Hiro Nakamura (Masi Oka) -- Time manipulation / Time travel /Teleportation -- Japanese man traveling with his friend Ando. Powers are somewhat iffy, as he sometimes cannot manipulate the space time continuum at all, and at other times will overshoot his intended destination by miles and/or centuries. The son of a successful Japanese businessman, Kaito Nakamura.
Claire Bennet (Hayden Panettiere) -- Cell regeneration/ Self-healing -- "The cheerleader", Mr. Bennet's adopted daughter; biological daughter of Nathan Petrelli and Meredith Gordon. She ran away from first "PrimaTech Paper", in Texas, and later her bio-dad and grandmother, in New York. She was voted her high school's Homecoming Queen thanks to Zach and the "unpopular" voters. Her blood can be used to heal others, not just herself.
Niki Sanders (Ali Larter) -- Superhuman strength -- Micah's mom, married to D.L. Is afflicted with the multiple personality disorder that apparently is a result of the stress the power takes on the person's mind. MPD isn't considered a power as it can affect any of the heroes, not just Niki. Her power is her superhuman strength. After this she left Micah with family of DL's and went to the company to get "cured". While there, she was used by Matt's father to try to kill Bob, but then was injected with the "Virus", the new threat. In 2.11 "Powerless", Niki sacrifices herself to free Micah's kidnapped cousin, Monica Dawson, from a burning building.
Peter Petrelli (Milo Ventimiglia) -- Power mimicry -- A registered nurse, Nathan's brother, was Simone's lover after being her father's Hospice nurse. Thought by outsiders to be mentally unstable. The first season's plot semi-revolved around the possibility of him exploding and destroying New York. As of the second season's premier it seems Peter is alive, but has no idea as to who he is or what he's capable of in terms of his abilities. He survived the "explosion" after he absorbed his niece Claire's regenerative capabilities. After dropping Nathan off at a hospital, he is taken captive by The Company. He breaks out with Adam aka Kensei, who later convinces Peter to help release a lethal virus. Nathan and Matt try to stop them, and are joined at PrimaTech by a vengeance seeking Hiro.
Nathan Petrelli (Adrian Pasdar) -- Flight --
Politician, Peter's brother. Claire Bennet's biological father. Appears his first experience with flight (that we know of) partially caused the accident in which his wife was paralyzed. Peter also dreamt the dream as it was happening/right before it happened. As of the end of "How to Stop an Exploding Man", newly-elected Nathan flies Peter high above the earth, saving New York from its seemingly unavoidable future. Due to this it is assumed he died, but returns in the second season as a much different man. It is said that since the occurrences in the season one finale he's become a drunk, driven away his wife and children, and it seems has left his elected position of congressman.
Matt Parkman (Greg Grunberg) -- Mind Reading, later fully developed Telepathy/Mind Manipulation -- Dyslexic police officer turned bodyguard after six-month duty suspension after a raid on PrimaTech paper factory to find where Sylar was being held was unsuccessful. Also, trying to mend his marriage to Janice, who is pregnant. As of the end of "How to Stop an Exploding Man", Matt is in critical condition. As of the beginning of season two, "Four Months Later", Matt and Mohinder are living together and watching over Molly Walker. Matt is hired by the NYPD after finally passing detective's exam, and claims to have split from his wife and unborn baby. In "Five Years Gone", Matt and Janice's child is in hiding and referred to as "Matthew", but in Season 2, Matt claims the baby is not his, but his ex-partner Tom McHenry's, and he is divorced. But when trapped in his father's psychic projection, his wife accuses Matt of abandoning them. His powers have evolved, and now instead of only reading thoughts he can put thoughts into people's heads, controlling them like his father, Maury, the "Nightmare Man" Molly is afraid of.
Gabriel "Sylar" Gray (Zachary Quinto) -- Numerous stolen abilities -- "Sylar" is the alias used by Gabriel Gray, a watch maker turned serial killer who absorbs the powers of those with superhuman abilities by killing them and dissecting their brains. His own original power appears to be an instinctive sense for how things fit together and how they can be fixed if broken, something that served him well both in his watchmaking career and, subsequently in his drive to integrate the abilities of others into himself. He credits Chandra Suresh with turning him into the serial killer he is today. He was responsible for many deaths including Brian Davis, Zane Taylor, Charlie, Jackie, and Molly's parents. At the end of "How to Stop an Exploding Man", his condition is uncertain, as he appeared to have been stabbed to death. You can see Sylar survived as the receding view of the last battle ground shows a blood trail leading from where his body had been lying to an open sewer manhole. He was saved by Candice Wilmer who took him to South America to mend under instructions from The Company.
