Custom Mega Man Boss

[Thanatos-Zero]

It's still unnoticeable. He could get rid of the annoying extra layer.

Annoying extra layer? They aren't annoying at all.

Colourful bosses of the Rockman series use two layers.
There are only three bosses from the normal stage bosses (Namely Cutman, Bubbleman and Magnetman) on the NES which use one layer. However theses bosses have all in common that they always use white for the eyes.
The rest also use white on the sclerae.

Fortress Stage Bosses are a exception of the white sclerae rule, like the Darkman series of Megaman 5.
