Cole Turner was born in 1885 to California state assemblyman Benjamin Coleridge Turner and a demon mother named Elizabeth. Benjamin was murdered in 1888 by Elizabeth, who then took Cole from Earth and raised him in a demon dimension. Cole's demonic side grew up despising his human side for its "weakness", and he became a powerful demon with a reputation as a killer under the name Belthazor. In reality, his human half is an incredibly caring and good person, which makes the suppression of his humanity by his demonic half all the more horrible and evil, also later when Cole is possessed by the Source, his human half is repressed and corrupted.
Cole became a member of the Brotherhood of the Thorn, who served the Source of All Evil. He made a reputation for himself as an assassin who could kill any witch, an athame being his weapon of choice. Cole was hired by the Triad to get close to and kill the Charmed Ones. To do so, Cole returned to Earth in his human guise and was set up as an assistant district attorney in San Francisco.
After much pressure by the Triad to finish the job, Belthazor finally employs the spirit of Rage, Andras, to assist him. Andras infects the sisters with rage, causing them to turn on each other, severing the Power of Three. Despite his victory, Cole cannot bring himself to kill Phoebe, and he is exposed as a traitor. Andras possesses Cole, and he is forced to try to destroy the sisters. The sisters manage to regain their powers just in time and successfully fend off Belthazor. Belthazor vanquishes Andras, but is wounded by the Charmed Ones, who are able to create a vanquishing potion from Belthazor's flesh. At this point, the Triad attempts to execute Cole for treason. Cole turns on them, supposedly killing them in the process before fleeing back to his apartment to recuperate.
When Phoebe goes to see Cole at his apartment, she finds that Cole is wounded and calls Leo to heal him. Leo tries to heal him but realizes that something is terribly wrong when he finds that he can't heal all of Cole (leading Leo to suspect that Cole is demonic, which Leo then warns Phoebe about).
When Prue and Piper, who are working with a demonic bounty hunter, break in to Cole's apartment, Cole grabs Phoebe and shimmers to the mausoleum, proclaiming his love for her, explaining that he was born half human (Cole) and half demon (Belthazor), and that she has awakened his humanity. She initially does not believe him, but when he is wounded by the bounty hunter, she decides to defend him. She battles the bounty hunter, but he gains the upper hand. As the bounty hunter is about to kill her from behind, Cole screams "No!" and kills the bounty hunter with an energy ball. He asks Phoebe, "Now do you believe me?" Phoebe fakes Cole's death, to keep him from being killed by other demons or her sisters, and tells him to run.
Phoebe and Cole once again grew close as he helps free her from a psychic link with a Native American who was cursed into a time loop. Cole returns and becomes the Charmed Ones' demonic ally, working alongside them and helping them just like Leo. He even witnesses Piper and Leo's marriage.
While at Prue's funeral, Cole is attacked by two demon bounty hunters, but quickly kills them. Later on, he discovers that the Source has sent a Chameleon demon named Alastar to spy on the Charmed Ones. Once uncovered, Alastar is attacked by the sisters and flees. The Source kills Alastar and takes his place as the sisters hunt him down. The Source then kidnaps Piper and takes her to the Underworld, where he uses his mental powers to create a fantasy world wherein Piper is a mental patient, hoping to trick her into giving up her powers to him. Cole and Leo travel to the Underworld to track down Piper while Phoebe and Paige use a spell to project themselves into Piper's mind. As Piper is nearly ready to relinquish her powers, Cole attacks the Source repeatedly with energy balls as he stands immobile, controlling Piper's mind. Cole is eventually able to wound the Source, but as he attempts to kill the Source his attack is blocked by the Source's Oracle, who dies so the Source can escape.
Some time later, the sisters become aware of a demon who is killing witches. After Piper scries for the demon from slime they find, Phoebe and Cole attempt to track the demon down. They are attacked by a Scavenger demon, which is feeding on the remains left by the killer. It is at this time that Cole asks Phoebe to marry him in a spur of the moment. When Cole has to embrace his demon side in order to defeat another demon, a potion is used on him to vanquish his demonic half, leaving only his human half alive.
Shortly after Cole becomes human, Cole and Phoebe are possessed by the spirits of Frankie and Lulu, a criminal couple who find their way to the present through a time portal. They go on a crime spree, stealing a diamond ring and a wedding dress, all so they can get married. At the church, Cole is shot and Frankie's spirit escapes, only to be captured by a spirit named Clyde and sent back in time through the time portal. Then Phoebe accepts Cole's marriage proposal.
