Dad

Dad is a character in Homestuck. He is John Egbert's father, so he could be called Mr. Egbert. Dad is distinctly seen as having no facial features, a pipe where his mouth should be, and he wears a hat that looks vaguely familiar. He appears to be quite a giving man, leaving presents and encouragement for John all throughout the house on his birthday.

It could be speculated that Mr. Egbert is the Chosen Arbitor himself, as the notes and other clues point in the direction that Dad has been through a great deal of tribulation himself.

Dad unknowingly causes Strife to John, and uses his CoddleTech and Auto-Pastry abilities perfectly.
