Corey Halliwell is a Whitelighter-Witch and the first child of Piper Halliwell and Leo Wyatt, he is the older brother of Jonah and Maiya Halliwell. He was the oldest child of the Charmed Ones until the discovery of Prue's first and only daughter Melinda Halliwell. Corey along with Jonah and Maiya make up the new Charmed Ones. Corey was the first born male into the Warren/Halliwell line. Out of him and his siblings he always thought of himself as the weakest Charmed One only being able to see the past and future, until some comforting words from his aunt Phoebe he finally stopped thinking he was the weakest link.
Due to a law created by The Elders Corey's parents were not allowed to be romantically interested in each other, but due to the Charmed Ones saving all the Whitelighters and Elders from a powerful warlock Eames the law was eventually dissolved which leaded Piper to tell Leo she was pregnant 4 months later. During Piper’s pregnancy she gained the power of Premonition by tapping into her unborn baby’s powers, she also gained the ability to Orb.
Piper went into Labour on the 2nd of August at 11:00pm unable to get to the hospital in time Piper had to give birth in the manor, she was in labour for 4 hours during the pain Piper kept blowing stuff up and orbs started to appear above her stomach. After the intense pain Piper finally gave birth to Corey, when Piper let Phoebe hold him the both had a Premonition of Corey, Jonah and Maiya standing over the Book of Shadows revealing the future Power of Three.
During Corey’s life as a teenager he developed complete control over his Warren Power being able to call on Premonitions’ just by focusing on the item he was holding; he would still get surprise Premonition every now and then. During his senior year of High School Corey wasn’t very popular since most of his weekends consisted of demon hunting, he did have a few girlfriends but none of them lasted. At the age of 18 Piper was struck down and killed by the Triad devastating the entire family but it affected Corey the most, he spent a whole week casting spells or brewing potions trying to find a way to bring back his mother. At Piper’s funeral her will was read out after most of the belonging that Piper owned it finally came to her restaurant Halliwell’s which she left to Corey, this brought a flicker of happiness to Corey as he would be able to be connected to his mother through the way they both loved best cooking.
