The Legendary Cobalion is returning to Pokemon Go a bit sooner than planned. The Legendary Pokemon was originally scheduled to return for a special Raid Weekend event starting March 20, but that event has since been extended and is now slated to kick off tomorrow, March 17.

Beginning at 1 PM PT / 4 PM ET, Cobalion will once again be featured in five-star Raid Battles. This marks the second time the Legendary Pokemon has appeared in Pokemon Go, but there's a good reason to take part in the event even if you already have one. This time around, Cobalion will know the event move Sacred Sword, and you'll have your first chance to encounter a Shiny Cobalion.
