Gwenpool is one of the playable in-game characters in LEGO Dimensions 2: The Rise of Enoch, from the Marvel Comics franchise.
Gwendolyn Poole is a Marvel Comics fan from the "real world" who somehow entered the Marvel Universe. Unwilling to be an extra, she went to a tailor for superheroes in order to stand out. When the tailor misread her name as "Gwenpool," she was given a pink and white Deadpool-esque costume and eventually kept the misreading as an alias. Gwenpool possesses no powers or abilities of her own. However, because of her knowledge of comics, she is fully aware of almost everything about everyone in the Marvel Universe, including their secret identities. She tends to use her comic book knowledge to her advantage, such as using plot armor to survive ordinarily lethal feats. Much like Deadpool, she has little care or remorse toward her actions, since she doesn't believe anything in the Marvel Universe is real.
