12. Rosalind Chao; Keiko O’Brien, TNG, DS9
Wife to Miles O’Brien, Rosalind Chao started in the Star Trek universe as Keiko Ishikawa but quickly became an O’Brien. Her character followed her spouse from The Next Generation to Deep Space Nine, and they eventually had a child. Chao, like her on-screen husband, has enjoyed a decent career outside of Star Trek. She’s stayed consistently busy since the shows ended, regular and walk-on roles in TV series. She’s that actress audience members always recognize, but can’t remember what from.
