"We're under attack! Hide like cowards, kids!"
-- Daddy while the house is under attack from the DNK
Being the opposite of Father, he is very kind and cares for his children very much, but is also cowardly and unwilling to get things done. Father is mostly brave while Daddy is cowardly. He is first seen hiding in a closet in the LTDFCD's trailer and comes out when they return home. He told positive Numbuh 1 and Lizzie about the DNK and when the DNK show up, he goes into the closet again just as the trailer is blown up.
- Although this episode predates Z.E.R.O., the character model had previously been used for "Mr. Wigglestein" in Operation: A.R.C.H.I.V.E., who later in the episode, was revealed to be Father.
- They also share the same voice actor (Jeff Bennett).
- His real name could be either "Tcidineb Nietselggiw" or "Tcideneb Onu", although neither has been confirmed.
