Dollar first appeared in the Sun & Moon chapter, battling against a group of Team Skull Grunt's Salandit. It 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.
Dollar is later 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. It 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 its head got dirty. It attacks furiously with its claws and defeats it with Pay Day, winning Sun the battle.
Typical of its species Dollar is sophisticated, aloof, and unconcerned with how others are doing. It is a competent battler as it is able to parry attacks with ease and quickly finish battles. When out of battle Dollar is very sluggish and lazy. Due to being descended from royalty, Dollar is very prideful and will fly into a rage if the coin on its head is dirtied. Dollar has a strained relationship with En and will attack it whenever given the chance.
