Saturn's Octillery was used to attack Rad Rickshaw. It also pulled Pearl into Lake Valor, and used Octazooka to attack his Pokémon. To ensure Pearl does not interfere with his plans involving Azelf, Saturn had Octillery use Gunk Shot on him and Chimler.
Octillery was with Saturn, who reported an intruder in Veilstone City. Cyrus ignored that, and asked of his commanders to go to Spear Pillar at Mt. Coronet. There, the three commanders awaited his coming. As Cyrus went to conduct the final phase of the plan, Saturn got attacked by falling rocks, so he and Octillery evaded that attack. In fact, Roark, Gardenia and Fantina arrived to stop them. Octillery fired an attack at the Gym Leaders, but the attack was deflected by Crasher Wake's Pokémon. Since more Gym Leaders started to gather, Saturn faced Roark and Fantina. He sent Croagunk, Abra and Octillery against the duo's Pokémon. However, the Gym Leaders defeated Saturn and Octillery.
