrack, which used Foresight to break the Illusion. Zoroark and Fasttrack battle briefly before Fasttrack wins, allowing Ben to capture Toepick in a Dusk Ball. He named it Toepick.
In The Greatest Challenge, Toepick is used in the battle against Corey. It came out of its Pokéball using Illusion to disguise itself as Ben's Crashhopper against Corey's Ishiyama, to deter it from using Fighting moves. It landed a few strikes, before Corey figured out Crashhopper disturbed the water and that the Pokéballs were different. Toepick is hit and revealed. Ben used U-Turn to recall it.
Ben chose Toepick later, no longer disguised. It used its Scary Face to scare and trick Icarus, causing it to crash into a rock. It then uses Night Daze to defeat it. Toepick is then instantly defeated by Bulldozer.
In Negative 10, Toepick disguises itself as Spidermonkey and is chosen to battle Albedo's Mimikyu. Albedo sees through the Illusion instantly and forces them out. Toepick is defeated.
