Bella Swan (Cullen) vs Buffy The Vampire Slayer
My argument: Pretty much, if you seen and read my Edward vs Blade thread its pretty much the same. Except for the mind reading.
Need to know: Bella's gift allows her to shield herself and those around her from supernatural powers that affect the mind (such as Edward's and Aro's telepathy, Jane's illusionary pain, Alec's sensory paralysis, Eleazar's ability identification, Kate's electric shock, and Zafrina's illusion), which explains why most of their powers were useless against her when she was still human. She had displayed this power since before the beginning of the Twilight series, and by becoming a vampire, her shield was greatly intensified in strength. It has been speculated in the first three novels about what her gift might be after she was changed. This power comes from her subconscious desire to protect her mind above everything else, and as long as she holds on to that desire, it makes the shield difficult to extract. Her father Charlie shows a less developed form of this shield; indeed, Edward finds him difficult to read, but not completely closed off like Bella.
There. Now what?
