Dad (Wayne Forester, Horrid Henry) TTS Computer AI Voice

Dad (real name Simon, nicknamed Silly Simon as a child) is the father of Horrid Henry and Perfect Peter, Mum's husband and Fussy Uncle Francis' older brother. He doesn't seem to trust Henry in terms of behaviour at all. Almost every single day, he yells: 'Go to your room now, Henry!', as well as punishing him.

Dad works as an office manager at Tingly Toothbrushes. His work boss is Big Bob, and he's very strict. Dad doesn't seem to like Bob as a friend, but he does take him seriously when it comes to working. In terms of the way he gets treated by Bob and Henry, Dad prefers Henry's treatment than Bob as he is very strict and stresses him out.

It's been implied in many episodes, most notably "Horrid Henry and the Silly Siblings", that Dad was a lot like Henry as a kid.

Wayne Forester voices him.
