Spike (William The Bloody)
Spike, also known as William the bloody, got his nickname by torturing his victims with railed road spikes.Spike got his other nickname as a result of his "bloody awful poetry", and it turns out that he had the name before his vampire days.
Spike killed two slayers, one during the Boxer Rebellion in China in 1990, the other sometime later.
      Angel (Angelus)
Angelus is sired by Darla whom he kills in season to save Buffy. Darla is also the one who brought him the gypsy girl who later curses his soul. Tormented by his soul he breaks away from Darla and eventually end up in New York where Whistler finds him  to show him Buffy. Angel decided to help the Slayer, evertually growing close to her and they begin a romantic relationship  that gives his  tormented life some happiness which lifts the curse. Angelus then returns to his evil ways and begins tormenting Buffy and The Scooby gang. He killed  a few students in this time, but the worst was gypsy Jenny Calendar. Soon Angelus comes up with a way to suck up all the whole world into Hell be using the demon Acatha. Angel's blood is the key to open the portal , so the only way to save the world is to kill Angel
. Buffy finally gets the courage to kill him  just as Willow is able to perfect the curse and Angel's soul back to him.In much regret she sends him to Hell. A few months later Angel returned to earth, and they eventually got back together. Eventually Angel sees that staying in Sunnydale wouldn't let Buffy move on with her life ,so he leaves and goes to  Los Angeles where he, Cordelia and Weasley have a protection agency and he tries to make amends on for all that he has committed.

              Drusilla
Drusilla was made into a vampire by Angel who killed her family, driving her mad. He then made her into what she is today. She is quite an insane vampire as she often worries and has visions of things that about to occur (premonitions). She was restored to full power by the help of her male counter-part  Spike, and
became a major part of Angel's plan to rid the earth of all  humanity (Acathla) as she
and Spike also tried by bringing the Judge to Sunnydale, who Buffy destroyed with a rocket launcher. She killed the Slayer Kendra, by slitting her throat on a raid that put Willow in the hospital, captured Giles, and gave Xander a broken hand. She was knocked out by Spike in "Becoming Part 2) and taken with him to where ever they went. She always had feelings for Angel, and that was potrayed often which made Spike jealous and helpless when he was in the wheel chair. She is beleived to have left Spike.
               The Master

First we've got the Master. He's the grand daddy of all the vampires. He's the most powerful ,strongest and oldest one. His age is shown in his features. His bat like features are the symbol of him evolving from bats. Much like we humans evolved from monkeys.
Sixty years ago he tried to open the Hellmouth to create Hell on earth but was trapped by an earthquake. His firts attampt to free himslef was in The Harvest. In "Prophecy Girl" it was written in the Codex, a book where everything that is prophecised comes to pass, that The Master would kill Buffy and rise. This did, in a way, come ture. She went into the Hellmouth to fight the Master. He bit her and and left her to drown in a puddle while he roamed free. Xander and Angel showed up and Xander gace CPR to Buffy and saved her life. She did die, but only for a split second. The Master did enjoy one moment of being free while Buffy was dead but she came back and killed him by sendinghim back through a window and onto a broken piece of wood.
