Derek

Derek was a mate to a manticore demon. He managed to get away before she had the chance to kill him after they conceived a baby. Since then, he used all kinds of magical potions to experiment himself in hopes to become strong enough to take back his son, and so became a vicious beast, known as "The Beast".

His search eventually led him to the Charmed Ones, but because Wyatt's force field was protected against him, he kidnapped Piper in hopes to use her as leverage. When she refused, he went to take back his son again and succeeds. He and Piper then have a parent talk and Piper finally decides to help him. Phoebe and Paige wanted to save their sister, so they contacted the Manticore pack for aid, then go after Derek and his son together. After the manticores took his son and left him fatally injured, he was turned back into a human being.

After Piper, Phoebe and Paige returned the baby to Derek, he left and re-started his life as a human.
