A detailed description of who the slayers where! This is my description, and completely original! Approval needed for other usage

Buffy Anne Summers
Entered : Season One
Episode : One
Description : Buffy is the first slayer introduced to the views of btvs. She was called at the tender age of 15, whilst sitting on the steps of the L.A high school known as Hembry.
Buffy learnt quickly how to deal with the ups and downs of her so-called-slayer-life and was kicked out of hembry after burning down the gym. Since then she has died twice. Once by default, and drowning after the marster drank from her, the second time was to save her sisters life, by offering hers. Both times she has been brought back to life by her friends.
Her first death brought on the activation of the second slayer kendra ......

Kendra
Entered : Season Two
Episode : Whats My Line - Part 1
Description : Was called after Buffy drowned and sent to Sunnydale by her watcher, who believed that some deep dark evil is rising, in which she needs to stop.
Obviously this was a mistake, but Buffy was physically dead, and therefore activating the next slayer, but Buffy and Kendra had a lot of tension and difficulty between them both, which was finally worked out 2 episodes later.
Kendra makes another appearance later on down the track, when Angel is about to send the whole world into hell. Unfortunately Drusilla kills kendra, therefore activating the next slayers call, which is Faith......

Faith
Entered : Season Three
Episode : Faith Hope & Tricks
Description : Was called when Kendra died, and was a little bit on the rebel side of things. She of course was from the down town, back street kinda girl, and didn't have the same kinda of childhood that Buffy did, so she did things in a different manner.
Buffy and Faith pretty much hit it off well, and fought alongside each other for some time, until Faith went a little to far and killed a man, blaming it on Buffy. After this she turned to the dark side of things, and started working for the Mayor.
In the finale of season 3 *graduation* Buffy put Faith in a coma in part 1, therefore taking her out of the running for the ascention.. She later woke up in Season 4, and took over Buffy's body for some time, until escaping in her own to LA
At the moment Faith remains in Jail, where she was placed after giving herself up in an Angel episode

1st Slayer
Entered : Season Four
Episode : Finale - Restless
Description : She has no name, but she was the first. There is not much writen about this slayer in any books, and not much is known in history..
She appears in the scooby gang's sleep, and finally speaks to Buffy, trying to tell her of what a true slayer is, and how she should act.
Throughout the season 5 she makes guest appearance guiding Buffy, and telling her what she really is.. and how Death is her Gift
