Claire - She has the power of spontaneous cell regeneration, or she just heals.

Hiro - One of my favorite powers on the show, bending the space time continuum. So he can stop time, teleport and even time travel

Isaac - One very important character on the show. He can see/paint the future.

Nathan - Peters big brother, he has the very cliched power of flight and can even break the sound barrier.

Peter - One of the most popular characters (next to Hiro), he can absorb the powers of any other 'Hero' he meets.

Matt - Very suited for his job as a cop, he can read others minds.

Nikki/Jessica - Nikki has a split personality called Jessica that can take control over Nikki. Jessica naturally has super strength and Nikki obtains her strength through Jessica.

D.L - Simply put, he can walk through walls. He can even walk others through walls as well.

Micah - This special little guy can 'talk' to machines and make them do anything he wants. He is also very smart.

Ted - The power of radiation. Originally thought to be the cause of the New York explosion.

Sylar - His original power was to instantly find something wrong with a machine but has developed other powers by eating other 'Heroes' brains. His more dominant power is telekinesis.

Eden - Can hypnotize people.

Charlie - She can remember everything she reads.

Molly - She had an early appearance in the show when Matt first discovered his powers, but her power was not revealed in till later in the series where we find that she can find anybody, anywhere in the world.
