Robin Knight is the father of Robin Mask and grandfather of Kevin Mask.

Robin Knight is the son of Robin Grande and the father of Robin Mask. He is shown to be a strict and rigid father, but one with a prejudice against humans, as he wishes for his son to retain his Choujin status and not marry a human. There is very little seen of him, outside of flashbacks, but - due to Robin having other trainers early in the series, as opposed to other choujin often being trained by family - it can be inferred they have a strained relationship.
