Invader Nen is an Irken invader who was assigned to an unknown enemy planet. He is short with a fairly large head, and two small, circular eyes. There are no stripes on his uniform, or spots on his PAK. His most notable features are his crooked antennae, which seem to be a trait unique to him. He also wears pink tights instead of the normal black ones, and boots that are a bit large for his feet.
