Nicole Watterson

Nicole cares very deeply for her family, so much that she would do anything to express her love for them. She is also very protective of her family, as seen in "The Ape." Since she is the backbone of the family, Nicole does most of, if not all, the household chores, and in addition, she works long hours at the Rainbow Factory just to put food on the table. Often, when she competes against the rest of the family, it is "for" the family, such as when she wanted to watch Win or Don't Win to win a new microwave in "The Remote."

Unfortunately, Nicole also suffers from a tremendous amount of emotional stress because of her many duties. She is also quite strict and a demanding mother, and sometimes has extremely nasty temper issues when upset. In fact, on one occasion, Gumball decides it would be easier to face Tina than an angry Nicole. Despite all that, Nicole is still a good mother and person, very supportive, kindhearted, forgiving, has a softer side, and she still loves her family very much.

Nicole can be quite stern when provoked, and occasionally vindictive, as was shown in the episode "The Ape," after Miss Simian called her and her family "losers." On top of this, she has also proven to be very resourceful and inventive, a trait she most likely passed on to her daughter Anais, who has demonstrated similar talents — in this case, strategically setting a mine-like trap in a paintball arena/forest, merely using environmental supplies, and whatever she took with her. Winning seems to be a necessity for her at times, most likely due to her mother's ambition for her to succeed in her youth. Though, despite her somewhat ruthless faults, she can accept defeat, acknowledge her mistakes, and even find humor in them.

Thanks to her ever-increasing temper, Nicole manages to get things done much quicker than the other characters. She also does not like losing, as shown in "The Game," but still does not prefer to fight those who had a close relationship with her, such as Yuki, unless they threaten her family or her job. Doctor Nicole Watterson (née Senicourt) is one of the main characters of The Amazing World of Gumball.

Nicole is the mother of the Watterson family and is the backbone and only truly responsible member of the family.

She is very dedicated to her family and would do anything in her power to keep them comfortable and safe.