"The Haitian" (Jimmy Jean-Louis) -- Power negation / Memory suppression -- Works with/for Mr. Bennet but seems to have a scheme of his own. The Haitian wears a necklace with a strange symbol resembling an RNA molecule*, a recurring symbol on the show. While he has no name referenced in the series yet, this is how he is referred to by the writing team. (*The symbol had been presumed to be an RNA molecule throughout the duration of the show, however Ando recently identified it as a combination of two Japanese characters: Sai [great talent] and Yo [Godsend]. This was revealed in the episode Godsend. RNA could still play a role in this, as nothing has been finalized.)
D.L. Hawkins (Leonard Roberts) -- Phasing -- Most likely description for his power is being able to oscillate the atoms in his body at/near the speed of light. Was framed by Niki's alter-ego, Jessica, and jailed for stealing Linderman's two million dollars. Later killed Linderman for reasons unrelated to the money. Married to Niki, father to Micah. Was killed when he tried to rescue Nikki (Currently under possession of a new personality, Geena) from LA. Was dead before the first episode of the new season.
Micah Sanders (Noah Gray-Cabey) -- Technopathy (can manipulate technology with his mind) -- Child prodigy son of Niki and D.L. Read the same Mendez comic book Hiro had, which had not yet been released. Kidnapped by Candice Wilmer. Responsible for Nathan Petrelli's landslide victory in the 2006 election. Currently living with his father's relatives in New Orleans.
Sanjog Iyer (Javin Reid) -- Spirit Guide/Dream Traveler (can enter people's dreams and show them the past) -- Child living in India who guides Mohinder Suresh to the realization that he was the second child born to his parents, amongst other things regarding his father's past. Largely because of this boy, Suresh travels back to New York where he begins his search for Heroes with renewed fervor.
Isaac Mendez (Santiago Cabrera) -- Precognition -- Paints the future while in self-induced, trance-like state. Recovering from a heroin addiction. Appears to have an attraction to Simone. (The show started with Isaac & Simone in a relationship, which ended due to Isaac's heroin addiction, after which Simone & Peter became involved). Killed by Sylar after finishing the final "Ninth Wonders" issue and handing his sketchbook over to his messenger. A series of eight paintings he left behind drive several cast members in season two. It is unknown how many paintings he had left behind.
"Claude Raines" (Christopher Eccleston) -- Invisibility -- Found by Peter and seems to have been in control of his power for some time. The "Invisible Man". Lives above the apartment building that Simone's father owned & lived in, and many premonitions occur from this vantage point. His real name is unknown - he likens himself to the actor Claude Rains, who played the lead character in The Invisible Man. Was teamed with Mr Bennet shortly after Bennet was hired by The Company. When The Company found out Claude may have been working for outside interests to protect people with powers, they arranged to have Bennet kill his friend. Claude knew about their plan, due to his invisible spying, and made arrangements to disappear, eventually finding his way to New York City, possibly under the protection of Charles DeVeaux, explaining his residence on top of DeVeaux's building.
Meredith Gordon (Jessalyn Gilsig) -- Pyrokinesis --
Claire's biological mother. Supposedly died along with Claire in a building fire, though both survived. Character seems "divided" between a genuine concern for Claire, and a long-nurtured grifter mentality to extort money from Nathan, cheating Claire in the process. Claire suspected that it was all about money for her.
Eden McCain (Nora Zehetner) -- Persuasion -- "Friends" with Mohinder and his father, Chandra Suresh. Works for Mr. Bennet. Also known as Sarah Ellis. Committed suicide by turning gun on herself to keep Sylar from gaining her power after a failed effort to persuade him to kill himself.
Ted Sprague (Matthew John Armstrong) -- Radiation Channeling --
High amounts of radiation (at least 1800 curies) emit from his body during times of extreme emotion. Ted was initially suspected to be "Sylar", due to his wife's oncologist's death by immolation. Matt was able to determine that the death was an accident, caused by Ted's power. Ted cannot yet control his power, and he is also responsible for his wife's terminal cancer. Ted has the same mark on his shoulder as Matt, a symbol that resembles an RNA molecule, implying that the two are somehow connected. The symbol has since been linked to a specific type of drug-administering device, with 2 particular slash lines, that appears to have been used on all the heroes who have been captured, hence the matching lines. Killed by "Sylar" in the penultimate episode of the first season, meaning Peter is not the only potential destroyer of New York.
