Oooh, megaman thread!
First, I must defend my stance that Megaman is a white faced silent assasin. I had the European version of Megaman 1. I did play the second one as well, but I never owned it. Megaman had a light yellow skintone with white eyes in the early games (maybe just the first). The later games used a darker pink skin tone, and gave him more character development graphics. In the first game we're told very little about Megaman, there's hardly any art of him, the ingame sprite aside. Rockman (JP) has a chubby Megaman all over the main screen, but the EU version only has the logo. I'm sure people who played the later games have a different impression of the character.
I really disliked how they changed the gfx for the dropped stuff in MM2, but they made up for it with the cute little mini frogs and mini birds.
Here's my most recent take on
MegaGirl, but it needs to be iterated more. It's a bit similar to Atna's thing on page 2. I was never a fan of cone feet chubbyman.
I think MM9 should have been to MM what Dwarf Fortress is to RLs... 2D, but with massive feature creep. I don't mind breaking limitations. Hardware restrictions are useful to force a more consistent, unified, readable look. Sometimes artist can go a bit bonkers with pointless muddy gradients if they're given too many colors. I tend to think that the NES palette was a bit too restricted though. Another bitplane would've been nice, and a better global (64 color) palette.
I like Moleman. I think the 'body merged with head into a tube' shape has potential.
Hydralic man. Does he really need to use a black BG? Elaboration:

MtŪ's snow woman... I think I would skip the lips. in anime, lips are rarely pronounced on girls.
huZba, Tobe, delicious.
