Evolve Shelgon during or up to one hour after Pokémon GO Community Day to obtain Salamence that knows the exclusive move Outrage

This month’s Pokémon GO Community Day will occur on Saturday, April 13, 2019, from 3 p.m. to 6 p.m. in your local time zone in various territories across the globe, including the Asia-Pacific region, Europe, the Middle East, Africa, India, the Americas and Greenland. Participants will have the opportunity to catch plenty of Bagon during the three-hour span, and if you evolve Shelgon (the evolved form of Bagon) into Salamence during the event or up to one hour after the event, your Salamence will know the special move Outrage, which it is normally unable to learn. This move will be available only to Salamence evolved during Community Day. Additionally, Lures will last for three hours and Trainers will earn three times the normal XP for catching Pokémon during the hours of the event. Shiny Bagon, Shiny Shelgon and Shiny Salamence will also make their Pokémon GO debuts on April 13.
