Marlo returns. But she’s dead?!? Yes. Yes she was.
Genis Vell, using his cosmic awareness, realizes that the energies she used to return from the dead–which also gave her super powers, will kill her.
So Genis Vell goes on a quest to save her. Into the future. Where he learns that most of the world is dead, with what is left of humanity enslaved by a collective imperialist government made up of a Shi’ar, Skrull, and Kree alliance. Genis himself is old and sickly, and attended to by his son, Ely-Vell.
Earth 616 Genis-Vell manages to incorporate himself into his own future body to wage a revolution against the colonizers. He then goes even further into the future, where his efforts to free humanity are looked upon poorly.
Meanwhile, in the present day, Marlo is still alive. Magus–the evil, future version of Adam Warlock–is trying to kidnap her and get the secret of her abilities. Marlo is defended by Moondragon and Phyla Vell.
They’re losing the battle.
In the future, we see that Ely Vell is Magus’ ally–and has caused all the things happening to Marlo in the present 616 timeline. To resolve the terrible future timeline’s connection to the 616 timeline, Genis Vell must kill his own son. He then returns to his own timeline to find Phyla and Marlo and tell her that he can’t stave off her inevitable illness.
Marlo is reunited with Rick. Genis murders his infant son to stop the time loop from recurring.
It’s amazing how this series jumps from humor, to love, to harrowing death like the sequence above. The range of this series is fantastic.
This arc is the penultimate one of this Captain Marvel series. After this, it’s one more issue and then the series ends.
