Invader Kim is an Irken Invader. He is the first Irken seen in The Nightmare Begins (albeit partially; all but his face was obstructed from view). In the same episode, he can also be seen in the line to get a SIR Unit. His antennae stick straight up and curl forward, contrary to the usual backward kink seen in most male Irkens' antennae. He is one of two Invaders to have a human-like name, one of the few without any spots on their PAK, and one of the many without stripes on their uniform. He resembles Zim in some ways, including his facial structure and the phonetic sound of his name.
