Coop Halliwell's History
Coop Halliwell is a Cupid, who is also known as a Messenger of Love. He is the husband of Charmed One Phoebe Halliwell and the father of their three children; P.J., Parker and Peyton Halliwell.
Coop is the only Cupid agent who is also a father. His powers include Beaming, which allows him to teleport himself and others anywhere in the world, the ability to feel love (which is his specialty), slow time, make a person realize their true feelings, and Immortality. Furthermore, Coop has a ring, which provides him with a vast array of other magical powers.
First Life:
Coop was born a little over two centuries ago. He died in his mother's arms shortly after he was born.
A short while after he died, his soul was brought to Cupid's Temple by a Cupid Agent, and he was reborn as a cherub. Once he became a full-fledged Cupid, he was never allowed to visit his family for his protection.
Coop had a mentor and friend Dafydd who taught him to be Cupid. Unfortunately, later he had to inform on him and contribute to his exile when Dafydd went down the path of Personal Gain and tried to get a mortal woman.
Helping Phoebe Halliwell:
Coop first came to Phoebe as a neighbor looking to find his apartment in 2006. Phoebe did not trust him and suspected him of being a demon. Later that day, she broke into his apartment hoping to confirm her suspicion. However, Coop was waiting for her and explained to her that he was sent by the Elders to help her repair her love life, as she had lost interest having given it up so many times for the greater good.
Phoebe was offended by this, irritated that the Elders would think she needed help to find love, but Coop knew that she was just scared because of all her previous heartbreaks and disappointments and reassured her that her future daughter was destined.
To get her to open up her heart to the possibility of love again, Coop gave her advice, and took her to the past to see her past loves—Cole Turner, Jason Dean, Drake dè Mon, Dex Lawson, even her past life P. Russell's warlock lover Anton—so that she could trust love again and see all of the happiness it brings.
Falling in Love with Phoebe:
Phoebe quickly grew to trust Coop and sought his advice on both magical and family matters and over time, the two began to develop feelings for each other. Coop fell first but continued setting Phoebe up with other men to make her happy. However, Phoebe vetoed all of his matches as she was falling in love with him.
Knowing that it was forbidden for Cupids to have a relationship/marry their charges, Phoebe and Coop both decided to hide their feelings from each other to save themselves from the trauma that her sister Piper and her husband Leo went through. However, during one of their disagreements, Phoebe told him it was him that she wanted and the two finally shared a kiss.
Even though they both believed that their love was forbidden, Coop insisted that they could have a life together and was willing to fight for them. However, while Phoebe loved him, she was afraid of getting hurt. Coop was hurt, but he stuck by her and continued to support her during magical affairs. Shortly after, Phoebe and Paige were both killed in an explosion. However, a devastated Coop gave Piper his ring so that she could go back in time and save them.
The Elders had made an exception for Phoebe and Coop due to everything they put her through over the years-though this wasn't discovered until it was explained by Wyatt and Chris, her nephews from the future. As Wyatt said to his aunt and uncle, "it wasn't and it will never be a forbidden love." This allowed Phoebe to freely accept her love for Coop, which also enables her to teleport him to her through their shared connection: love.
After the sisters won the battle against the Triad and returned home, Phoebe immediately greeted Coop and the two shared a loving embrace and started a romantic relationship.
Marriage:
After dating for a few months, Coop decided to ask Phoebe to marry him. He took her to Cupid's Temple to propose and she accepted and they were later married by an Angel of Destiny at the newly regained Magic School. Coop then took the Halliwell name. The two bought a house together that they currently live in with their daughter, Prudence Johnna Halliwell.
Coop and Phoebe seem to share a very caring, honest, and supportive relationship. He's always there for her, standing by her side no matter what she decides to do, as well as gives her helpful advice and encourages her to overcome whatever obstacle she might face. Their relationship is so tight that Phoebe confided in Coop all of the traumatic events of her life including her oldest sister's death.
First Wedding Anniversary:
In 2008, Coop took his wife to celebrate their first wedding anniversary at Cupid's Temple. While visiting, Coop tried to calm Phoebe's fears over her friend Mika's relationship with Cal Greene whom she feared she might hurt with her new power. He even called in a favor to find out information about the two, to help Phoebe. He reassures her that he has faith in her and he will stand by her.
