Cordelia Chase

When Buffy arrives at Sunnydale High; she is greeted by popular girl Cordelia, but the two soon grow apart, especially after Buffy accidently attacks Cordy with a stake. Cordelia then decides she is crazy and will have nothing to do with her. Yet when strange things happen to her, she always turns to the gang for help, eventually even becoming on of the Scoobies when she starts dating Xander.
Part of the cheerleading squad, tactless and extra bitchy, Cordelia leaves Sunnydale, hoping to become an actress in L.A. But the occult soon catches up with her and she joins Angel in his fight against evil.
In L.A., she changes a lot, becoming a much better person. She inherits the power of visions and starts to fall for Angel.
