Claire can spontaneously regenerate any tissue in her body, allowing her to recover from almost any injury within seconds to minutes — though she does need larger objects, embedded foreign objects (such as a branch or a shard of glass) to be manually removed from her body, or bones pushed back into position for the wounds to heal properly. Although Sylar, after studying and taking her power, remarks that he wouldn't be able to kill her even if he wanted to and that she will never die, writers Joe Pokaski and Aron Coleite have confirmed that methods such as decapitation or incineration would indeed kill her. On the other hand, she has survived nuclear explosions in "Company Man" and "I Am Become Death".