Charlie Andrews (Jayma Mays) -- Instant Learning-- A waitress in a small diner, Charlie managed to learn a conversational level of Japanese by spending just a few hours speaking with Hiro and Ando, but was shortly thereafter killed by Sylar for her power. Hiro tried to save her by going six months back in time by using his power, but discovered that she'd already been diagnosed with a terminal disease. Hiro loved her, and right after this trip is when his powers weakened (possibly fueled by his sense of failure and futility about them).
Hana Gitelman (Stana Katic) -- Cyberpathy / Cyberkinesis -- Hana contacts Ted Sprague out of the blue while he hides out in the Nevada desert. She explains to him about the marks gained from his abduction and shows her own slash lines. She explains they are from a type of gun that injects a radio isotope used for tracking. She also demonstrates her power by controlling Ted's computer and chatting to him using an Instant Messenger feature despite him not being connected to Internet. She claims that she can download "Wi-Fi" signals - pull E-Mails out with her head and access the Internet. She also says she can track Mr. Bennet, the one who abducted them, so Ted could "nuke" him.
Zane Taylor (Ethan Cohn) -- Molecular Manipulation -- Zane was in contact with Mohinder Suresh. Sylar showed up at his door instead and impersonated Mohinder. Zane was quick to allow Sylar in. Inside could be seen a lot of liquid materials on the floor. Zane demonstrated his ability: molecular manipulation to melt materials. Sylar seemed impressed. Later, we see the real Mohinder show up and this time Sylar is impersonating Zane. Having killed Zane and acquired his power he was easily able to convince Mohinder he was Zane and offered to travel with Mohinder to visit the others who had abilities, arguing he could demonstrate his own gift to help win their trust. Mohinder agreed, but it is unknown at which point he discovered that it was actually Sylar.
Dale Smither (Rusty Schwimmer) -- Super Hearing -- Dale is a female mechanic who is approached by Mohinder at her garage. With Mohinder is Sylar pretending to be Zane. At first she seems reluctant to help them until the fake Zane demonstrates his ability by melting her wrench. She explains she had super hearing. That a cockroach in her neighbor's house was like a marching band in her room. She also said that after she learned to control it she could hear rain from forty miles away and could even listen to a person's moods by hearing their heartbeats. She asks that they return tomorrow for talking. That night, however, Sylar meets her again. She asked why she didn't hear his footsteps and he replied saying there weren't any. She then asks what that sound in his heart was. He replies with "Murder." When Mohinder and fake-Zane return the next day Sylar is having difficulty controlling his newly acquired Super Hearing and Mohinder finds the deceased Dale. They flee the scene, calling the police from the road.
Candice Wilmer (Missy Peregrym) -- Illusion -- Candice works for "The Company" that Mr. Bennet works for, and can make others see what she wants them to see. In the episode "Parasite," Candice walks in as the police are about to discover Simone's body in Isaac's apartment, and appears as be a very alive Simone. She later assumes the form of Mrs. Bennet in order to find out whether he is still trying to find Claire, then calls in the reinforcements and resumes her own form. She has hinted that she is constantly in disguise, and eats like she doesn't care about what she looks like. When Sylar kills her in the third episode (Kindred) of season 2, her shape returns to her real form, an obese woman.
Mr. Linderman (Malcolm McDowell)-- Can Heal Others -- Las Vegas based Corinthian Casino owner with ties to mob. Former owner of the sword Hiro needed to regain his power. Buyer of many painters, including Isaac Mendez, claims he has several other psychic painters in his personal gallery. Jessica's boss. Nathan Petrelli was trying to set him up by wearing a wire for the FBI, but then decided to just kill him after being warned by Nikki. He hesitates when Linderman admits to knowing everything about him and the other heroes. As of the end of "How to Stop An Exploding Man", Linderman is dead, killed by D.L. Hawkins reaching into his skull and possibly removing part of his brain.
Molly Walker (Adair Tishler) -- Can Find Others -- Little girl whose parents have been murdered by a serial killer believed to be "Sylar". She first appeared in Heroes: Chapter Two 'Don't Look Back' (#1.2) Her powers are revealed in Heroes: Chapter Twenty-One 'The Hard Part' (#1.21) as being able to locate anyone. Currently her powers don't work as she is dying. Mohinder is trying to heal her with his own blood - as she has the same illness that killed his sister. Is living with Matt and Mohinder in Mohinder's apartment as of season 2. After being cured, she was attacked by "The Nightmare Man" when Matt tried to get her to track his father. The father had trapped Molly in a nightmare, leaving her body in a coma. Note: A "James Walker" appears in Chandra Suresh's database, and may be Molly's late father, who was found frozen and scalped by Sylar. Her mother is seen pinned to a wall by silverware, dead but otherwise untouched, so it is doubtful she had powers.
