The latest update for Niantic Labs' Pokémon GO has arrived and with it, the three Team GO Rocket leaders Sierra, Cliff and Arlo have emerged. The new Special Research Task set 'Looming in the Shadows' will have you battle it out in search for Mysterious Components, that can, in turn, be used to create a Rocket Radar capable of finding the trio.
If you manage to beat all three, you will get to fight Team GO Rocket leader Giovanni and net yourself the new legendary shadow Pokémon Articuno to aid you in your quest of catching them all.
Check images of the leader trio as well as the trailer below.
