Page "Outsiders (comics)" Paragraph 17

During the initial confrontation with the vampires, Looker is ( apparently ) killed.

Hiding out in Gotham City, the Outsiders experience another loss as Technocrat's wife Marissa and Halo are killed during a fight with Batman ( actually the man standing in for Bruce Wayne, Jean-Paul Valley ).

However, Halo's spirit survives in the reanimated body of Marissa.

For some time afterward, Technocrat has trouble accepting that his wife ( whose body is still walking around ) is dead.

Eventually it is discovered that Looker is not dead, but undead.

The Outsiders find her, and free her from the vampire's control.
