Although Gumball can be intelligent at times, he is not very wise, often doing things in the most convoluted of manners and gearing his energy towards fruitless endeavors.Although Gumball can be cynical towards society and the people around him, he ultimately does believe that there is a supposed way out of such a lifestyle.
In both cases one has to be certain about the creator's intentions about who's sympathetic and who is right.
Please note that Tropes Are Not Bad, as this can sometimes appear to happen, but its actually done on purpose to add more shades of grey to a story, or to show that the heroes are not completely perfect.
They might even be sympathetic by virtue of their social position.
Any astute arguments and observations by this character are to be dismissed by the audience, because they are Evil.
Darwin Watterson is Gumball's foster fish brother and his best friend.
He was initially Gumball's pet fish, though he was promptly integrated into the family once he grew legs and lungs.
However, Anais suffers from a lack of social skills, struggling to make and maintain friends.
Nicole Watterson is a blue cat and is the loving mother of Gumball, Darwin, and Anais.
Naturally, this can boomerang back onto the protagonist: in-story, a Designated Hero is regarded as 'good' despite having no significant virtues.
Conversely, Protagonist-Centered Morality isn't a case of having weaksauce villains; it's a personification of being an ass for its own sake, and being lauded for it.
Anais's intelligence trumps that of both of her brothers and she attends a higher grade level then them.
