I realize that this is talked about in pieces all of the time...but I wanted to give a few of my ideas...and I'd like to hear some agreements or disagreements or such.
Now, some of these are based on me believing that Maury Parkman is the one killing everybody, but I'll get to that later.
---------------------------------------------------------------------------------
Linderman - Healing things (not himself though).
Maury Parkman - Telepathy (strong)
Charles Devereaux - Precognitive dreaming
Bob - Metals into gold? Possibly changing one substance into another.
Adam Monroe? - Possibly healing himself.
Kaito Nakamura - Creating full clones of himself at will, making them disappear at will.
Angela Petrelli - Telekinesis
Arthur Petrelli - No idea...
4 Unknowns...???
REASONING -
Linderman - duh.
Maury - we've seen it in action against Matt, Nathan, and Molly.
Charles - the first power peter displayed was the ability to dream about the future. However, I can't remember if Peter had met Charles yet in the "6 months ago" episode. If he hadn't, then I believe that the precognitive dreaming power would have been Arthur Petrelli's, not Devereaux's. However...the final or next to last episode of Genesis had Charles Devereaux having a conversation with Peter on Peter's roof in an event that he never witnessed before. Sooooo....peter actually may have either dreamed it, and Devereaux had done the same so that they could hold conversation since devereaux predicted each line; Ooooor Peter actually used Hiro's power plus Claude's power to travel back in time to when Devereaux was alive but which would Still mean that Devereaux dreamed that peter was there, and so he held real conversation with him. ....whew.
Bob - metals into gold or substances into other substances. We've seen the spoon go gold.
Adam Monroe - I read a convincing argument that Adam Monroe is actually the Takezo Kensei from the past. So, I think he's a 400 year old hero. Whitebeard's flag symbols appear in Adam Monroe's apartment when Peter goes there in Montreal.
now HERE's the part where it all depends on whether or not Maury is the one killing people. Since Matt found Bob's death picture in his apartment, I'd say there's a good case for it. But Matt and Nathan probably would have killed each other had it not been for Matt breaking the telepathic world surrounding them. Also, Maury acts evil.
Kaito Nakamura - Cloning himself. Ando sees someone kill Kaito. The person is in a shroud. They LOOKED small, but then so does Kaito, to an extent. Either way, he could have cloned someone else. The person who killed him is not there when Ando looks over. So, the person could have been a clone conjured by Kaito who disappeared when Kaito died. But why would he kill himself? Maury. Maury is a powerful, nightmarish telepathic who can get people to go into their own minds and essentially start killing themselves without control over it. The only person who HAS shown control is Matt, in one, but possibly two instances. So, Maury may have gotten into Kaito's head, gotten him to clone someone and gotten Kaito to have his own clown attack him. Additionally, Kaito was exceptionally good at swordplay. And how could one be so good without a ton of people knowing about it or being aware? If you could clone yourself to fight, or clone others, you would have an infinite number of bodies to fight. Soo.....
Angela Petrelli - I'm saying this for a few reasons. The first is that it's one of Peter's unexplained powers (as far as I know). He never knew the telekinetic guy six months ago. Never met him. He had telekinesis before he met Sylar (but whose learned abilities I don't think he can take anyway, only his ability to learn), but it's never explained how he got it. Another reason I think Angela would be that person is that to start off the first season she steals a pair of socks "to feel alive again." How did she steal them? Just stick them in her purse? It's a small object. It was never explained how she stole them. It's more than possible that, to feel alive, she lifted them with her mind and brought them to her, and a store clerk witnessed her having it outside of the store and caught her (but didn't see her take them). My third reason is the scene in the police station where she is found with tons of cuts all over her face. During her struggle, the power went out, and then came back on. A telekinetic would more than be able to attack oneself with invisible blades and pull a power plug momentarily. Maury may have been lurking around in her mind, had her close the door, shut off the power, and cut up her face. What he wouldn't suspect though is that her son would be there and have an ability even he did not know about to shut off that link (if indeed his own telepathic ability is evolving). This could be why Angela did not die within the Kaito proposed 24 hour deadline.
And about Arthur....he "killed himself." Without Ando there, Kaito would have looked like a suicide, and without anybody in the room with Angela if she died, she would have seemed as such as well. So, it is possible in some way, at least, that if Arthur killed himself with his power, it would, yes, seem like a suicide.
But those are my thoughts.
