Inside Starfinder Alien Core, you'll find over 200 creatures, including science fantasy favorites like robots, spacefaring fey, and all-new dragons; alien beasts from friendly spiderlike empathnids to fearsome plantlike predator ksariks; and unique monsters that threaten the galaxy of Starfinder, like jinsul troopers and vicious Swarm subspecies. You'll also find legacy Pathfinder creatures with a scifi update, like nanite-infused algollthus, and Starfinder classics like akatas and laser wolves. These creatures cover all levels of play, from scavenging sluglike diathas to powerful Drift-dwelling spectra.

Starfinder Alien Core is the only book GMs need to add enemies and allies of all sorts to their Starfinder Second Edition game, providing enough aliens of all power levels and thematic niches to populate countless worlds. And since Starfinder Second Edition is fully compatible with Pathfinder Second Edition, every alien presented in this massive tome can pull double duty in Pathfinder campaigns with next to no adjustment.
