GSU is a pale male android with silver hair and cyan eyes. He wears a white, sleeveless tight-suit and long black gloves with dull, white spikes on the knuckles. He also wears black thigh-high boots with white and cyan accents and silver soles. GSU tends to adorn a rather emotionless or uninterested expression on his face, which is reflected by his attitude. He acts emotionless but he really isn't. He refuses to share anything explicit about space due to "classified information".
