Yes, Spider-Gwen, also known as Gwen Stacy, is a fictional character from Marvel Comics who exists in a parallel universe known as Earth-65. In this alternate reality, Gwen Stacy, traditionally known as Peter Parker's girlfriend in the main Marvel Universe (Earth-616), becomes the superhero Spider-Woman or Spider-Gwen.
Earth-65 features several significant differences from the main Marvel Universe. In this reality, Gwen Stacy gains spider-like powers instead of Peter Parker, and she becomes the web-slinging hero known as Spider-Woman or Spider-Gwen. The character first appeared in the comic book series "Edge of Spider-Verse" in 2014 and gained popularity, leading to her own ongoing series titled "Spider-Gwen."
In the Marvel multiverse, numerous parallel universes exist, each with its own variations and iterations of characters. Spider-Gwen's Earth-65 is just one example of these alternate realities. The concept of parallel universes allows for creative storytelling opportunities and allows characters like Spider-Gwen to explore unique narratives and perspectives while still being connected to the larger Marvel multiverse.
