Moltres and the two other legendary Flying Pokémon are the basis for the second movie. Moltres is one of the Legendary Pokémon that is being captured together with Articuno and Zapdos. When they are all brought together, an extremely dangerous fight breaks out among the three. However during the duel the Lugia comes out and tries with Ash Ketchum to bring peace between the three.
Moltres is one of the two legendary Pokémon that is found in the Victory Road of the generation it was introduced in, the other Pokémon being Terrakion.
Out of all legendary Pokémon found in the Pokémon games, Moltres's location has been moved the most.
Before Generation III, Moltres was shown to have wings fully engulfed in flames.
It is uninformed that this is purposely made but the last syllable of each of the Legendary Birds is a number in Spanish (ex. Articuno, Zapdos, Moltres). Meaning "Artic-one", "Zap-two" and "Mol-three" respectively. Because of the pun, Moltres would be the third Legendary Bird. Also, Moltres' name could be hinting at the other two main fire type legendaries in the Pokémon games: Ho-Oh and Reshiram. because its name is Moltres, tres being Spanish for three, and Mol being the first syllable of Molten, Moltres could have been foreshadowing the appearances of Ho-Oh in Generation II, and Reshiram in Generation V.
