5 Heroes Theories

So far the show has provided for many interesting twists and turns as the Heroes are still meeting one another and yet to fully understand their quest, abilities, backgrounds or connections. Many questions and speculations come up. Here's some possible theories I have:

1) Micah, the son of D.L. and Niki has special powers of his own. It seems to be the case if both his parents do.

2) Niki isn't a hero, but was rather created in a laboratory as a murdering device for those trying to take out the heroes. Also possible that there were others created such as Sylar.

3) Isaak's ex-girlfriend, Simone Deveaux is also a villain similar to the girl who connived Mohinder and is leaking the info he finds to Claire's "evil" agent father. One or both of these women may have special powers.

4) Sylar is really Claire's father (or the same guy as her adoptive father). His style of murder is to freeze his victim and chop off their heads. Is this the only way in which a hero can be killed? Or is this to study them somehow?

5) An obvious one, but Mohinder Suresh must also be considered one of the Heroes. His power thus far is unknown, but possibly it is mind-manipulation or telekinesis.