Charles DeVeaux (Richard Roundtree) -- Dream Walking -- He was the father of Simone Deveaux, and a former hospice patient of Peter Petrelli. Simone believed that Peter was "like a son to him" and that Charles improved under Peter's care. At the moment he died of natural causes, Peter had dream where Charles spoke to him. Peter's first instinct to fly was suggested by a dream Charles told to Peter. His appearance in "How To Stop an Exploding Man" shows that he was not simply Simone's father, but also the most kind-hearted and insightful of the previous generation's "heroes". Can sense Peter's projected presence, since he knows Peter is present, even though his projection is "invisible" to others around Charles.
Angela Petrelli (Cristine Rose) -- unconfirmed, possibly biorhythmic control -- Mother of Nathan and Peter. Admits to plotting the destruction of New York with Linderman. When "The Twelve" concept is introduced, Tim Kring stated all twelve members had powers, and that each would be revealed in Chapter Two: Generations. (Presumably, this idea was one of many plot points curtailed due to the then-upcoming Writer's Guild Strike.) The only hints at Angela's powers have been: inconsistencies with reports of her husband's (known as "Dallas" Petrelli in online comic) death (heart attack or suicide); a comment to Peter in 1.12 "Godsend" deleted scene about him having a heart attack as she is trying to calm him down after waking from his coma; in 2.8 "Four Months Ago", the fact she is rubbing her daughter-in-law Heidi's arms while trying to convince her to leave the hospitalized Nathan is obviously impressed upon; and when Peter meets her one year in the virus-ravaged future, he only regains some of his memory after she touches him. She meets with Kaito when both receive a photographic death threat from Adam. When Kaito is killed, she turns herself in, claiming she killed him because of spurned love, admitting they once had an affair, years previous. She is attacked in custody while alone (presumably by Maury Parkman), and later reveals to Matt she knew his father and where to find Victoria Pratt, another member of their group, "The Twelve." Pratt may be the only one to find the virus Adam wants to unleash, but she has already been killed by Adam (with a still amnesiac Peter) before Matt can get to her.
Maya Herrera (Dania Ramirez) -- Plague possession -- Introduced in Season Two, twin sister of Alejandro Herrera. Discovered on her brother's wedding day, that she has the power to kill by conjuring a unknown virus by pure thought after she discovered her brother's wife cheating on him. Whenever threatened or in a state of fear, her eyes turn black and she makes anyone within close quarters to make their eyeballs, ears, and mouths bleed out a black-putrid fluid. Only her bother, is immune to her ability and can stop her from hurting others. They go on the run from the law after she inadvertently kills her brother's entire wedding party from their home in the Dominican Republic, across Central American and Mexico hoping to reach New York to find Mohinder Suresh hoping he has the research to cure her. Paths with Syler cross when they pick him up in Mexico, after he escaped from 'the Company's' imprisonment and tricks her into helping him too find Suresh so he will regain his powers.
Monica Dawson (Dana Davis) -- Ability to mimic others actions almost instantly upon viewing -- Introduced in Season Two, and the older cousin of Micah Sanders, and resides in New Orleans, she discovers that her mind can imitate any action that she seesscreen from cooking shows, to wrestling, to any action stunts. Although most of the things she learned to do were from TV shows or on the screen of a portablevideo player, at one point she did some complicated skipping manouvers upon seeing it happen on the street. Mother died in Hurricane Katrina, and wants to leave New Orleans to make a new life for herself. Micah helps her to understand her abilities. Saved from a fire by Niki Sanders, who is considered dead at this point in time, in the season 2 finale.

Took his Japanese name as a 'ronin', assassin-for-hire. Met with Hiro who time traveled back to Japan and persuaded him to accept his destiny as Japan's hero. Unfortunately, Kensei, after discovering his powers, used his abilities for his own self-interest by turning against Hiro and forming an alliance with a rouge warlord, named White Beard, to overthrow the Shogunate to take power for himself. With his powers of healing and regeneration, he does not grow old either and has lived though the centuries under various names, as well has his real name Adam Monroe.
