- "Tenkuuha: Enhanced Z Saber! You can cut enemy energy shots with your saber."
- ―In-game text, Mega Man X4
Tenkuuha, or Tenkūha (天空覇 lit. "Aether Rule") is the special technique and Z-Saber upgrade that Zero learns after defeating Storm Owl in Mega Man X4. This technique is based off Storm Owl's ability to absorb damage from some types of energy attacks. This technique changes the color of Zero's saber to a violet color, allowing him to destroy energy projectiles with it. The Z-Saber does not become any stronger with Tenkuuha and there is no way to deactivate this feature, which is similar to the Kuuenzan's; once learned, the Z-Saber permanently becomes purple with Tenkuuha activated for the rest of the game.
The ability is reused as an upgrade for Zero's black armor (with some extra enhancements) in Mega Man X5, and as the Shot Eraser upgrade in Mega Man X5 and X6. It also appears as a skill in Project X Zone.
Counterpart to this Technique
- Being Double Cyclone's counterpart, this technique should be Magma Dragoon's weakness and stun him, but it doesn't. In fact, Magma Dragoon's weakness is Raijingeki and doesn't stun him either, only slows him down.
- When playing as unarmored X without special weapons equipped on the X Challenge mode from Mega Man X Legacy Collection 2, the Z-Saber will be purple instead of green for the fights against Vile MK-2 and High Max on Stage 3-3, and Gate and Dynamo on Stage 9-3 (both fights are in Volume 2 only). High Max can't be damaged without the use of special weapons, so the Z-Saber will count as one if special weapons weren't selected. Gate's orbs can be destroyed easily with special weapons, so using the Z-Saber will allow X to destroy them fast without having one.
- This saber although similar in coloring, is not exactly the same, as this one is slightly brighter.
- Although similar, this purple saber doesn't seem to have the shot eraser function.
