In the core series

★ Starfall Street ★

Cassiopeia first interacts with the player in the school's cafeteria through their Rotom Phone, having hacked it in order to reach them. They recruit the player into their mission, Operation Starfall, which is to bring down Team Star by defeating its five squad bosses, scattered around Paldea in their respective bases, and their "big boss" who founded the team.

When the player is close to a base, Cassiopeia will call and brief them on the base and its squad boss. Once the player has defeated the squad boss, Cassiopeia will call again and reward the player with League Points and an increased variety of TMs in the TM Machine. Cassiopeia also summons Penny of Operation Starfall's supply unit to give the player a bonus reward, which is a lot of Pokémon materials. Clive gives the player their bonus reward instead of Penny after the player has defeated their fifth base.

The player is rewarded with increasing quantities of LP after defeating each squad boss for the first time.

  • 5,000 for defeating one squad boss.
  • 6,000 for defeating two squad bosses.
  • 7,000 for defeating three squad bosses.
  • 10,000 for defeating four squad bosses.
  • 20,000 for defeating five squad bosses.

After defeating all the squad bosses, Cassiopeia reveals that they were the "big boss" and tells the player to meet them at the schoolyard of Naranja AcademyS/Uva AcademyV after dark, where their true identity is revealed.
