Jeremy

Jeremy is the father of Kaz, Katie, Kenny, Kevin, Kaylie, Kasey, Kyle, Karen, Kasy, K, and 1 unknown sibling. His last name is unknown because Kaz never reveals his last name. Coincidentally, like his son Kaz, he's a doctor (not a superhero doctor). He is half Irish half Spanish.

Relationships
Because he has 12 children, he gives his younger 6 undivided attention in hopes that they don't end up in jail like some of his eldest children, whom he doesn't pay much attention to. Kaz never mentions either of his parents' names in the 1st two seasons. Kaz asks for his help in Season 3 when Phillip suffers an unknown brain injury.
