|Original Japanese Name||ビザック・S|
|Appearances||Zone of the Enders: The Fist of Mars|
Bizac S is piloted by Bolozof. It is stronger than Bizac, but Bizac is described as having a 'reinforced thruster unit'. Despite that, Bizac S appears to move at the same speed as Bizac.
Testament was intended to be Bolozof's next frame, but Bolozof never receives it. If the player takes the 24-story path, Bolozof instead receives Ifrit, an updated, mass-produced version of Testament.
