Ahead of their release this month, The Pokemon Company has shared another new trailer for Pokemon Ultra Sun and Ultra Moon. This video shows off more of the new features players will find in the upcoming titles, as well as surprise appearances by some familiar antagonists.

As in the original Sun and Moon versions, players will battle against Team Skull during the course of their journey around Alola, but they won't be the only villainous team in Ultra Sun and Ultra Moon. This time around, players will also have to contend with Team Rainbow Rocket, a villainous supergroup comprised of the leaders from past teams. The group is led by none other than Giovanni, the boss of the original Team Rocket. He's joined by Team Aqua and Team Magma's Archie and Maxie, Team Galactic's Cyrus, Team Plasma's Ghetsis, and Team Flare's Lysandre.
