>>103799689marvel wasnt trying to create their own harley. They already have deadpool, who's the character DC is trying to ape in all of Harley's books and minis.
Gwenpool was marvel's attempt at trying to cash in on the Gwen Stacy + superhero craze variant since it was the most popular one and spider-gwen was fairly successful.
They had no idea they would end up creating a decent story out of it. A story where gwen isn't even Gwen Stacy with Deadpool powers but just random girl who got trapped in 616.
It was unintentional and really not needed.
