The Gengar was hit. Bad. He tried to stand up before falling over, unconscious.
"Good job, Loki," she told him before returning him to his Pokeball. The good news was that she had 5 other Pokemon with her. He got the first KO, but it was nowhere near the end of the battle.
"Don't get too overconfident," she said harshly, taking another Pokeball from her belt and throwing it. A Cloyster now stood in place of Gengar. "You're not the only one who can attack super effectively. Shelly, use Surf!"
