Unlike some characters in the Marvel universe, Spider-Gwen's costume is not a symbiote. In the comics and film adaptations, the costume of Spider-Gwen, aka Ghost Spider, is a traditionally designed garment, without the living organic properties of symbiotes like Venom. Instead, the costume reflects Gwen Stacy's identity and powers as a superhero. It's important to differentiate Spider-Gwen's costume from the symbiotes to fully understand her character and her history within the Marvel Universe.
