She also shares the similarities of Deadpool due to both being mercenaries and having awareness that their in comic books, with the former having this ability due to living in a universe where Marvel heroes only exist in comic books. She and her brother Teddy were sent to the prime universe by unknown reasons, but Gwen would become a mercenary and due to her extensive knowledge of the Marvel universe, had the advantage against opponents. Gwenpool has vast knowledge of the Marvel Universe from comic books in her universe, such as every secret identity of heroes and villains. She has used this information to take down Black Cat's criminal empire and to stop Jane Foster (Thor) from attacking her. Her medium awareness over the idea that she is in a comic book also allows her understand tropes, and comic book cliches, which she can implement to specific situations to gain an advantage, something which others often consider to be her sheer dumb luck.
