Edward Janeway was Kathryn Janeway's father, whose image an alien entity borrowed in an attempt to claim her after a shuttle crash.
Edward Janeway was the father of Kathryn Janeway and a Starfleet officer whose example shaped her career. He had died years before Voyager was stranded, and his loss still weighed on her. Len Cariou played him.
In Coda, after a shuttle crash left Janeway near death, she found herself trapped in repeating loops and then watching her own body as a disembodied presence. An entity appeared to her in the form of her father, gently urging her to let go and come with him into a peaceful afterlife. Janeway realized it was an alien that fed on the dying, refused it and was revived by her crew.
