This Quilava is a fire-type Pokémon owned by Clark.
Clark sent Quilava out with his Charizard against Ash Ketchum and his Grovyle and his Glalie. Grovyle and Glalie charged to them for an attack and Charizard used Heat Wave to counter them while Quilava used Flame Wheel. Charizard's Heat Wave successfully hit Grovyle and Quilava hit Glalie. Glalie used Icy Wind on them but both Pokémon weren't affected by it. Clark ordered Charizard to use Steel Wing and Quilava to use Quick Attack. Grovyle successfully dodged the attack but Glalie didn't and took the hit. Grovyle and Glalie charged in for an attack again and Quilava tried to dodge them but failed, taking Grovyle's Leaf Blade and Glalie's Headbutt. Both Charizard and Quilava then used Quick Attack and Heat Wave once more. Heat Wave collided with Glalie's Icy Wind while Grovyle took Quilava's attack. Grovyle then used Pound on Quilava, knocking it out.
