In the End, Some other Greatest Pains, Become your Greatest Strengths."
This quote reminds me of Buffy. It shows about how grow up and live her pain over seven years. Thats what made her "Powerful Slayer". Just like Faith, Spike and Angel.
When Buffy Summers first came to Sunnydale, she was newbie slayer. She was chosen to be the only slayer in Sunnydale. Something that she has to accept through Giles and Scoobies. Buffy was beginning to learn her power through the first year of High School. Experiencing True Love with a vampire with a soul "Angel". When Buffy was about to defeat "The Master", she learned from Giles that the Prophecy said once a Slayer affronted the Master she will die. Buffy cheated that Prophecy, and made choice to become death itself.
After the first year of slaying and high school. She was back with totally atitude adjustment. Once she finally got her rocks off with destroying the remains of "The Master" she saved Sunnydale from The Hellmouth. But there was a new vampire cult that wants to destory the world. Spike & Drusilla the two legendary vampires of the Fanged four that new Angel and Darla. Buffy knew that she must face Spike and Drusilla, but she figured that Drusilla was little obsession of Angel's past. Even though Angel sired her and killed her whole family. Buffy's feelings for Angel was in fire, she and Angel had experienced "The Moment of Pure True Happiness" together. Angel lost his soul and reunited with his fanged gang with Spike & Drusilla. Buffy knew that soon one day she confronted her lover and with a little a faith Willow got Angel's back through dark magics. He was back as Angel, once the portal opned Buffy made a choice and sacrifice her lover in order to save Sunnydale and the rest of the World.
Another year for Buffy she experienced Life & Death through Angel. But she was chosen, and Buffy again face Mayor Wilkinson and destroy him. Then Buffy was confronted with Adam in University of Sunnydale, a demonoid, made by a physictic Professor. Buffy had someone else in her life to experience her life. Riley Finn, who knows about Demons and Slayers.Buffy destoryed Adam, and after her battles she was restless,and met the First original Slayer who showed her path of Slayer.
Moments fade away when Buffy met Dracula and told her that her power fall to "DARKNESS". Worries her to much and want Giles to be her watcher once again.Then learned that she has sister that is so special to her and the world. Buffy was chosen to protect Dawn from Glory who want her to open a portal that would open all the demon dimensions in the world that would bring the world to end. Buffy made a choice of sacrificing her life and learning her gift through Dawn.
Resurrected from the dead by her friends. Saying that she was ripped out of heaven by her friends. Feeling disorented that feels this is hell for her. She told this Spike and he gave her meaning to live. Buffy was feeling something dark and unsupernatural towards Spike that want her closer to Spike and feel alive through him. Buffy started a uncontroling relationship that was so not healthy for a Slayer and a Vampire to go through in life. Buffy forgeting her calling as a slayer, and Spike's calling as a vampire. Thanks to Riley Finn to open their eyes.
After moments dispate through moments rape, sexual violence and calling. Buffy was back with her calling as a chosen Slayer. She confronted an old enemy name "The First" that gave her an opportuntiy to lead an army of potential slayers into a first war of their lives, to risk anything in the name of "Destiny". Buffy was chosen to be the Guradian of The First evil. Once she has a vampire soul A.K.A Spike who was the best warrior she got on her side. He gave her confidence, strength and a meaning of Leadership.
Buffy was making better choices to have someone else to take over her to save the world this time and that was Spike her true champion.
