Haha, I was going back through this thread looking for something and just realized I totally ended up making this
So... I've seen some alternate Bass skins around, but there was one in particular that wasn't made and that should be a nice add to the collection: Bass, as seen in Rock Man 7 FC. I think it looks nice.
Heh, I originally used these sprites for a Bass over Mega Man skin. There's some sprites you could probably use, I'll post them later.
To add to that, it's quite wonky (aligned incorrectly) and some sprites have the ring sliced a bit, and the portrait has a few pixels on the template lines. And those weapons. Why doesn't ring man even use his rings? They are a fitting substitute for either the buster shots or the metal blades.
The ring doesn't fit the Bass's buster shot as he attempted to do. If the Metal Blade can be programmed to the buster instead then it could work by changing it to the ring since Bass uses the Screw Attack in its place anyway.
You could at least have Beat perched on the ground. Keep in mind that the Toads and princess are static images.
