—Gray Voice

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.

In the end, Gray Voice turned against Mother Brain and the Pirates, staging an attack on her while equipped with Chozo battle armor, although he acknowledged that the Space Pirates might retain control of Zebes regardless. Gray Voice later fought Ridley and was killed in the ensuing battle when Ridley used his tail to impale Gray Voice and then finished him off using his plasma breath.

It was Gray Voice who had donated his Chozo DNA to Samus, acting as a surrogate father, a fact she never knew until after the last time she had seen him, when she thought he had betrayed the Chozo.

He has only been named in the Metroid manga, though he seems to have originated as an unnamed Chozo in the Super Metroid comic. He may have also made an appearance in the Japanese endings for Metroid Fusion. He may have been the second Chozo depicted in the drawing that Samus was shown to have made in Metroid: Zero Mission. (The other possibly being Old Bird.)


Gray Voice's last words to Samus.

  • Gray Voice is one of two characters in the Metroid series that have acted as a surrogate father to Samus, the other being in a way Commander Adam Malkovich.
  • The manner in which Gray Voice was killed by Ridley was given a brief reference in Super Smash Bros. Ultimate via Ridley's Down Special Skewer, as well as in the trailer A Piercing Screech where Ridley killed Mega Man by impaling him in the chest with his tail.
    • On a similar note, the manner in which Ridley finished him off resembled the Plasma Scream Final Smash.
