Derek Silberman (HERI)

Family
Derek does a terrible job at picking women. Shortly after he ends his relationship with Danielle Josephs, the mother of his two younger children, he tells Seth that he had a better relationship with Seth's manticore mother then he did with Danielle. He adores his children, but places a great deal of responcibility on Seth to help him raise first Peter and then Abby.

Powers
Although he had some abilities when he turned himself into a beast to get back his infant son, he lost those abilities when he was almost died and was returned to normal. This did imply some ability with potions, though.
