Ryuenjin

"Up + S.M. button on the ground. A powerful attack that burns enemies with flames. Some objects may be burned with this technique."

- In-game text

Ryuenjin, or Ryūenjin (龍炎刃), also known as "Dragon Flame Blade", is the special technique that Zero learns after defeating Magma Dragoon in Mega Man X4. By pressing the S.M. Button and UP on the D-pad while Zero is on the ground, he will jump up diagonally with a fiery Z-Sabre blade. This technique is quite powerful and is capable of striking multiple hits on a target, with the possibility of destroying them. Because of its nature, Ryuenjin can be used to burn the wooden pieces in Web Spider's stage.

Ryuenjin causes a weakness reaction against Cyber Peacock, Frost Walrus and Reaper Sigma's first form. It is also the technique which causes the most damage to Iris and Sigma's cannon form.

 * Minibosses such as Tentoroid and DG-42L and some bosses do not have an invincibility period when struck, so Ryuenjin can deal a tremendous amount of damage as it can inflict multiple hits. Damages listed on this chart is damage dealt per hit, not the total amount of damage done.
