Pokémon League (Alola)/Title Defense

Main article: Pokémon League (Alola)

Unlike in previous games, Pokémon Sun, Moon, Ultra Sun, and Ultra Moon feature the ability for the player to defend their title as Champion upon defeating the Elite Four for the second and subsequent times, instead of battling the former Champion over and over again. Upon sitting on the Champion's throne, the challenger the player faces is selected at random from the following Trainers.

The first Title Defense battle after the initial Champion battle is always against Hau. On subsequent battles, on the first of the month in Pokémon Sun and Moon, Faba always appears; in Pokémon Ultra Sun and Ultra Moon, Lusamine appears instead. Additionally, in Ultra Sun and Ultra Moon, Gladion will only appear starting one month after the player has completed Episode RR. In Sun and Moon, Molayne is a potential challenger, but in Ultra Sun and Ultra Moon, due to him being an Elite Four member, Guzma takes this role instead.
