This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

Mega Man Zero 4 is the final game of the Zero subseries, and we finally get to see these "humans" that the X and Zero series have been talking about constantly. Oh, and Dr. Weil's back. He's still crazy.

Not as much collecting this time: there's only one Cyber-elf! However, there are a lot of head/body/leg chips to create, so get to enemy farming!

Unused Graphics

Untranslated Icons

Two unused buttons that were not translated for the American and European versions. They translate as "Back" and "Close".

Preliminary	Final

These buttons would have been used on the Elf Menu. They were likely removed because it was easier to just use B to navigate through the menu, and removing them gave room for two more lines of text. There was really no reason to keep them, so out they went.

Unused Weapon

Animation group 517 in the Collection contains an odd looking sword. It is next to weapons and projectiles used with the Z-Knuckle. Given that it does not fit the art style of the rest of the game, it may have been taken from another project and used as a placeholder.

Zero 3 Leftovers

Located in animation group 392 is the charged shot animation used by Omega Zero.

Regional Differences

Prologue and Credits

The Prologue and Credits music tracks lack vocals in the international versions. The Japanese ending theme is used in all versions of Mega Man Zero Collection & Zero/ZX Legacy Collection, even in English.

There is however an unused track for Zero 4 in Zero Collection that could be the international version of the ending theme, but the first part where the singing was originally edited to remove vocals is very unfinished (nearly no instruments).

Sprite Changes

Blood Spray

When most enemies are destroyed with a non-Buster weapon in the Japanese version, a viscous crimson goop flies out of them. Like the other games in the series, this was removed from the international versions.

Boss Icon

Japan	International

As Dr. Vile's name was changed to Dr. Weil outside of Japan, the icon was changed from a V to a W.

Title Screen

Japan	US	Europe

Yeah, Europe, you got screwed again. It looks even worse against that background art.
