9. Character Analysis

10. Peter Bishop
Peter Bishop is the son of mad scientist Walter Bishop, and a member of the Fringe division.
In the show's second season it is revealed that Peter is actually from a parallel universe from where he had been kidnapped by Walter after this universe's version of Peter died at a young age.
He is a genius with an I.Q. of 190, a college drop-out with gambling debts

11. Olivia Dunham
Olivia Dunham is a young FBI agent assigned to a multi-agency task force of the U.S. Department of Homeland Security called the "Fringe division".
She is brought aboard the Fringe division after her boyfriend and fellow agent, John Scott, dies in a Fringe-related case.
 As the series progresses she comes to learn that, as a child, she was a test subject for Walter's Cortexiphan trials, giving her some weak psycho-kinetic abilities including the ability to cross between the universes.
Over the course of the show Olivia develops a romantic relationship with Peter

12. Walter Bishop
Walter Bishop is a former government researcher into fringe science with a recorded I.Q. of 196.
He was institutionalized after a lab accident which resulted in manslaughter charges.
Having been locked up for 17 years in a mental institute prior to becoming assigned to the Fringe division, Walter often expresses wonder at modern technology, and seems to be disconnected from the world, sometimes leaving his son to decode his rantings for others.
He often says things which seem so obvious that no one else wants to say (or thinks necessary) and tends to

13. Phillip Broyles
Phillip Broyles is a Homeland Security Special Agent and head of the Fringe division, which was established to investigate a series of terrorist/unexplained phenomena.
While Broyles comes off as professional and by-the-book, he is surprisingly flexible when it comes to dealing with the unusual circumstances of Pattern-related cases.
Little is known of Broyles' past. He has been involved in the military, citing experience as a Colonel in "six wars".

14. Captain Lincoln Lee
Captain Lincoln Lee is a team leader within the parallel universe Fringe division, working with
Alt-Olivia and Alt-Charlie.
Agent Lee was originally introduced in the first part of the season two finale, when the
Fringe division of our dimension goes to "the other side" to get Peter back.
The showdown Fringe divisions leaves Lee with third degree burns covering 90% of his body. Thanks to the advanced nanotechnology known in the other dimension, Lee does not stay away from duty for long, and after a three months medical treatment he is completely recovered.

15. Astrid Franswoth
Astrid Farnsworth is an FBI Junior Agent who serves as Olivia's assistant. She is stationed in the lab with Walter, who can never remember her name (e.g. calling her "Asterix", "Aspirin", "Asteroid", etc.).
Though her work is mostly clerical, she has a number of skills which come in handy during their cases; cryptanalysis, knowledge of Latin, linguistics, computer hacking, and so forth.
Despite being a main character for nearly three years, Astrid's personal life and past have yet to be examined in depth.

16. Nina Sharp
Nina Sharp is the executive director of Massive Dynamic, and has run the business since William's departure to the parallel world.
Nina has had long personal ties with Walter and romantic interactions with William. One of her forearms is a highly-advanced prosthetic arm, having lost her arm while trying to prevent Walter from crossing over to the parallel universe in 1985.
 Nina is often cryptic and cautious of interacting with the Fringe members; though she will provide Massive Dynamic's services when necessary, she does not always reveal the full truth

17. Charles "Charlie" Francis
Charles "Charlie" Francis is an FBI Special Agent, who holds the position of a supervisor.
He is close friends with John Scott and Olivia. Olivia often comes to him with requests for manpower and other resources.
Charlie is later promoted to Second-In-Command of the Fringe division, making him the immediate subordinate of Broyles.
In the season premiere of season 2, Charlie is killed by a shapeshifter who takes his place and burns his body in a hospital furnace.

18. John Scott
John Scott (played by Mark Valley) is an FBI Special Agent who, in the pilot episode, is Olivia's partner and lover.
During an investigation of a flesh-dissolving toxin, John is exposed to the toxin after the lab producing it explodes with him nearby.
He is placed in a medically-induced coma, and during this time Walter devises a procedure to link his mind to Olivia's in order to gain information about the suspect who caused the explosion

19. William Bell
William Bell (played by Leonard Nimoy) is the founder of Massive Dynamic and the former lab partner and friend of Walter.
William is mentioned through season one, showing several ties with Walter's past and the study of the parallel world, including participating in the
Cortexiphan tests. Sometime after Walter brought Peter from the parallel universe, William convinced Walter to allow him to remove pieces of his brain and implant them in other patients to keep the knowledge of dimensional travel safe; this process led to Walter's mental instability and institutionalization. The two parted ways, William going on to form Massive Dynamic.

20. David Robert Jones
David Robert Jones (played by Jared Harris) is a biochemist and former employee of William
Bell and Massive Dynamics, a connection that wasn't revealed until the season one finale.
 Over the course of the first season, he is also proven to be the leader of ZFT, the organization responsible for most incidents investigated by the Fringe Division during season one.

21. September
September (played by Michael Cerveris), often referred to as The Observer, is a mysterious figure seen at the scene of many Pattern-related events.
Like other Observers that have appeared on the show, September is only seen wearing a plain black suit and black fedora, and is pale, bald, and lacks eyebrows.
They exhibit several strange mannerisms such as awkward phrasing when talking, a high tolerance to spicy foods, and the ability to appear or disappear when one looks away.

22. Sam Weiss
Sam Weiss (played by Kevin Corrigan) is a friend of Nina Sharp who operates at a bowling alley, and helped her with her physical therapy process after she lost her arm.
After Olivia's first visit to the parallel universe, he helps Olivia regain her ability to walk, partially through showing her how to bowl.
He begins to establish a friendship with her, and Olivia pays him another visit after learning the truth about Peter's origin.

23. Shape Shifters
Shapeshifters are androids from the parallel universe, possessing superhuman strength and damage thresholds, and acting as soldiers in the war between the universes.
This process occurs after the shapeshifter has killed the target prior to the transformation; without the device, the shapeshifter is locked in its current form
They are able to take the form of any person by using a unique device that plugs into the roof of their mouth and the mouth of the target.
