Kenneth is a minor villain in The Amazing World of Gumball. He is a monster made entirely out of disgusting things that was created by Gumball in "The Microwave".
Kenneth was created by mixing together various disgusting things (snotty tissues, bird feces, and regurgitated spoiled milk) in a jar, which was then put through the microwave. After this, the gross mixture somehow gained a life of its own. Kenneth is a greyish-brown vaguely humanoid monster. He seems to have a very loose body form, and he looks constantly runny. Kenneth has a large mouth filled with razor sharp teeth, and when he grows to a larger size, his eyes start to glow white.
Kenneth seems to be a malicious and dangerous beast. The only thing he seems to enjoy doing is eating people, and once he manages to eat someone, he grows a little bit bigger. He first attacks Gumball and Darwin, but they mistake it for simple hunger, so they feed it. Eventually, he then eats the mailman and Anais but does not want to eat Gumball and Darwin, which shows that when it was made he was a bit sympathetic towards them. However, when he ate Richard he seems to have lost his sympathy toward the duo who claimed to be his mother and father, roaring and growling at them.
- The list of characters that he ate in "The Microwave" (in chronological order):
- It is unknown what happened to Kenneth after "The Microwave", but it can be assumed that he was captured by the government or destroyed.
- Kenneth and his motives seem to be inspired by the monster from the classic movie The Blob.
- A photo showing him fighting Hector was seen on a storyboarder's website, meaning he will make an appearance in the upcoming episode "The Finale".
