Harold Wilson is a recurring character in The Amazing World of Gumball. He is the father of Tobias and Rachel and the husband of Jackie. He appears to work as a psychologist.
Why He Sucks
He is incredibly egotistical, immature, and selfish.
He endlessly torments and humiliates Richard in “The Cycle” since high school and doesn’t give him a break.
He is willing to leave his wife Jackie for a younger woman in “The Cycle”.
He is a bad influence for his son Tobias
In “The Silence” he scammed Gumball and Darwin into paying him for his own personal pool house instead of giving him therapeutic help and gets no comeuppance.
In “The Castle” he pokes random people for fun and he starts a wild party in the Watterson’s home and refuses to leave and gets them kicked out.
In “The Shell” he cowardly abandons his wife in a car to save himself
In “The Cycle” when he thinks he’s rich from a fake blank check he finds on the street he mistreats everyone around him.
In “The Choices” where Nicole hallucinates a different life where she’s with him instead of Richard, and he manipulates Nicole to go out with him, makes their wedding all about him instead of her, and mistreats her. Although none of this happens, it shows how he would’ve acted.
He does get his comeuppance in “The Castle” where Nicole scares him into cleaning up their house that made a mess in, and in “The Cycle” where Richard tricks him into blowing himself and his house up with dynamite off-screen thinking he’s rich enough to buy a new one.
