Dollar first appeared in PASM01, battling against a group of Team Skull Grunt's Salandit. He easily blocked all of their attacks and finished them off with Pay Day. Later that day Sun ran into Tapu Koko, who began attacking the group. Sun sent Dollar and En out to fight and the two immediately begin fighting each other. They soon figured out they needed to focus on their opponent and En attacked with Ember while Dollar used Pay Day. While it seemed like their attacks did nothing Tapu Koko ended up fleeing.
In PASM06, Dollar is used to battle Guzma's Masquerain at the Iki Town festival tournament. Using the Water Sport that Masquerain previously used, Dollar begins splashing the Eyeball Pokémon. The water causes Masquerain's antennae to get wet and it begins to lose altitude. Dollar then swiftly defeats it with Night Slash. He next battles Golisopod who hits Dollar with First Impression and proceeds to beat the Scratch Cat Pokémon up. The battle seems over, but Dollar gets back up enraged that the coin on his head got dirty. He attacks furiously with his claws and defeats it with Pay Day, winning Sun the battle. In the finals Dollar faces off against Gladion's Type: Null. Dollar attacks with a Night Slash that easily gets blocked by Type: Null's helmet and is then immediately defeated by X-Scissor.
Upon arriving on Akala Island Sun meets Lana, Kiawe, and Mallow, the Trial Captains of Akala. Unsure if he is worthy of taking the Island Challenge Kiawe sends out his Alolan Marowak to battle Sun while Sun chooses Dollar. Marowak attacks with Flame Wheel and the flame begins chasing Dollar, leaving him wide open to Shadow Bone. Deciding to ignore the flames to focus on the bone Dollar counters with Feint Attack. The battle is then called off as Kiawe makes a phone call, but Sun and Kiawe agree that Dollar would have won after using Assurance.
In PASM10, Dollar is later used in Sun's fight against the Totem Pokémon Lana trained, a horde of Wishiwashi. Although Sun was concerned with not hurting Baht and his group of friends Dollar rushed in and attacked after his coin got wet. Dollar easily gets beat up by the School Form Wishiwashi and Sun decides to focus his attacks on Baht, who is located in the center of the left eye. Dollar manages to get close enough to slash the eye and the Wishiwashi separate, winning Sun the trial.
