Palaxia
Palaxia was a little girl who initially survived the deployment of the metreon cascade weapon on the Talaxian moon of Rinax. 

She was found by Neelix, who was among the search parties that traveled to Rinax looking for survivors. Palaxia was brought back to Talax, and Neelix stayed at her bedside over the next few weeks as she withered away, and eventually died. 

During a nightmare Neelix had in 2371, a vision of Kes claimed to be Palaxia and asked Neelix why he didn't help them. ()
