WATCH: Pokemon’s meanest villains join forces in new ‘Ultra Sun’ and ‘Moon’ trailer

The trailer for the upcoming Pokémon “Ultra Sun” and “Ultra Moon” is out, and it looks like it’s going to be one grand nostalgic reunion.

In any good game, villains, of course, are as integral as the main characters, and the Pokémon Company is bringing back its most notable “bad guys” for the latest installment.

According to Game Spot,  the game still takes place in the tropical Alola region like its predecessor, where players would still have to battle the nefarious Team Skull throughout their journey.

However, players will also have to weather the storm brought out by iconic villains from previous titles—particularly Giovanni, the original boss of Team Rocket; Team Aqua and Team Magma’s Archie and Maxie; Team Galactic’s Cyrus; Team Plasma’s Ghetsis; and Team Flare’s Lysandre.

Aside from the classic antagonists, the sequel will feature a wide range of legendaries—which will be exclusive to a specific version.

The “Ultra Sun” version will feature “Ho-oh,” “Raikou,” “Groudon,” “Latios,” “Dialga,” “Heatran,” “Reshiram,” “Tornadus” and “Xerneas.”

“Ultra Moon” will have “Lugia,” “Entei,” “Kyogre,”  “Latias,”  “Palkia,” “Regigigas,”  “Zekrom,” “Thundurus” and “Yveltal.”

The game’s original legendary Pokémon, Solgaleo, Lunala and Necrozma will be available as well, the report said.

Furthermore, a cool new addition called “Battle Agency” will allow players to rent some of these extra-strong, rare Pokémon and do battle.

“The Pokémon you can rent for these battles will increase as you mingle with other players around you or over the internet,” an excerpt from the Pokemon website reads.

Pokémon “Ultra Sun” and “Ultra Moon” are out on Nov. 17 exclusively for Nintendo 3DS.  Khristian Ibarrola /ra
