Elizabeth Twoyoungmen is the daughter of Michael Twoyoungmen of the Canadian superhero team Alpha Flight. She became estranged from her father at the age of four following the death of her mother following an illness. Michael, a physician, had promised to save her and his failure led Elizabeth to be bitter and resentful toward him.
The current team roster is confirmed to be U.S. Agent, Arachne, Beta Ray Bill, "someone in a Guardian suit," and Talisman. It has also been confirmed that former Alpha Flight member, Sasquatch, will have a role in this book; however, it has not yet been revealed whether he will be a member of Omega Flight or simply a supporting character.
