Soul Body

"Accumulates energy and generates an illusion. Enemies will sustain damage if struck by the soul energy. Requires high energy expenditures however and will dissipate in time or if it sustains heavy damage."

- In-game text

Soul Body (ソウルボディ) is the weapon that X obtains from Split Mushroom in Mega Man X4. When X equips this weapon, it creates a silhouette-like hologram of himself in front of him. In its normal state, the hologram does nothing more than mimic X's actions and will disappear after a short period of time, or after taking enough damage. When fully charged, it creates a solid, un-armored hologram of X that is restricted to the area of the current screen. Controls are passed to the clone - it can fire, but it cannot charge up like X can. Both X and the clone are immune during the duration. The clone hologram will disappear after a short period of time or if it falls into a bottomless pit. This weapon will severely distort Cyber Peacock and is the weakness of Sigma's gun form in the final battle against him.

In Mega Man X5, X will occasionally use this weapon against Zero (if the player chooses Zero). Unlike in X4, X can send many holograms at the player and is used as the final blow on the player.