Later, the Seer betrays the Source by contacting Cole and giving him the Hollow to help defeat the Source. She convinces him to do this by insisting it is the only way to save Phoebe's life. When The Source throws a fireball at Phoebe, Cole dives in front of it and absorbs the Source's power. The sisters vanquish him in his powerless state, then the Seer and Phoebe say the spell together to put the Hollow back in its crypt and Piper and Paige's stolen powers were restored. When the Seer says the Source's power went "into the void", she was referring to the "void" where Cole's demon half used to be. Cole had permanently absorbed the Source and the Source's power, which was the Seer's intention.
Now fully controlled by the Source, Cole orchestrates a number of events to spur Phoebe to call off her wedding, in order to marry Phoebe in a demonic ceremony (which is disguised as a private ceremony). Shortly after, Paige begins to distrust Cole. Cole hires a power broker to imbue Paige with a demonic power in order to distract her and her sisters so he can impregnate Phoebe with his evil spawn. Once alone with Paige in the manor, Cole plays mind games with her, nearly driving her insane, save for her sisters' intervention. At the last moment Cole gains enough control from The Source to save Paige by having other power brokers take the power out of her.
When a power struggle breaks out between Cole and the exiled Vampires, the Vampire Queen sends a group of vampires to bite Paige and make her a vampire under her thrall. Although they are successful, Cole is able to kill the Vampire Queen before Paige is fully converted into a vampire.
Phoebe indeed becomes pregnant (she doesn't know that her child is a child of the Source, and contains nothing of either Cole or herself) and she begins throwing fire and teleporting because of her baby's demonic influence. When Cole tries to convince Phoebe she is not turning evil, she finally gets a premonition revealing Cole is a demon, and she immediately leaves him.
Cole's love is now strongly affecting the Source, and Cole refuses to be confirmed as the Source; The Seer then goes to try to convince Phoebe to go back to Cole. When Cole is attacked by an evil wizard who schemes to seize the Source's powers, Cole offers to give up his position as the Source, and to transfer the Source voluntarily into the Wizard, as a final attempt to rid himself of evil power and win Phoebe back.
However, during the transfer ceremony, the Seer makes Phoebe believe that the wizard is in fact killing Cole. With the Seer's coaching, Phoebe uses her baby's powers and kills the wizard before the power transfer can be complete, nullifying Cole's final effort to become good again. Phoebe then joins Cole as his Queen, and the couple become the new rulers of the Underworld. After some mishaps; namely her killing off many upper-level demons, saving innocents and being tricked by the seer, Phoebe begins to doubt her role as the Queen of the Underworld. With Phoebe's loyalties torn between Cole and her sisters, Paige and Piper attack Cole, banking on Phoebe choosing the right side. Phoebe is forced to side with her sisters and vanquishes Cole and the Source's power with him.
After being vanquished, Cole and the Source finally end up as separate beings in the astral plane of the demonic wasteland (where demons usually go after being vanquished). The powers of the Source, however, were inherently duplicated/embodied in the demonic child and heir of the Source. With Cole gone, the Seer was free to steal the demon spawn from Phoebe's womb and seize power as the new Source, which was her plan since the previous incarnation of the Source summoned the Hollow. Subsequently, the Seer was overwhelmed by the Source's power, just as Phoebe was, and the sisters turned that to their advantage, causing the Seer to explode and vanquish the entire demonic court.
As Cole was born a half-human (Cole)/ half-demon (the now vanquished Belthazor) being, Cole has a human soul, whereas pure blood demons have no souls. This is "rather unique to the cosmos," as Cole puts it. Cole has no inherent demonic powers in the demonic wasteland, as he was fully human when he was possessed by the Source (after the Source's previous body was vanquished).
Cole quickly gains massive demonic powers and seeks redemption again. He comes back briefly to save Phoebe from a bullet, by switching her position with that of the witch hunter, who had just fired a bullet at Phoebe's heart. He tells her that he isn't giving up on them.
However, Phoebe and her sisters aren't about to accept him anymore. He comes back just as Phoebe is about to get a divorce, and she tells him it is over.
Later, Cole talks to Darryl who convinces him that if he loves Phoebe, he should go away, and he finally agrees. However, Paige intervenes thinking Cole might be able to save Phoebe, who was heartbroken and wanted to become a mermaid because in the charmed universe they do not feel emotions. He disagrees with Paige but she casts a spell to show him how much Phoebe loves him. He goes to save her, and helps her turn back from a mermaid. Although she says that she still loves him, Phoebe explains that their relationship is too hopeless to fight for anymore.
