Tupp is the main lead of a trio of Team Skull Grunts that harass people around Hau'oli City and the rest of Melemele Island. His main partner Pokémon is Yungoos. Tupp's design is based off the Male Team Skull Grunts from the main series games.

In Tupp's youth, a bunch of girls thought it was cool that Tupp already had a partner Pokémon but when they saw Ilima's Eevee, they thought it was a lot more cute than his Alolan Grimer. Since that day, Tupp has had a grudge against Ilima because he blames him for stealing the glory days of his youth. Dude's like Tupp have a hard time with girls because they have to compete against popular guys like Ilima and they don't stand a chance.
