Invader germ is a 14 year old (140 in human years) irken with a lot of energy, and no one to waste it on. She has green eyes, green skin, long messed up and bent antennas with curls on the end (since female irkens have that curl on the end) and a green invader uniform. She added two studded belts, and some striped arm warmers to the uniform. She wears big green and black boots, and is about 5'1. Her relationship with zim, a fellow irken invader is like that of a sibling, even if they aren't.