He tries to prove that he is still good so that Phoebe will take him back. He saves a future Whitelighter from a fire and is hailed as a hero, by all but Phoebe. Again and again he does good deeds only to be rejected each time by Phoebe, on the grounds that his powers and his nature are evil and that it would only be a matter of time before that nature betrayed her, and by proxy, his goals. Her fears are justified when he is seduced, kissed and momentarily killed by a siren, but he then revives. Phoebe had arrived at the scene and was about to vanquish the siren when Cole, overcome by the very evil she warned him about, destroys the vanquishing potion. He kisses the siren, and turns against Phoebe, strangling her to near death.
After being alone for many months, Cole gradually goes insane, due to the countless demonic powers he has taken into himself from the demonic wasteland and his despair over Phoebe's continued rejection of his love, no matter what good deeds he does. When he concludes he can not be good and he will not be evil, he decides to end his life. He believes that the Power of Three is what is necessary to kill him again. He provokes the sisters into attacking him (death by cop), but their best shot proved unable to kill him, much to his chagrin.
Cole is now unvanquishable by any power, including the Power of Three's (part of why the Avatars of Force and Power wish him to join their collective power). Cole then tries to kill himself over and over, even trying to behead himself, only stopped momentarily by Piper freezing the blade that was about to sever his head from his body (that would not have killed him either).
Having gone completely mad, Cole's obsession for Phoebe consumes him. He vows to get Phoebe back, no matter what it takes. He even teams up with demons to help him in his schemes, but with every mad attempt, he fails. Which includes trying to take the Nexus from the Charmed Ones to turn Phoebe evil again (which failed and almost killed him).
Paige catches a cold from being thrown in the icy waters of San Francisco, after she again tried to vanquish Cole, and every time she sneezes, she orbs into a neutral void, outside of space and time, where beings like the Avatars live.
Cole believes Paige was the reason Phoebe gave up on him, so he creates an parallel alternate universe or alternative reality (even though he was warned by the Avatar leader Alpha: "You have no idea what you're getting into. Changing the past to create an alternate reality has unforseen consequences, Cole. Even for you...".), with the result being (whether originally intended or not), that the alternate Paige was killed by the alternate Source, and the alternate Piper and Phoebe have never known that they had a half-sister...
At the exact moment that Cole's spell creates the alternative reality and transports Cole there (also apparently the timeline there is slightly different, so Cole's birthday is just starting, rather than ending), Paige sneezes, orbs and is also transported into the alternative reality.
Paige calls for Leo, and with his help tracks down this reality's Piper, and tries to try to convince them who she is. Paige believes that the primary reality was changed (It is not until she is back in her original reality, that she realizes that it was in fact unchanged by Cole's spell, and states in surprise, "Time must have continued moving on in this reality too" and "He straddled two worlds, just like I did...").
The Avatar leader Alpha appears, and warns Cole that his spell is foolish, that Cole has displaced and assumed the place of the alternate dual Cole/Belthazor being, and while he has all the powers that Belthazor had, he also can die in this alternate reality, just like Belthazor could.
Cole: "What are you doing here? I thought I was the only one to cross over".
Alpha: "That won't be your last miscalculation, I'm afraid. Avatars exist outside of time and space. That's why I'm immune to your spell... A spell which I beg you to reverse, before it's too late...".
Cole: "Too late for what"?
Alpha: "For you to die... You're not invincible in this reality, Cole. By changing that one critical event, you've changed even more than you see before you... You've changed you".
Alpha pleads with Cole to undo his spell, and promises Cole a future if he does, but Cole says that he can't, that he has to play this out.
In this alternate reality, the Power of Three was never restored, Belthazor was never vanquished (leaving the human Cole), Cole is married to Phoebe, and is again living in the manor. It also becomes clear that the alternate Cole/Belthazor being that Cole displaced, had become completely controlled by Belthazor.
Cole has a brief moment of feeling happy, when he enters the manor and sees a huge pool table.
When he starts to look for Phoebe, he is caught by surprise by a surprise birthday party and many demons appearing, cheering him, and calling for him to make a speech. He is also surprised by the appearance of the Seer, and he is clearly trying to figure out what role he has to play, at least for the moment.
When Phoebe appears, he is again surprised...
Phoebe: "What's the matter? Not what you expected"?
Cole (lovingly): "No, you look, you look, great, really"!
Phoebe: "Did you just give me a compliment"?
Cole: "You have no idea, how happy I am to see you"!
(Cole leans in to kiss her on the lips but Phoebe turns her head and he kisses her cheek instead. She pushes him away.)
Phoebe: "What the hell is the matter with you"?
(Phoebe pushes past him and walks away.)
