While Zapdos is found during Season 5 near a pond, while in the game you can find Zapdos in the Power Plant

Trivia
- Their names consist of the first three Spanish numbers, Articuno, Zapdos, and Moltres. Their National Pokédex numbers go in order from uno to tres, and they are the THREE legendary birds, so it makes logical sense. Before each number, there is a word corresponding to the bird's type.
