List of The 4400 characters
[4] Shawn Farrell, portrayed by Patrick Flueger, was born December 12, 1983, and disappeared April 22, 2001 from Highland Beach near Seattle, Washington, while with his cousin Kyle Baldwin.
Dennis Ryland, portrayed by Peter Coyote, was the original supervisor and director of NTAC (National Threat Assessment Command) during season one.
During season one, Ryland is constantly portrayed as sympathetic to the 4400 and darkly amused when he informs Skouris and Baldwin that it's their job to resolve the mystery of the 4400's new-found abilities.
However, as soon as Orson Bailey demonstrated his power of telekinesis, Ryland secretly ordered a separate investigation into the cause of the paranormal abilities, and possible methods of curtailing them.
In season three he begins working as the leader of a privately owned company, Haspel Corporation, a defense contractor aiding the NSA in the tracking of the Nova Group, a terrorist organization of 4400 returnees.
Lily Tyler, portrayed by Laura Allen (young) and Tippi Hedren (aged), was born August 4, 1966, and disappeared May 26, 1993, from Orlando, Florida.
Executive producer Ira Steven Behr originally pitched season three with the continuation of the character, but was told by the network to write her out of the show for "business reasons".
He is able to summon a tomato to his hand from a great distance, stop a tranquilizer dart, and even render someone unconscious by pinching off the blood flow to the person's brain.
He is able to effortlessly throw multiple full-grown adults through the air or pin them against walls- even if not in the immediate vicinity- as well as fling concrete barriers weighing hundred or possibly thousands of pounds with pinpoint accuracy.
Afterwards, she moved to attack the 4400 Center but ended up losing her abilities when her father used his telekinesis to inject her with a serum given to Tom Baldwin by the people from the future.
In the fourth-season premiere, she was visited in prison by Baldwin, who was looking for information on his missing girlfriend, Alana, believing Isabelle would have the closest connection to the people from the future.
During the episode "One of Us", it is revealed that the agent from the future who is possessing Tom Baldwin intends to restore Isabelle's powers via complete blood transfusion.
She studied at Cambridge University as a Marshall Scholar before returning to the states and earning a PhD in political science, specializing in conflict negotiation.
The shots he took disfigured his appearance by causing wounds on his chest and loss of his nails, though in exchange it granted him rapid (but inconsistent) healing of muscle tissue.
After a failed attempt by him and Tess to perform the same promicin-injection procedure on Diana Skouris, he shed his skin like a snake, revealing an untarnished appearance.
After being infected by a promicin-inducing virus in "The Great Leap Forward", Marco can seemingly teleport to any place he is thinking of, as he appears in Promise City after looking at a photograph of the location.
In the episode "Terrible Swift Sword", Jordan Collier receives help from 4400s with the ability to trace people to track Kevin and Tess and discovers where they are hiding; he then goes to visit them and enlists them in his plan to steal Dennis Ryland's stores of promicin.
April becomes depressed and coming to the realization that her life is pointless she takes a promicin shot, gaining the ability to make anyone truthfully answer any direct question she asks.
After a larger controversy where he escaped re-capture by NTAC thanks to Alana Mareva, Tom finally fulfilled his promise to Gary and helped him flee from the United States.
In Tiny Machines, Danny, having heard about the test being developed by Kevin Burkhoff to determine whether or not an individual can tolerate promicin, approaches his brother at the 4400 Center.
After doing so, Danny was unharmed - however during a visit home, in which he reveals that he is now "P-Positive" to his mother over drinks, the latter begins to exhibit signs of an aneurysm similar to those induced when individuals who can't tolerate promicin take the shot.
In the fourth-season episode "The Marked", it is revealed through Curtis Peck's ability that Ross was among a ten-strong group of prominent individuals in society who have had their consciousness "hijacked" by the 4400-opposed faction.
A side-effect of this operation leaves a mole underneath the subject's left earlobe, along with a vaguely X-shaped mark (hence the title of Curtis' Independent film and thus the episode).
In "Audrey Parker's Come and Gone", Cassie instructs Kyle to steal the book describing the White Lights prophecies that he had read in the previous episode.
Kyle does show up at the appointed time, and is there to witness a car crash that leads to the liberation of Isabelle Tyler, in transit to her new holding facility.
When Isabelle, under the influence of the now-Marked Tom Baldwin, turns her back on the movement and kidnaps Jordan Collier, Kyle angrily accuses Cassie of deceiving and manipulating him.
Her response indicates that Isabelle's betrayal was all part of a larger plan, and that in Jordan's absence it will fall on Kyle to assume leadership of Promise City.
In the follow-up book, Promises Broken by David Mack, Kyle finally realizes that Cassie is not always looking out for his interests and was leading him in dark directions by sometimes speaking through him and even using him as her puppet.
The only explicitly revealed agents thus far are Drew Imroth, the CEO of the Ubient Software Corporation; Rebecca Parish, the director of National Intelligence; and Matthew Ross.
When Tom Baldwin is sectioned in a mental hospital for reporting Curtis Peck's claims of conspiracy, The Marked implant a sleeper agent inside him.
