Arachna

The Arachna Spider-Warriors, or simply Arachna, are a sapient species of arachnid-like humanoids from the planet Eternia, closely related to the Andreenids.

Biology
Arachna are blue-skinned humanoids with red eyes, white fangs, and additional spider-legs protruding from their backs, which allow them to cling to vertical surfaces. They can shoot web to immobilize opponents.

History
Arachna are an ancient species and used to be more numerous, but are now extremely rare, with Webstor being described as one of the last members. At one point, they were the dominant civilization on Eternia, but were driven underground by the Snake Men.
