Cent first appeared in The Grand Entrance and Delivery Boy Sun, 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 started fighting each other instead. After getting serious, Dollar kept Tapu Koko distracted with Ember, allowing Cent to strike with Pay Day. Though the attacks seemingly did nothing, Tapu Koko fled, leaving behind a Sparkling Stone in the process.
In The Party Crasher and Guzma the Destroyer, 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 Going Ashore and Neighboring Akala Island, 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 Defeat and the Commander of the School of Fish, Cent was used in Sun's first trial, which was to fight against the Totem Pokémon of Brooklet Hill, a School FormWishiwashi. 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 Quarter, the main Wishiwashi located in the left eye. After dodging its attacks, Cent closed in on Quarter's location and attacked it. The attack forced the Totem to separate back into its component Solo Form Wishiwashi, giving Sun the victory.
In PASM19, Cent, along with the rest of Sun's team, helped rescue Moon from an attacking Xurkitree at Po Town. By combining their attacks, they managed to knock Moon from Xurkitree's grasp, though Xurkitree immediately retaliated by smacking them away onto a nearby car.
In PASM20, Cent was used alongside Anabel's Mismagius to battle a Blacephalon that had been summoned to Po Town. Cent slashed at Blacephalon and appeared to decapitate it, only for the Fireworks Pokémon to reveal it is capable of safely detaching its head at will. Cent managed to distract Blacephalon long enough for Mismagius to stun it with Phantom Force, allowing Anabel to try and capture it, only to fail. Blacephalon attempted to counterattack with its Mind Blown, but was blown away by Tapu Bulu's Whirlwind, saving everyone in the process.
While a competent battler, Cent tends to be sluggish and lazy whenever doing anything else. Due to being descended from royalty, Cent is very prideful and will fly into a violent rage if the coin on his head is dirtied. Cent and Dollar have a mutual dislike for one another; if sent out at the same time, they will immediately begin fighting each other instead of the opponent.
