Rekkyoudan (烈鏡断 Rekkyoudan? lit. "Violent Mirror Severing") is the technique Zero and Layer obtain after defeating Earthrock Trilobyte in Mega Man X8. This technique changes the color of Zero's Z-Saber to orange, allowing him to deflect energy projectiles with it. Unlike Tenkuuha in Megaman X4, which is applied to other special techniques as well, Rekkyoudan's ability is only applied to Zero's normal attacks. Once learned, the Z-Saber permanently becomes orange with Rekkyoudan activated for the rest of the game and there is no way to deactivate this feature.
