She was in a Super team, the Phantasmics, with Everseer, Psychwave and Macroburst and those three are killed in quick succession. Omnidroid V1 kills Psychwave and Everseer, Macroburst destroys the V1 and then he's killed by the V2. V2 then moves to other Supers.
From the timeline it looks like the rest of the Phantasmics reunited to fight the Omnidroid together. But Plasmabolt didn't reunite with the Phantasmics. If she was going to go back to Super work it would have been with them.They might have reached out to her but she got enough satisfaction from her civilian life not to go. She didn't die.
