Heroes - Yu Yu hakusho connection

Well it may seem odd but there are a couple of things that make me think that Tim Kring may have in some way been influenced by Yu Yu Hakusho. The first being that Niki's disorder plays out a lot like Sensui's (the fracturing of thier psychosis and whatnot) I know that could just be a coincedence so for now we will just have to wait and see what happens. As for the second of the reasons: Bob had asked his daughter Elle if she had been praticing her sharp-shooting skills when she responded with a familiar looking "spirit gun" poised finger that shot out electricity, which of course looks a lot like ki. Niether of these points are too terribly convincing but I really just wanted to get this out there and see what you all think.