When the Seer states to Cole that her visions have not changed, that once Phoebe conceives his magical heir, he won't need to keep up pretenses, as The Seer will take it from there, Cole simply freezes in horror, while the Seer starts stroking his face. This distracts him from noting Paige entering the manor, and following Phoebe.
Phoebe clearly doesn't believe what Paige tells her, calls for her guards, and Paige runs out the back door, being chased and shot at by a bespelled Darryl Morris. Leo orbs in and saves Paige at the last moment. Leo, Paige and Piper join forces and discuss what to do.
Piper: "This Cole of yours, must have cast a pretty powerful spell to do all of this. But if we vanquish him, the spell should automatically reverse itself".
Paige: "Fine, except for we've already tried to vanquish him... He's become invincible in our world".
Leo: "Yes, but we're not in your world, you're in ours, so is he. So, if you've assumed our Paige's life, he must've assumed Belthazor's".
Paige: "Yeah, he would've".
Piper: "Did you guys try to vanquish Belthazor ever"?
Paige: "No, but you and Prue almost tried. You guys had a vanquishing potion, right"?
Piper: "How do you know about that"?
Paige: "Book of Shadows. It also says that it needs a piece of his flesh to make it work".
Leo: "That's right, it did".
Piper: "Alright then. Let's go hunting".
Cole catches Phoebe in bed with another demon, whom Cole then very angrily vanquishes. Cole also doesn't turn into Belthazor, not matter how enraged he becomes, thus again showing that he's Cole with powers, rather than being Cole/Belthazor.
When Cole asks Phoebe how they could be so much in love and still have it turn out this way, Phoebe replies, "Maybe, it just wasn't meant to be"?, and walks away. While the alternate Phoebe loved him (just as she did in All Hell Breaks Loose) at the start, she now stays with Cole to try to protect Piper from suffering the same fate as Prue, and she now cheats on Cole left and right.
Then Piper appears (apparently hiding and waiting for Cole - Leo must have orbed her in first) and attacks Cole at the manor in the upstairs hallway; Cole doesn't explode, even when hit in the chest, neck and face with the full force of Piper's powers, but he is thrown through the air, into a cabinet built into the wall, and he falls to the floor stunned and in pain.
Leo orbs Paige in, and right after the dazed, astonished and furious Cole gasps "You"! at Paige, she cuts a piece of flesh from his right hand with a knife, while Cole screams in surprise and agony. Cole face also shows dismay (while looking at his wounded right hand) that his self-healing powers really are gone in this alternate reality.
Phoebe, having heard the smashing of the wall cabinet and Cole's scream of pain, comes running up the hallway, and stops Cole from launching a huge energy ball at Paige, Piper and Leo. Leo shimmers Paige and Piper away, before Cole can attack again.
Cole absolutely panics, knocks Phoebe to the floor, and orders the demons running up the hall to find and kill Phoebe's sisters. Phoebe gasps "Paige was telling the truth"?, and Cole warns her that if he goes down, that she goes down with him (actually, if Cole dies, everyone in the alternate reality ceases to exist along with that reality, except those who are there from the original reality, so this is a fairly literal statement).
Paige makes the original vanquishing potion for Belthazor, which clearly becomes potent once the pice of Cole flesh is tossed in; Paige warns that it still might not work and Paige, Piper and Leo go to the manor.
They encounter Phoebe, who begs them to leave. Cole then appears from behind, throws a huge energy ball at Paige, Piper and Leo - which Leo and Piper take the brunt of - which knocks Paige, Piper and Leo through the air, slams them into a bar (from which drinks were being served earlier), and they collapse on the floor. Leo and Piper are injured and are out cold, Paige is dazed, and Cole telekinetically grabs the vanquishing potion, and it flies into his left hand.
Paige tells Phoebe that Piper is alive, and to grab Piper's hand. When she does, magical energy surrounds the witches, and the Power Of Three is created in the alternate reality, empowering the sisters, and their spells and vanquishing potions, with all the magical power they had in the original reality. Cole fires off an energy ball at Paige, but the energy ball is repelled by the magical energy surrounding the witches, and he has to duck very quickly, or be injured by his own ricocheting energy ball (which breaks out a window behind him).
Paige orbs the potion into her right hand, and starts to throw it at Cole; Phoebe cries out "No"! and grabs the potion from Paige.
Paige: "Phoebe, are you crazy? Throw it before he shimmers out"!
Cole: "She's not gonna throw it..."
(then looking right at Phoebe asks her)
Cole: "Are you"?
Paige (firmly): "Throw the potion".
