How Sarah Michelle Gellar's beloved character Buffy Summers became the slayer is one of the biggest questions of the popular TV show Buffy The Vampire Slayer. The show aired for six seasons from 1997 to 2003 and told an always exciting and entertaining story about a teenage girl caught between two worlds. On the one hand, Buffy loves the strength that she finds through her responsibilities of fighting demons and saving Sunnydale, California from evil. On the other hand, sometimes she just wants to be normal.
