- "I am not afraid of you!"
- ―Petra Larsen to Melinda May
Larsen and her boyfriend Jakob Nystrom discovered an ancient manuscript detailing the hidden locations of the ancient Berserker Staff. The pair believed that finding the staff was the key to ascending to Godhood. After locating the first piece in the Trillemarka National Park in Norway, Larsen touched the staff fragment with her bare hands; she screamed as the rage inside her built up. When a park custodian approached her, Larsen hit him in his chest and sent him flying backward. Larsen, Nystrom and their followers then started hate-fueled riots in Oslo, Norway proclaiming "We Are Gods".
Larsen, Nystrom, and their followers gained possession of the second piece of the staff after taking it from Professor Elliot Randolph in Seville, Spain. Randolph was secretly the ancient Asgardian "Warrior Who Stayed" who hid the staff in the first place and he sought to find the pieces before the Paganists.
Larsen and the Paganists then traveled to Ireland to find the final piece. There they were confronted by a S.H.I.E.L.D. team led by Phil Coulson who were led to the location by Randolph. The paganists were taken out in physical combat by Grant Ward and Melinda May, with Larsen being defeated in combat with May, and the Berserker Staff took into S.H.I.E.L.D. custody.
- Berserker Staff: Larsen used the Berserker Staff to enhance her strength. She used it to attack a park custodian and Melinda May.
