No, vampires and Angels are two completely different things.
Hybrid
Angel Investigations The vampire clan from which Angel comes is known as the "Order of Aurelius." It includes the Master, Darla, Angel, Drusilla, and Spike.
They are called "halfbreeds"
Nahuel
Yes. Nonexistent. This isn't Twilight. Jeez.
It was Angel, a spin-off of Buffy, The Vampire Slayer.
Make one up, there is no such beast in myth or lore.
Sanguini
No, she is a half vampire and half human...
Yes she does! Her name is Renesmee and she is half vampire, half human.
The main character of Angel is, of course, Angel. The vampire with a soul. Played by David Boreanaz. It's a spin-off from Buffy the Vampire Slayer.
