Roma

The daughter of Merlyn, Roma took over his duties after he turned evil and lost to Captain Britain. As the Omniversal Guardian, she supervised the Captain Britain Corps. Roma's main involvements in the fate of Earth-616 include resurrecting the X-Men (including Captain Britain's twin sister Psylocke) after they died in battle fighting the Adversary during the Fall of Mutants. Before sending them to Australia, Roma gave Psylocke the Siege Perilous.

A few years later, Roma would also influence the Braddocks' lives by first asking Brian to rule the Overworld with his wife Meggan, then by taking away Psylocke while she was delivering the killing blow to the Shadow King under her twin's eyes. This latest action was in fact intended to add Betsy Braddock to the Exiles team.

In Fantastic Four Vol. 3 # 48, Roma is seen watching over the omniverse. Abraxus has been set loose from Eternity by the absence of Galactus. In his search for the Ultimate nullifier, The Human Torch and Nova set out to find it first which they do. Nova then turns against the Torch and states how she is angry about how Galactus ate her world and how she now serves Abraxus. She gives Abraxus the Nullifer and he appears in front of Roma magically. She tells him to cease his mad plot to remake the universe in his own image, he then thanks her for protecting Eternity all these years, kisses her on the mouth which gave her instant death. In the end, Galactus show up and effortlessly calls the nullifier to his person and sends Abraxas away.

Eventually, the Braddock twins reunited in the wake of [[X-Men: Die By The Sword:vol:19237]]. This crossover between the Exiles and New Excalibur saw these teams join forces to help Roma and Saturnyne fend off the attacks of Merlyn, who set his mind on reclaiming his throne, and Mad Jim Jaspers. The fight would reach its climax with Roma being killed by a Fury-infected Jaspers.
