Yes, here's four of them!
In the order of their creation?

CloakMan, ChairMan, KeyWoman, and WaterMan.

CloakMan's all the way from... 1998! That was the year RockMan and Forte came out... and playing it on an emulator was a bitch, so I actually imported it! That was the 1st thing I ever imported, and I still have it in <eBay terms> Like New </eBay terms> condition! Other rare MegaMan things I have collected: Playstation 1 MegaMan X3 and MegaMan Battle and Chase in English (European versions), and the weirdest thing of all, the MegaMan 3 Tiger Handheld game.

Okay, I'm rambling. But anyhoo, here's a little contest for you!
I named the weapons of each robot master in their pages:
C. Chair, M. Key, Cloak D., and Water M.

If you can identify what those abbreviated letters are, you'll win a prize!
Probably a little drawing or something... who knows.

Have fun!
