Louie Watterson

Louie is very patient and calm, as shown in "The Man," where he endures Richard shouting at him for dating Jojo. Later on, he tries to resolve the argument with Richard "by sitting down, and having a calm, reasonable conversation." He displays extreme self-control despite Richard's provocation. He has a very kind demeanor with his new grandkids and he hopes to be a welcome member of the Watterson family, even gifting them fifty dollars and expressing a desire to spend time with them in "The Check."

In "The Signature" and "The Catfish," it is shown that Louie does have his limits. He decides to beat Richard at his own game when Richard tries to stop him from marrying Jojo, and he reprimands Gumball and Darwin when their trickery caused a fight between him and Jojo. Louie can be very talkative—he chats for hours over the phone with "Muriel" about his life story—and he is shown to be a romantic, waxing flowery terms about his relationship with Jojo. However, while he loves his wife dearly, he disapproves of her demanding and impatient behavior, as she prevents him from looking at other women and scarcely lets him see his old friends. Gay, secretly likes being a bottom, thick ass that hard to keep covered with bunny suit, slow flirting type, short, randomly gives hugs or cuddles when sitting with someone

Appearance: Louie is a black mouse with white paws, large round ears, and a big, dark gray nose that moves whenever he talks. He has several wrinkles around his eyes, indicating his old age. His ears also have a vague chalkboard-esque texture.

In "The Man," his nose becomes black, he becomes bigger, his mouth disappears, his outlines and limbs become thinner, his head attaches to his body, the white marks on his ears vanish, his wrinkles become more rounded, his ears become smaller, and his feet straighten. He was likely redesigned to make him easier to animate, as he would become a recurring character thereafter.
