What are the consequences that Claire faces with her regenerating powers?

i don't think her cells will wear out or anything from regeneration though im not sure if she will live forever...

I think she can only be killed by damaging her brain like syler does to his victims. But other than that claire cant be killed and she is immortal just like takezo kensei. remember kensei is adam and he is 400 years old so we can guess that claire has the same ability of immortality.

Hi mdhyat. I did also wonder about Claire's super powers which is her ability to regenerate herself. I wondered how she can ever be killed with that kind of power. That is why I intend to watch the series further. And your question about how Sylar would kill her during the episode of which points to the often quoted "save the cheerleader, save the world". Sylar is known to kill by cutting open the head or forehead. I don't really know if Claire can actually be killed that way.
