Evolved Human AbilitiesEdit

  • Enhanced Strength: Niki was strong enough to knock down doors and other obstacles with a single hit, throw people several feet across a room, Overpower Men several times larger than herself, literally rip people in half, break restraints capable of "holding down an elephant" with very little effort, rip the door off an office safe with her bare hands, she was able to lift a heavy set grown man with one hand, Broke a guards nose, folded a aron malsky in half, broke a set of hand cuffs, throws linderman across a room and into a wall, Smacked sylar with a parking meter, sent mohinder flying with one hit and broke his nose, knocked candice off her feet several feet across the room and give her a bloody nose, rip a door nob off with her bare hands, Yanked open a locked door, when angered she slamed a car door so hard that the window glass shattered, threw mich into a pile of rocks, broke a tazer, severly injured Dr. Witherson, broke a prison guards baton, Bashed down a wooden door, throw matt prkman through a window with one hand, pushed mohinder into a door, lifted bob bishop with one hand, and send D.L flying with one kick. Due to Niki's ability of enhanced Strength, Her body was naturally completely immune to the force she applied allowing her to perform her superhuman feats of strength without causing any damage to her body. For months, she could only utilize her power through her alternate personality, Jessica, who is much more violent than her normal self. In How to Stop an Exploding Man, Niki finally learned how to use her enhanced strength at will.


  • While Jessica has a tattoo of The Symbol on her upper right back, Niki does not.
  • Niki and Hal use more formal names for each other: Niki calls her father "Hal", and Hal calls his daughter "Nicole".
  • Niki is on the list.
  • Niki can communicate with her alternate personalities through reflective surfaces: whichever personality is dominant sees the alternate in the reflection. However, Matt Parkman heard thoughts of both personalities via his telepathy during one of their conversations (Run!). Niki and Jessica also communicated in jail sans reflective surface (Godsend). The significance of these unusual occurrences is unknown.
  • According to the cast commentary for Godsend, the cast members themselves believed that it was Niki — not Jessica — who broke the guard's baton. However, during the Wizard World Los Angeles panel, the writers entertained the possibility that Niki might "eventually" be able to access Jessica's power, indicating they believed she hadn't done so yet. Her use of enhanced strength in How to Stop an Exploding Man at Jessica's urging made reasonably clear that she had not knowingly accessed her power prior to her fight with Candice Willmer.
  • While a great deal of confusion about Niki and Jessica's relationship persists, Jeph Loeb stated in an interview that the crew "thought this was very clear on the air. Niki's power is the same as her alternate personality Jessica's: unbelievable strength. They're the same person. Niki discovered her special ability through her split personality, but it was always her ability."
  • According to Dr. Zimmerman, Niki's ability is the result of receiving the formula rather than a naturally inherited ability. (I Am Become Death)


  • The laptop Niki uses for runs Debian Linux and uses Gaim for instant messaging.
  • Niki never keeps peanut butter in the refrigerator. (Godsend)
  • The ABC Soap Opera One Life to Live is famous for being one of the first serialized dramas to tackle the topic of dissociative identity disorder (DID) in a real and serious way with a beloved lead character. That character was Victoria Lord (Viki), whose most active and dominate alter ego was named Niki. She also had a daughter who, through Niki's carelessness, was traumatized as a child and likewise developed DID. Her name was Jessica, and her main alter ego was named Tess.
  • According to a form found in Linderman's archives, Niki's Social Security number is 2574-87-5698. (The Hard Part)
  • A 2001 medical form for Niki has an address listed at the top: 348 South 4th Street, Portland, Oregon, 97209. It is unclear whether this was once Niki's address or whether this is the address of the form's originator. The medical form also lists Niki's age as 33. According to NBC's press packet, Niki would have been 28 in 2001. However, according to Nikki her birth certificate says she was born on August 24, 1974.
  • In New Orleans, Niki drives a Chevrolet with Louisiana license plates KMB801T.
  • According to the birth certificate Micah found on his computer, Niki weighed 6 pounds 14 ounces when she was born. She was born August 24, 1974 at 12:56 am in Beverly Hills at Our Lady of Perpetual Faith Hospital, and she was delivered by Dr. Zimmerman. Interestingly enough, Tracy Strauss's birth certificate lists the exact same information.
  • According to a court record, Nicole Sanders has had felony complaints brought against her for robbery, homicide [sic], and grand theft auto.
  • The same certificate lists Niki's birth mother as "Kelly Sullivan". This name probably came from the assistant to the executive producers with the same name (see Kelly Sullivan).
