Honestly, I think you could name ten Heroes characters that aren't related. Uh, okay- Peter, Noah, Matt, Mohinder, DL, Niki, Simone, Sylar, Hiro, Edgar. See? Others: Elle, Linderman, Thompson, Claude, Luke, Sandra, Ando, Molly, and more.

That's a toss-up there, I'd say. Depends on what point in canon you're choosing.
