Mega Man 4

Mega Man IV is the first Mega Man game to have someone other than Dr. Wily as the final boss!

Oh wait, no, never mind.

Pharaoh Man


A Sphinx miniboss was removed from Pharaoh Man's stage before release. While none of the background graphics for the Sphinx remain in the ROM, some of the object graphics do.



The Sphinx was definitely worked on after the above screenshot was taken: the snake is smaller and in a different pose, the boulder was also decreased in size (In the screenshot it's twice as wide as Mega Man, here it's as wide as him), and the Sphinx's chin is much shorter.



Presumably, this was the bullet that the little snake fired at you, which may or may not be the same one seen in the screenshot.

Dive Man


This seal robot was likely intended for Dive Man's stage, but it never shows up.



Some kind of...canister thing? It's stored with the sprites used in Dive Man's stage, right above the whale parts.

Miscellaneous Enemies


Some kind of telescoping thing that would stretch open vertically. Judging by the flashing light bulb weak point, it's probably an enemy.



A little gun on wheels that could raise up to shoot Mega Man in the face.

Miscellaneous Sprites


Dr. Wily and Dr. Cossack have unused pointing sprites intended for dialogue usage. No idea if they were supposed to be pointing at each other or not.

Miscellaneous Objects


Assorted background tiles that are never loaded. They seem to be labeled "B1".

Unused Function
A "darkness" function is used as part of enemy coding in Bright Man's stage. If used with Effect Enemy EX, its hex value is.
