Many science fiction TV shows have strange love stories and relationships. Peter Bishop (Joshua Jackson) with alternate Olivia (Anna Torv) on "Fringe" and Tyler (Logan Huffman) with the alien Lisa (Laura Vandervoort) on "V" are just a two examples. Those examples just scratch the surface. Only a few sci-fi love stories and relationships can be considered truly bizarre.
The Doctor and his TARDIS on "Doctor Who"
The Doctor (Matt Smith, in this case) has been traveling through time and space for several centuries in his trusty TARDIS (Time and Relative Dimension In Space), but never really knew the TARDIS until the episode "The Doctor's Wife."
In "The Doctor's Wife," the TARDIS matrix is transferred into the body of a human woman named Idris (Suranne Jones). Idris is the closest thing to a wife the Doctor will ever have. Unfortunately, she cannot stay in human form for long. She must return to machine form, breaking the Doctor's heart. It's both a beautiful and bizarre love story for true sci-fi geeks.
Love between strangers on "Stargate Universe"
The crew of the Destiny on "Stargate Universe" were trapped in a faraway galaxy, trying to find their way home. They used a device called a long-range "communication stone" to switch consciousness with someone on Earth. This consciousness swap allowed the Destiny crew to visit family and friends back home.
The person on Earth would basically donate their body to be used however the crew member wished. This sometimes meant the donor's body would be used to have physical relationships with people the donor would never meet.
Chuck and Ned on "Pushing Daisies"
Charlotte ("Chuck," portrayed by Anna Friel) and Ned (Lee Pace) had the perfect relationship. They had true love, and an exciting relationship. They always had fun together, and never wanted anyone else. Unfortunately, they could only touch through a layer of plastic, lest Ned kill Chuck instantly with the slightest brush of his hand.
Baltar and Caprica Six on "Battlestar Galactica"
The relationship between Baltar (James Callis) and Cylon Caprica Six (Tricia Helfer) on "Battlestar Galactica" started out as a real physical relationship. After Caprica Six's first body died, the relationship was between Baltar and an imaginary Caprica Six. The imaginary love story became truly bizarre when Baltar began to flirt, argue, make out, and even make love with what appeared to be thin air, in front of anyone who may have been present.
The love triangle on "Lexx"
"Lexx" was the most bizarre of all science fiction love stories. Zev (portrayed by Eva Habermann, then later by Xenia Seeberg as Xev) is a half love slave, half lizard girl. 790 is a severed robot head who loves Zev above all others, but has no body. Stan (Brian Downey) is the captain of the "Lexx," and is also in love with Zev. Zev doesn't care for them, however. Instead, she is in love with Kai (Michael McManus), a corpse who has been dead for over 2000 years. If that's not bizarre, nothing is.
