Cent first appeared in PASM01, where he was used to battle a pair of Team Skull Grunts that had attacked Moon. He faced the Grunts' Salandit and easily defeated them with Pay Day. Later that day, Sun and Moon were attacked by Tapu Koko. Sun sent out Cent and Dollar to battle Tapu Koko, but the two immediately began fighting each other instead. Though the attacks seemingly did nothing, Tapu Koko fled, leaving behind a Sparkling Stone in the process.
In PASM06, Cent was used to battle Guzma in the second round of an Iki Town festival tournament. After Dollar was defeated by Guzma's Masquerain, Cent was sent out to replace it. Cent won by covering Masquerain's wings with water from its own Water Sport, leaving it unable to fly and vulnerable to be hit by Night Slash. Afterward, Guzma switched in his Golisopod, which proceeded to attack Cent relentlessly. When Golisopod's trash-covered claws dirtied the coin on Cent's head, it flew into a rage and furiously defeated Golisopod, allowing Sun to move to the next round.
In PASM07, Cent was used to battle Gladion in the final round of the tournament. It went up against Gladion's Type: Null, but was easily defeated, forcing Sun to switch it out for Dollar.
In PASM08, upon arriving on Akala Island, Sun met Lana, Kiawe, and Mallow, the Trial Captains of Akala. Unsure if he was worthy of taking the Island Challenge, Kiawe challenged Sun to a battle. Sun agreed and used Cent to battle Kiawe's Marowak. Cent was initially bewildered by Marowak's ability to manipulate its flames, but managed to land a hit after Sun told Cent to ignore the flames. The battle was called off after Kiawe decided to call his boss at the Thrifty Megamart and apologize for leaving work without telling anyone.
In PASM10, Cent was used in Sun's first trial, which was to fight against the Totem Pokémon of Brooklet Hill, a School Form Wishiwashi. Due to its immense size and strength, the Totem Wishiwashi was a tough opponent. Cent managed to defeat it after Sun instructed it to hit Baht, the main Wishiwashi located in the left eye. After dodging its attacks, Cent closed in on Baht's location and attacked it. The attack forced the Totem to separate back into its component Solo Form Wishiwashi, giving Sun the victory.
