Gray Voice(グレイ ヴォイスGurei vu~oisu) (also translated as Grey Voice) is a Chozo from Zebes, and was one of the Chozo who found Samus on K-2L. Gray Voice objected to allowing Samus to stay on Zebes after she was orphaned on K-2L, but agreed that there was no alternative. He was close with Old Bird, but when Zebes was under attack he pretended to assist Mother Brain in allowing the Space Pirates to take control of their home planet, becoming a leader with her. The two of them offered Samus a leading position, though she refused.
