Should I Purify Moltres?

May wraps up the Giovanni legendary birds quests with Shadow Moltres. Players should not purify their shadow legendaries and keep them as is.

Should I keep Moltres as shadow?

Overall, shadow Moltres is a good choice, but it's nowhere near excellent than other Pokémon that you can pick from your roster. Fire-type Pokémon are some of the weaker choices, especially without the fast attack incinerate in their arsenal, which shadow Moltres does not have, knocking it down a few pegs.

Should you purify legendary Pokemon?

Due to the limited amount of opportunities you have to encounter Giovanni and catch his shadow legendary Pokémon, almost any shadow legendary you capture should never be purified. It's better to keep them in their shadow versions, and the same goes for shadow Ho-Oh.
