Disney villains, in general, serve as this for the entire franchise, even if the movies are mostly self-contained. You'll see them grouped together as bad guys almost as often as you'll see the princesses grouped together.
Star Wars: Obi-WanKenobi has a pretty consistent and personal series of foes throughout the franchise's various (post-Disney) media, most notably in the movies and the show Star Wars: The Clone Wars. The core ones include General Grievous,note An INCREDIBLY strongand tough cyborg warrior, skilled lightsaber duelist, experienced tactician, and de facto generalissimo of the entire Confederacy's armies and fleetsDarth Maul,note A warrior from Dathomir and Sith Lord with the standard Psychic Powers and lightsaber skills of Force users, to very great extents; started out as a subordinate of Palpatine's Confederacy, but eventually founded his own independent criminal syndicate, Death Watch.Savage Oppress,note A Dathomiri subordinate of Maul; nearly as powerful as him in the Force, in possession of massive superhuman strength and toughness, and loyal, but not too bright.Cad Bane,note Ruthless, murderous, and highly skilled gunslinging bounty hunter who Obi-Wan keeps getting the way of.Hondo Ohnaka,note A notorious space pirate in charge of a large and well-equipped raider gang who comes into conflict with both Obi-Wan's Republic and the Confederacy over his career, often liberally switching sides.Asajj Ventress,note Similar to Maul, but is also a Fallen Jedi who eventually abandons the Sith to become a bounty hunter and anti-hero and Darth Vader.note Needs no introduction.
Austin Powers both uses and subverts the trope: Most of the villains in the piece are already part of a single organization, and most of them are killed off by the Big Bad, Dr. Evil, at the beginning of the movie. However, a few new ones are introduced throughout the series, and since they aren't killed, they comprise a sort of Rogues Gallery—until most of them turn good, leaving only one as truly evil and the other imprisoned.
And that’s not even getting into the enormous amount of comics, books, video games and other media to wear the Big G’s name which include original monsters, with the Marvel Comics giving him Doctor Demonicus, Batragon, Ghilaron, Centipor and Lepirax, the Megans and their Mega Monsters, Red Ronin (though he eventually becomes Godzilla’s ally) and even Marvel superheroes such as the Avengers and the Fantastic Four, Godzilla: Rulers of Earth giving him the Trilopods, the Dark Horse comics giving him Kamerus, Bagorah and the Dianii, the Pipeworks Atari games giving him the Vortaak, Obsidius and Krystalak, and all of those examples are just scratching the surface (and don’t even count some of the one-off monsters!).
