Neesha used her Blastoise in the battle against Corey and his Gengar in the finals of the Pokémon League. Blastoise used Rapid Spin but Gengar was able to dodge it and used Night Shade. Blastoise wasn't really affected by the attack and froze Gengar with Ice Beam, making Corey recall Gengar. Blastoise withstood Venusaur's Razor Leaf and used Hydro Pump to attack back. It then used Skull Bash to clash with Venusaur's Tackle. Both Pokémon then proceeded to use Hydro Pump and Solar Beam with both attacks colliding with each other, creating an explosion.
