Rita had a brief and memorable appearance in Dead Avengers, a Chaos War mini-series in which Swordsman, Vision, Captain Mar-Vell, Deathcry, Dr. Druid and Rita played a role (as 'dead avengers' who had to save the living ones, during the event, when the living fell unconscious and only the spirits of the dead could fight to defend them). It was even implied that she escaped her fate, flying off in a Quinjet at the end, which seems like something a dead spirit wouldn't be able to do, but who knows if that was real or not...
I feel like I'm betraying Melissa Gold, whose turn as Songbird I loved, but I liked Rita DeMara way more than 'Screaming Mimi,' and if Rita became Songbird instead, back in the day, oh heck yeah!