Cole: "We've been through so much together, haven't we"?
(Phoebe stands looking at Cole, holding the potion)
Cole: "Our love's so strong, nothing can destroy it, not even... this".
(Phoebe still stands looking at Cole, holding the potion)
Cole then says (his voice thick with passion): "We're meant to be together".
Phoebe (changing her mind): "I don't think so".
Phoebe throws the potion. Cole's face looks absolutely terrified as the potion strikes him in the chest, and he bursts into flames.
In spite of themselves, Phoebe's face looks dismayed and Paige visibly winces, while a gasp of pain is heard from Cole.
Cole then screams: "Ohhhhhhhhhhhhhhhhhhhhh, Noooooooooo"!, while the flames rip through his magical defenses and into his flesh and bones. Phoebe blinks back tears, as Cole's body turns into a huge pillar of flames.
Cole again screams in agony, while he explodes into a huge fireball which rocks the manor, and his final scream and what sounds like a clap of thunder echo together, into what sounds like a vast distance; There is nothing left of Cole, but a small amount of flames burning where Cole was standing.
Phoebe's face looks like she can't believe that Cole just died, and she also looks quite miserable (this alternate Phoebe would have no memory of vanquishing Cole before, when he was possessed by the Source, and she has never gone through all the emotions, that the Phoebe in the original reality has already faced).
Then, the alternate reality starts spinning around Paige, Cole's spell is reversed, and Paige finds herself back in her original reality, with the pregnant Piper's approaching her, and asking where has she been?
Cole is vanquished once and for all (or so it seems at the time).
He was killed on his 117th birthday, though at the time the other demons in the alternate reality pretended that he was only 100 years old. To that end, the Seer had even vanquished Cole's demon friend (and cake maker) who joked that he thought Cole was actually 117.
Cole also says that he wants Phoebe not to give up on love and wants her to move on. It is revealed that Cole was the one who arranged for Drake to become human and meet Phoebe, and arranged Piper's attack from the Thorn Demons. How Cole managed to accomplish this remains a mystery. Nor is it clear just what kind of being Cole is now. When Piper asks if he is a Demon, ghost, poltergeist, or spirit, Cole said he is none of those things, but did not specify further. He did, however, say that he is trapped in this realm for all eternity for the evil he has committed. He is last seen thanking Drake for helping Phoebe, and Drake expressing remorse about being unable to help Cole too. Cole replies that he has accepted his fate, and didn't want his fate to be Phoebe's. Drake then dies, his last words being "Farewell, my friend." and rising up towards heaven. Cole then smiles and fades away forever. It is unknown whether Cole is dead or not but with his abilities and influence over the magical universe, Cole may very well be alive but watching over in secret.
Cole eventually becomes The Source of All Evil. Theoretically, he possesses most or likely all of the powers of The Source, including teleportation, fireballs, force fields, lightning bolts, pyrokinesis, shapeshifting, telekinesis, summoning, mind control, and possession.
During his time in the Demonic Wasteland, Cole learns that the serpent of the Wasteland feeds on the powers of vanquished demons. In taking the powers before the serpent is able to, he eventually defeats the serpent, or at least destroys parts of it, making him able to obtain whatever powers are available. Since Cole returns from the Wasteland within 72 hours of Phoebe traveling there, we only see about ten different powers used on screen. The actual number of powers may be as few as ten or well in to the hundreds or thousands, however, the exact number or type of powers is impossible to determine. Cole is seen on screen using teleportation, telekinesis, throwing energy balls, conjuring, lightning bolts, and molecular manipulation. He also has invincibility, the ability to grant it to other demons for a time, and some time control. We can assume that his time-related powers are not vast, as he must go to the Avatars in order to change reality.
As an Avatar, Cole possessed ability to change reality. Given the nature of Avatar powers, however, we can conclude that Cole's powers were virtually unlimited, and included, but were not limited to, energy waves, lightning bolts, power binding, time control, the ability to create illusions, to remove people from existence, resurrection, and teleportation.
However, when he changes reality, including his own physical history, to be with Phoebe, he loses his Avatar powers in addition to his powers from the demonic wasteland. Cole ceases to be physically immortal, and reverts to having only the demonic powers of Belthazor, without actually being the dual Cole/Belthazor human/demonic being. Other demons in the alternate reality are unaware of this, but a reference is made to the Seer about possibly reporting him to the Source, for his "slightly off" behaviors. Cole is therefore rendered vulnerable in the alternate reality to anything that would have harmed or killed Belthazor, which the leader of the Avatars warns him about, in an attempt to get Cole to reverse his reality changing spell.
