Love life
As a whitelighter he was assigned to the Charmed Ones and posing as a handyman, Leo met Piper. Although Phoebe was interested in Leo he made his interests clear. Through the years Piper and Leo’s love has been tested many times. They were unable to get married as it was against the rules for whitelighters and charges to fall in love, and were put on magical probation by the Elders. But after proving that their love was true the Elders had no choice but to allow it. Piper and Leo had biological problems conceiving a child managed to give birth to Wyatt Matthew Halliwell, their first son. They were both confused by his arrival as all children of the Warren line have been women and Piper and Leo had seen their daughter in thefuture. Later Chris was born but not at the manor like Wyatt.

Powers
Blessed with powers of all kinds Leo, like Paige, can orb from place to place, sense his charges (he cannot if they are in the underworld or dead), heal, levitate, change his appearance and can speak any language his charges are speaking. After the release of the Titans and the demise of lots of Elder’s, Leo became an Elder. However after the betrayal of Gideon, Leo was tricked by the Avatars into killing Elders. In order to provide the best life for his family, Leo became a Avatar and helped in the change of the world to a Utopia. The Elders were told about Leo's new found powers and was considered for recycling but was finally made mortal, which he continued to be. However, being mortal didn't stop him from becoming headmaster a magic school, after they reclaimed it from the demons. Leo continued to be headmaster until it was time for him to retire.
