The Alpha Gang (アクト団 Mission Act) is a group from 2126 AD. Dr. Z, their leader, wants all the dinosaurs so he can build his own Dinosaur Kingdom and rule over it as the Dinosaur King (the same as the English title of the series). They also want the six Element Stones, to summon and control the dinosaurs. They are based at Zeta Point for all but the last few episodes of Series 1 of the anime.
The Alpha Gang are the main antagonists of the original series, based at the artificial island Zeta Point, trying to capture the newest dinosaur of the episode or going after some other object of value. However, they rebuke their evil ways and become good(-ish) in the finale and through the second season (unless no one's looking).
They often use Alpha Droids, overly-obedient robots who are rather clumsy and only as smart as the person controlling them (who, typically, isn't that smart). Dr. Z invented Move Cards and "recreates" several at the beginning of the season for the Alpha Gang's usage. All 4 (6, counting the Deinonychus trio as 3) of the Secret Dinosaurs of season 1 were created, raised, and trained by Dr. Z, and all end up outright hating his guts for the trouble (though Therizinosaurus and maybe Pachycephalosaurus come around by the ends of their episodes).
They own Terry (Tirano) the Tyrannosaurus, Spiny (Spino) the Spinosaurus, and Tank (Saika) the Saichania. Terry was already with them at the start, implying his card remained after the Backlander crashed, along with the Fire and Center Stones; Spiny, Tank, and the Water and Earth Stones were retrieved in rapid succession. Despite defeating numerous others throughout the season, the Alpha Trio was only able to claim five more dinosaurs and several Move Card dinosaurs, but lost them all, typically within 1-3 episodes. Rod, Laura, and Seth later stepped in and successfully caught 3 dinosaurs (Saurophaganax, Stegosaurus, and Ampelosaurus, as well as the enigmatic Velociraptor card) and were able to keep them until the finale arc, when Seth's betrayal forced them to side with the D-Team. In the battle against Seth's Black T-Rex, Rod and Laura summoned several other dinosaurs like Euoplocephalus and Daspletosaurus alongside the D-Team as a small dinosaur army; they then use Megalosaurus and Deinonychus after Jonathan delivers them to Rex.
In Mesozoic Meltdown, the Alpha Gang teams up with the D-Team partly to reclaim the Space Pirates' dinosaurs, but also mostly to get the Cosmos Stones, though their missions typically flounder in the background of the episode. Just like in Season 1, they acquire very few new dinosaurs (into a group collection with the D-Team instead of for themselves), only claiming Edmontonia, but they use Anhanguera (Anhanguera Dive) obtained by the D-Team and reuse Futabasaurus. They also get several new Move Cards from Dr. Z, but only their Ultimate Moves manage to defeat any dinosaurs of the Space Pirates.

Due to the Stones in their possession, they are also able to control any Fire, Water, and Earth Dinosaurs, but the Alpha Controller makes it possible for them to control any dinosaur after they run its card through the machine.
When being sent around the world to find and capture wild dinosaurs, the Alpha Gang uses a variety of homemade vehicles of varying designs, though sometimes they rely on public transport (when they can afford it).
