Da is a very hard worker, wanting to harvest Amber Ogia quickly. In Bros in Space, Da didn't appreciate Rook becoming a Plumber, and didn't take kindly to Ben, especially since he destroyed a large amount of Amber Ogia during a fight.
For most of the episode While You Were Away, Da was brainwashed and had taken on the personality of Dr. Psychobos, alongside the rest of the planet. Once Ben and Rook destroyed the Mind Control Machine, Da and the other Revonnahganders regained their minds. Da then revealed that he is very proud of Rook and doesn't mind him being a Plumber anymore and also respects Ben.
In Rook Tales, Da gives his blessing to Rook Shar, who wants to became a Plumber. He says he is very proud of her. Just like any other Revonnahgander, he deeply respects the elders. He was willing to protect his daughter from Master Kundo, knowing that he would get hurt badly.
