9. Claire Bennet (Heroes)
"Save the cheerleader, save the world". Claire's fate was tied to the fate of the Earth so, in essence, she was the Earth's last hope - if she died, the Earth died. This made her, arguably, the most important character throughout the
Heroes saga. This, in turn, makes her a brilliant candidate to wield a Blue Lantern ring. She was also brave and had come through some awful experiences - such as a rape attempt - and proves that there is hope for everyone. The amazing healing powers that Claire had, which rendered her nigh on immortal, would compliment the ring's powers beautifully and make her a formidable Blue Lantern who would be very hard to permanently put down.
