Julia Carpenter

Within Marvel Comics continuity, Julia Carpenter was recruited by a government group known as The Commission in Denver and 'unknowingly' became a test subject in their experiments. During the experiment she was injected with a mixture described as spider venom and exotic plant extracts, which gave her spider-derived powers similar to those of Spider-Man. Her origin and subsequent history have been told across multiple comic series and alternate continuities.

Sources describe Julia Carpenter through her comic-book visual iconography rather than detailed prose descriptions: she appears in spider-themed costuming associated with the Spider-Woman/Arachne identities and has been depicted in various alternate timelines and media adaptations. In film media she appears (under the name Julia Cornwall/Julia Carpenter) portrayed by Sydney Sweeney in recent cinematic works.

Primary sources state she possesses spider-derived powers described as 'very similar to those of Spider-Man' as a result of The Commission's experiment. Specific power details are not enumerated in the supplied excerpts, but narratives record that her powers were once stolen by the villain Charlotte Witter and were later restored through intervention involving the Shroud and a synthesized duplicate serum. Across storylines she functions as a powered operative, team member, and field agent.
