Split Heavens

The Split Heavens, known as Tenretsujin (天裂刃) in Japan, is an EX Skill from Mega Man Zero 3. It is a rising slash, that causes Zero to leap upwards with Z-Saber extended to slice enemies above, and can only be used on the ground. It can be made fire elemental if used with the Flame Chip. It is obtained by defeating Hanumachine R with an A or an S rank. With the normal Head, Light Body and Quick Foot chips equipped, Zero will perform this technique after the third saber slash by pressing up at the end of the combo. Timing is crucial with this maneuver, since it is possible to trigger the rise slash (the one where Zero stays grounded and moves his saber upwards) instead if it is enabled.

This EX Skill also appeared in the Rockman Zero manga, where it was misnamed as Retsutenjin (裂天刃).
