The Tall Man
Oral tradition tales of a giant whose body served as a portal to other dimensions. Because he was imprisoned centuries ago, nobody knows what this demon's name is or if he even exists.
Matthew Tate
This warlock lived in the 17th century, and had the ability to copy a witch's power when it was used against him. He posed as the lover of Melinda Warren, in order to get her powers. Once he had copied her powers, he betrayed her by exposing her true identity by the Salem witchhunters.
'And because the warlock had stolen her love, she cursed him into the pewter heart, where he could spend eternity knowing the sting of betrayal.'
A locket, which no one but a Warren witch could open.
Tempus
The Devil's Sorcerer. Tempus can manipulate time anyway he chooses. To vanquish him, take him out of the time that he's in.
Tracer Demons
These lower level demons are prized as mercanaries in the underworld for their ability to follow magical prey across different dimensions. Powerful and cunning, they are tricky and impossible to escape.
Three-Eyed Warlock
Warlocks who have a third eye located in the middle of their foreheads. Because the small eye is usually hidden, they can appear as normal persons. The eye emits a deadly laser, which the warlocks use to burn a hole in their victim's forehead and kill them.
The Triad
The Triad is a group of demons who are at the highest level of the evil side. They're responsible for organizing attacks on specific individuals. They usually assign demons of a lower level to do the job for them.
Trok Demon
A monstrous two-headed demon who generates violent blasts with his roars. He can only be summoned while on an earthly plane.
Troxa
This invisible demon has the ability to attack unsuspecting victims and escape without detection.Although his power prevents the naked eye from seeing him, his being is still corporeal, therefore he cannot pass through objects or walls.
Troxa's one weakness is that his ectoplasmic biochemistry is sensitive to cold. When the temperature lowers, he may become partially visible.
Tuatha
Two hundreds years ago, a good witch turned evil, and started using her craft against innocents. Fortunately she was tricked in a cave and entombed.
Tuatha kills good witches, and if she is reunited with her magic wand, she becomes impossible to vanquish.
The only person able to defeat Tuatha, is the Chosen One; the seventh son of the seventh son. He is born to use Tuatha's wand against her.
Vampires
Special demons who, in order to survive, must hunt people down and drain their blood using their long canine teeth.
Vampires can turn into a bat at will, and are immune to witch's powers.
Vampires are ruled by a Vampire Queen. Kill her, and all her 'children' die with her.
When a person is bitten by a vampire (either in bat or in human form), he or she will become one as well. Though the real transformation into a vampire only takes place once blood is spilled ("or in this case sucked" -Piper). Therefore, (if the person hasn't bitten anyone yet of course), the person can unbecome a vampire by killing the Vampire Queen.
Because the vampires had a conflict with The Source, they have been exiled from the Underworld for many years.
Vinceres
Vinceres is a demonic assasin, timeless and unstoppable. He will never give up until he kills his target and he is immune to a witch's powers.
Vulture Demons
These vicious demons feed on the remains of dead demons and other helpless prey with their sharp teeth.
