David Boreanaz
The loss of "Angel" (David Boreanaz) on "Buffy The Vampire Slayer" was difficult for fans to cope with. Shortly before his demise, he confessed his love to "Buffy" (Sarah Michelle Gellar). With a heavy heart, he had to ram a sword in his chest to eliminate the evil. "Angel" was missed so much by his fans, that he got his own spin-off series.
