In FusionFall, Gwen was worried about the Fusion Matter infection spreading to the wildlife of Townsville Park and went to go help out there to keep it safe. She also met Bubbles and gets along well with her. She observes the Park's Fusion monsters' behaviors and characteristics closely, reporting them to Dexter and other scientists. Grandpa Max and Rex help out with a lot of her missions involving the Park. Gwen helps out during the war, not only in the Park, but in many other places of the universe as well. Her weapon is a Golden Shovel (a reference to "The Chefshank Redemption," in which her team won a golden shovel to use in the challenge).
