White Axl

"White Axl", labeled as ??? in-game, is a special unnamed upgrade for Axl in Mega Man X8 that enhances his abilities. With the white armor, Axl can hover infinitely while firing, his ground dash is longer and faster, and he can remain transformed for an unlimited amount time. His firearm attack power will also be increased by 50% when this armor is used. His x-shaped scar that is present in Normal Axl will also disappear in this version.

Unlocking
This armor can be unlocked in one of two ways:
 * 1) Purchase all of Axl's personal Chip upgrades. Then you need to have Axl dealing the final blow on Lumine (Double Attack is not necessary in this case but Axl must be the one that defeats him) before saving into a New Game Plus. Once this is done, White Axl will be immediately available for selection.
 * 2) On PS2, input x3,  x3,  x3, and  at the title screen while "Press Start" is flashing. If inputted correctly, Axl's voice can be heard saying "I'll take care of it", confirming the code. You must then choose either Normal or Hard mode.

Ability
When using this form, Axl will infinitely suspend in midair as long as you hold the shoot button. Then you can also redirect your fire in all 8 directions. It is also very useful when you are trying to delay your fall or reaching far away walls, ledge, platforms and areas. Can also be used as a trick against grounded enemies

Trivia

 * Given Axl's look with the white armor and his ending in Mega Man X8, it is speculated that the shard of Lumine that was implanted into Axl's helmet through his broken crystal lens is the cause of this armor, which colors are similar to Lumine. However, this has not been confirmed, and the shard has not been expanded on, as it is not seen later during the events of Mega Man X: Command Mission; though this is probably because Mega Man X: Command Mission was released before Mega Man X8.
