I'm sensing some family issues in Star Trek. Let's take a look.
TNG (All characters have lost at least one parent. 7 mothers dead; 6 fathers dead) Picard: Strained relationship with father; not much info on monther Riker: Mom dead; Strained relationship with father. Data: "Father" and "mother" were his creators; both die Worf: Mother and father are dead Geordi: Mother dead and father alive; but he was definitely a momma's boy Troi: Father dead; mother is annoying Beverly: Both parents dead Tasha: Both parents dead Wesley: Father dead
DS9 (4 mothers dead, one left; 2 fathers dead) Sisko: Mother "dead"; Father is a stout creole cook Kira: Mother and Father dead Odo: Parents are evil galactic overlords O'Brien: Mother dead; father initially disappointed, but later proudest man on Earth. Jadzia: Lived with both parents growing up Bashir: Strained relationship with parents Quark/Rom: Father dead; mother is stubborn Nog: Mother left; lived with father Jake: Mother dead; lived with father Ezri: Father unknown; strained relationship with mother
VOY (3 mothers dead; 4 fathers dead, one left) Janeway: Father dies after her childhood; mother still alive Chakotay: Raised by father; little info on mother Tuvok: No info. Doctor: Father was his creator Torres: Father left; mother is Klingon Kes: Species only lives eight years Neelix: Raised by parents; both killed during war Paris: Overbearing father; not much info on mother Kim: Both parents living Seven: Parents are assimilated; father presumed dead
ENT (3 fathers dead) Archer: Father dies; not much info on mother T'Pol: Father dies; strained relationship with mother Tripp: Lived with both parents Mayweather: Lived with both parents; father dies after launch of Enterprise Hoshi: Has a mother; character was, sadly, poorly underdeveloped Reed: Lived with father and mother Phlox: Any definition of family cannot apply to that species
Fortunately, patricide seems to decrease with each new series. Although, fathers still bear the brunt of the deaths. The only exception to that trend was DS9, showing why that series was awesome. :p
