The Renegade Pokémon, Giratina, has officially returned to Pokémon GO Raid Battles, but it’s no longer in its Altered Forme. This Ghost- and Dragon-type Legendary Pokémon, originally discovered in the Sinnoh region, has emerged from the Distortion World and is now appearing in its Origin Forme as a level 5 Raid Boss until April 29 at 1 p.m. PST. You’ll only be able to use the Premier Balls you earn from defeating Giratina to catch it, so it’s crucial to be prepared.
