During the events of the Chaos War, Rick Jones' wife Marlo was being sought out by a resurrected Abomination and the demon ZOM because of her one-time connection to the entity Death. Death had left a trace of herself in Marlo and the Abomination and ZOM were sent to collect her and use her power to claim the lives of all those who were asleep and/or dead. The Hulk family hurried her away and attempted to shelter her in a bunker powered by Skaar's Old Power. Before Marlo would enter the bunker, she tapped into the remnants of Death within her and resurrected Hiroim the Oldstrong, Glenn Talbot, Hulk's late wife, Jarella, and Doc Samson to help them with the upcoming battle. Jarella was integral in defeating the resurrected demon form of Bruce Banner's father, Brian Banner.
