|“||Cool! That means I can kill monsters and sing in the same time!||”|
— Mabel Watterson, when she became a monster killer
Mabel looks almost similar to Gumball, the exception is that she have brown hair and eyelashes.
She, like Aguilera, changes her clothes daily. Her Season 1 casual outfit are a dark coral band, a dark coral sweater with a shooting star, a purple skirt and white shoes with black sole.
But, in Season 2's first episode, just the shoes aren't change. She wears a turquoise band, a white sweater with a turquoise clover and a turquoise skirt.
In Season 2 onwards, she has blonde hair streaks with dark grey bangs and edges in a ponytail and wears a turquoise shirt with trail, blue 3/4 pants and orange sandals.
She wears blue eye contacts (it's not cataracts) due to blurry eyesight.
Mabel is a fun-loving, imaginative, rather optimistic,day-dreaming, and a very mischievous cat.When her mishaps get her into a mess, she usually attempts to fix things with somewhat dimwitted ideas, which usually get her into even more trouble than before. No matter how her schemes resolve themselves, Mabel's naivety stops her from causing troubles, even as almost a teenager. Mabel has a big ego and it is where she is most sensitive. Otherwise she is usually positive on all matters concerning her. Mabel is very smart, but that doesn't mean she's a smarty pants,like Catrin or Cobby. At times she acts not much stupid and goes to great illogical lengths to find something, but she has shown some degree of cleverness in other circumstances. She happens to have a superior vocabulary, using more mature words. Mabel has also displayed extents of observance and operational solutions to identify small things. Her antics have gotten her into dangerous and often life-threatening situations, usually saved by luck or someone more sensible at the time. She has shown skill in building, though Gumball failed stupid in the end.
She can also be very romantic at times and shows it to Cobby,her boyfriend,often landing in suggestive moments that almost sometimes ends up with another problem.
