00's Voice (ダブルオーの声, Daburuō no Koe) is the eleventh episode of the Second Season of Mobile Suit Gundam 00.

While Ian Vashti and his fellow Celestial Being mechanics prepare the O Raiser, a support machine for Setsuna's 00 Gundam, the A-LAWS deploy a devastating new weapon of their own. Tieria is outraged by the actions of Ribbons Almark and the A-LAWS, and he finally reveals the existence of the Innovators to the crew of the Ptolemaios 2.
