Nermal is Garfield' nephew. He is a cute gray kitten. He flaunts his cuteness ("The cutest kitten in the world!", he says), which annoys Garfield immensely. He also has a very sarcastic attitude, which usually results in Garfield trying to ship Nermal to Abu Dhabi.
Garfield - Garfield hates Nermal, and killed him at the first chance he got. Before Garfield mutated, Nermal would annoy him and say he was cuter and better. Nermal needs to get a blood sample from Garfield for government purposes. When Nermal was in the attic, Garfield kills him in his snake form.
