The Children of the Charmed Ones are the nine children of the Halliwell sisters. Piper, with her husband Leo Wyatt, was the first Halliwell sister to have children, followed by her sisters Phoebe and Paige with their husbands; Coop Halliwell and Henry Mitchell, respectively. These children are meant to carry on the great fight once they reach maturity. Paige and Henry's son, Henry Jr, is the only one with no powers due to being adopted into the family.
Wyatt Matthew Halliwell—Piper and Leo's firstborn child and older son. Wyatt's name is derived from Leo's last name, in honor of his father; his middle name, Matthew, is derived from his Aunt Paige's adoptive last name; and his parents decided for him to keep the last name Halliwell, because "evil fears it and good magic respects it". Wyatt was once destined to be one of the most powerful witches ever to walk the Earth as he was the Twice-Blessed Child. As a result of the prophecy that foretold his birth, Wyatt possessed numerous powers that are strong to an almost invincible degree: Projection, Shielding, Telekinetic Orbing, the ability to wield Excalibur, and many others. Unlike most witches, he had never appeared to have needed to "adjust" to his powers, and seemed to have full control over them from birth. However, the Twice-Blessed prophecy was later absolved, leaving Wyatt as a normal Whitelighter-Witch, though he still retained his multitude of enhanced powers.
Melinda Halliwell—Piper and Leo's third, youngest child and only daughter. She was named after her ancestor, Melinda Warren, and conceived after the Charmed Ones' last destined battle. She is the third-oldest of the nine children of the Charmed Ones. It was revealed that Melinda was a Whitelighter-Witch hybrid just like her brothers, due to some Whitelighter DNA still remaining in the then-mortal Leo, and the magic being brought out by the Elders due to their divine intervention. Due to this interference, Melinda developed the powers of Telekinetic Orbing and Hovering.
Parker Halliwell—Phoebe's second daughter, born approximately two years after her older sister. Cole Turner revealed that Phoebe was pregnant and she gave birth during the global magical switch caused by Rennek. Parker's powers are unknown.
Peyton Halliwell—The youngest of all nine children. After Coop Halliwell was judged in Court of Love, Phoebe realized she was pregnant with their third child. She was born 7 months after Prue died the second time. Peyton's powers are unknown.
Tamora Mitchell—The older of Paige's twin daughters. Tam has the active power of Molecular Acceleration, being able to basically use a lesser version of her Aunt Piper's molecular combustion power because she is still an infant. Unfortunately, after she accidentally set the house on fire, Henry and Paige made the decision to bind her powers until she grew old enough to control it.
Kat Mitchell—The younger of Paige's twin daughters. Kat came into her power of Molecular Deceleration shortly after her sister came into hers. She is said to have inherited this power from her Aunt Piper, as a lesser version of molecular immobilization, because Kat is still a baby, she only has enough power to slow things down and is yet to to freeze them. Paige didn't want to bind her power since it isn't as lethal or as dangerous as Tam's. However, it was later implied by Bailey that Kat's power was also bound.
Melinda Warren had a premonition of her family line continuing with many "beautiful daughters". However, Phoebe, the one she is touching, is the only Charmed One to have three daughters. Prue doesn't have children, Piper has two boys and one girl and Paige has two girls and an adopted son. (The Witch is Back)
The Triad worried that the Halliwell family will spread too wide in the future, by which they will be impossible to stop and therefore plotted multiple plans to destroy the Charmed Ones and prevent that from happening.
The Warren line of pure witches ended with Prue, Piper, and Phoebe, since Paige and the biological Charmed Children are either Whitelighter-Witch or Cupid-Witch.
In "The Charmed Offensive", the Angels of Destiny state that if any of the Charmed Ones' children inherit the Power of Three, it would be by natural means and not because external forces interceded. Obviously, Paige's children are out of the running to be Charmed as her last child is adopted. Some fans have theorized that the children would only become Charmed if evil got the upper hand again. Paul Ruditis stated in an interview that it would possibly be revealed whether or not the Charmed Ones have to die first before three of the children inherit the Power of Three.
In 2002, Phoebe was pregnant with a son with her former husband Cole Turner, who was possessed by the Source of All Evil. However, due to influence of the Seer, the child's demonic side was in control. After the Source essence possessed him, the child became pure evil. The Unborn Source died when the Seer stole the unborn child and could not handle its powers, vanquishing them both.
It has been speculated that because all of Piper's children have telekinetic powers and Paige's biological twins have split the molecular manipulation powers, that Phoebe's daughters will inherit her psychic powers.
Henry Jr temporarily possessed the power of Cryokinesis when mortals were given powers while magical beings lost theirs.
Parker and Peyton are the only ones who did not display individual powers.
Although purely mortal, Henry Jr briefly possessed the power of Cryokinesis when magic shifted from supernatural beings to mortals.