Battling Neena's Army:
When Piper, Phoebe, and Paige pull together a plan to stop the first witch Neena from destroying the Grand Design, Coop goes to take his bow and arrow- an artifact that was previously used for spreading the love with arrows - out of storage. While it doesn't have enough power to kill, Coop uses it to weaken the demons with love, allowing the sisters, Leo, the Elders, and the Warren witches to put a stop to Neena and her army.
Meeting his Family:
After enlisting another dead infant to become a cherub, Coop expresses his grief about how he never got to know his family. Phoebe goes investigating and has a premonition of a Senator's daughter marrying a man named Mitchell Coopersmith. Phoebe manipulates things so that the wedding rehearsal dinner is held at Piper's restaurant, Halliwell's. Coop converses with the groom, his distant relative, and uses his cupid ring to help him get over his cold feet. The next day, Phoebe has a premonition of a huge chaotic fight breaking out at the wedding. Phoebe and her sisters sneak into the church to stop the fight, but Coop's fellow Cupid, Kama, advises him not to, explaining that using his powers on his relative is what caused the trouble in the first place, as it has a strange effect on one's own family. Coop then has a talk with the bride who he is not yet related to and uses his powers to set things right. His familial curiosity satisfied, Coop is happy with having just Phoebe and P.J.
A few months later, Phoebe is informed that she is once again pregnant.
Parker's Birth:
Coop's and Phoebe's second daughter, Parker Halliwell, is born in the midst of the worldwide crisis where all magical creatures had lost their powers, including his own, and mortals gained them instead. Coop is with Phoebe during birth.
When situations turn to the worse, Coop and the others take shelter at Knox Academy: an institution of magic. He meets up with Phoebe and Parker in an alley during the midst of battles triggered by gangs of magic-users. They manage to get to the shelter in one piece.
Like the rest of his family and their allies, Coop participates in their battle against the Darklighter, Rennek, who has taken control over the world's magic. To aid them in battle, Coop uses a bow installing magical properties to fight the enemy. After their side gained victory and balance restored to the world, Coop has his powers returned.
Cole's Sacrifice:
While battling Valen's army of undead, Coop nearly gets killed by the Ancient Athame, which would have enough power to destroy his soul. Cole Turner, knowing the pain it would cause Phoebe if he died, sacrifices himself. After she was informed about Cole's death, Prue gives Coop the fragmented soul of Benjamin Turner, Cole's late father, and persuades him to finish what he started: revive his father.
After months of waiting, Coop joins forces with Henry and Tyler to retrieve Benjamin's other half-soul located in the Demonic Wasteland. Though they succeed in claiming the soul, the vanquished demons begin to give chase, causing Coop to drop the fragments and get possessed by Benjamin. They eventually return home, with Prue's help to extract Benjamin's soul from Coop's body.
Retribution:
This act causes Coop to be called to the Court of Love, where he is judged for going out of his way and neglecting his duty as a cupid. The court decides to separate him from his family, where they are only allowed to reunite once per year on his wedding anniversary with Phoebe and their daughters. Phoebe wants to defy their decree, but Coop explains that if they do not comply, the court will strip his and their daughters' powers, which will make him not only mortal but rapidly age until he dies. With this fact, they are forced to comply. Even so, Coop didn't plan on staying away but promised Phoebe to find a way to fight the decree until they were allowed to be reunited again.
However, it was later revealed that the court and the Tribunal were merely planning to experiment on Coop and anyone who came in contact with Prue's magic in hopes of finding a way to stop the advent. After Prue merged with Heremus, she massacres the Tribunal and kidnaps Coop, intending to use him, Kyra, Ben, and Tyler as sacrifices to bring back the Old Ones.
He is eventually rescued by and reunited with his family.
Later life:
Coop and his wife receive a third daughter the following year, and they named her Peyton Halliwell. He continued his work as a Cupid while helping Piper and Leo set up a council for witches, intending to unite the Wiccan species and help them control their own destiny rather than be controlled by superior beings.
