Clarissa's Zapdos

Clarissa's Zapdos is a Pokémon she obtained in Kanto as a Legendary Guardian.

As a Wild Pokémon
Clarissa caught Zapdos during her time between Johto and Hoenn after her Jolteon was attacked by it. This prompted her to investigate what happened in the Power Plant with Jolteon, Charizard, Gengar, Arcanine, Ampharos, and Houndoom. Zapdos managed to defeated all of her Pokémon but Jolteon, who absorbed all the electric attacks with Volt Absorb. The Eeveelution managed to wear down Zapdos enough for Clarissa to catch.

Sparks: Side Stories
Directly after capturing Zapdos he attempted to flee his new trainer but to no avail. Clarissa then calmed it down and explained why she caught him. Zapdos seemed to understand and accepted his new trainer. After than she left Zapdos and Jolteon in the Power Plant to help out the workers.
