Derek

Derek was a mortal and mate to a female manticore. 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 in doing so, became a vicious beast known as "The Beast".

His search eventually led him to the Charmed Ones, but because Wyatt's forcefield 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 succeeded. He and Piper then have a parent-to-parent talk, and Piper finally decides to help him. Phoebe and Paige, wanting to save their sister, contacted the Manticore pack for help in attacking both Derek and his son. After the manticores took his son and left him fatally injured, he was turned back into a human.

After Piper, Phoebe and Paige were able to return the baby back to Derek, he left and restarted his life as a human.
