Darla was Angel's sire. She was about 200 years old when she met Angel in Galway, Ireland in 1753. They were together for many years until Darla gave Angel a gypsy girl to feed on. That girl's tribe put a curse on Angel which restored his human soul. Darla could not accept him so she threw him onto the streets. Darla became a member of the Order of Aurelius and was the Master's favourite for around 400 years. When Angel killed Darla The Master was devastated. But if you have all been watching Angel, in the season finale we see that Wolfram and Hart have brought forth none other than Darla. Darla came and went to LA, after trying and being unsuccessful to remove Angel's soul, Darla has presumably left LA. She went to Puerto Cabazas, Nicaragua in a bar is the next time we see her, pregnant.

Elizabeth was one of Angelus' old drinking buddies from the day. She re-appeared in LA while Angle was out on a routing vampire hunt. She was among the vampires being hunted and Angel killed her without realising who she was. Later on he found out, because of the locket she was wearing at the time. She was at least 234 years old. James, her loved sought after Angel for revenge.

Ernesto

Ernesto is the bodyguard and maybe a bit of a campaign manager for Senator Buckner. A demon inhabiting a human's body, who's bid it is to get to Washington.

James is from Angelus' past. They were mutual friends. He and his lover Elizabeth and Angelus and Darla hung around together. Back to the future Angel unknowingly killed Elizabeth. James sought revenge for killing the girl he loved. James got his heart removed by a Dr. Gregson and so was invincible for 6 hours. He fought Angel, but unfortunately time ran out and he died.

Marcus was a vampire, a torturer. He tortured anything, it was his art. He liked children, he like to eat children. He was hired by Spike to torture Angel until Angel gave Spike the whereabouts of the Gem of Amarra. Spike thought Marcus didn't care about the gem, but he was wrong (again) and Marcus went with the gem. Angel went to fight Marcus, and even with the ring on he was totally un-killable. With a piece of wood through the heart, Angel took the ring off Marcus and Marcus turned to dust.

Penn was a vampire who was sired by Angelus in the late 1700's. Penn killed his entire family. Angelus was the best teacher, he turned Penn into a homicidal maniac, killing freely. All is kills were based on his first day as a vampire, killing his family. In Los Angeles he was trying to reenact the same thing. But with Angel on the case it wasn't going to happen, and Kate. In a showdown with Penn and Angel, Kate killed Penn by staking him and Angel, but with Angel it wasn't through the heart.

Doug Sanders as a vampire holds a promote the vampires kinda seminars. Helps vampires to become the best they can be. He gets kind of a cult following. He has a pyramid theory. If one vampire makes two people, then one of those will make another and etc and etc the vampires have themselves a neat little army. The A-Team found out about this from one of Cordelia's visions. Harmony was sent in as an undercover vampire, but ended up getting sucked into the scheme too. The A-Team then fought the whole lot of them, and freed the people that were held hostage there. Angel killed Doug by decapitation by an axe.

 His name, Spike he got from his killing technique, he killed people with rail road spikes. Spike went to Los Angeles in search for the Gem of Amarra. But he found Angel. He hired Marcus to torture the location of the ring out of him. But it didn't work, Angel was saved in time. Marcus ran off with the ring and Spike was left with nothing.

This was the vampire that Darla was trying so hard to convince him to sire her, when she found out she was dying. He was made in 1992, so a comparably young vampire. Had no previous experience of the concept of siring a person. Seemed fairly geekish. Just as he was about to feed off Darla Angel kills him with a stake through the heart.

Russell was a businessman and a vampire. He preyed on young girls looking for fame and fortune, without any family or friends. He loved anything to do with pain and death. When Russell gets hungry he just picks anyone of those helpless girls and eats them. One of them was Cordelia. Luckily enough Angel knew what he was, and was there. Russell and Angel fought, but Angel was driven off by gun shots. He did save Cordelia. Knowing that Russell would go after Cordelia Angel decided to make the first move. He pushed Russell out of the window of his office in daylight. Russell burnt up before he reached the ground.
