I've selected the following 10 robot masters from the original 78 based on the series' debut title, Mega Man for the NES in 1987, all the way through to Mega Man 10, released as downloadable content on WiiWare, PSN and XBLA in 2010.
After weeding out the rest, I ranked those that remained according to a three-tier process, beginning with the ones that scored the lowest out of 10 for each category. First, I started with the overall visual design of the character, and then accounted for the complexity of their attack patterns.
Lastly, I throw a coolness factor into the mix based, for the most part, on my first impressions of each because let's face it: if you can't trust your gut, what can you trust?!
Here are the 10 best (and worst) Mega Man Robot Masters!
