If there's one thing I know gets a Mega Man fan excited, it's seeing Robot Masters. Over on the Rockman Online blog, the crew is showing the current setup for Rockman Online at the G-Star event in Seoul. From these images we can see Pharaoh Man, Cut Man and even the Mega Man Killers! An additional image also shows off Proto Man in a different armor style. As much as we've learned about Rockman Online, I still don't think there's any info on what all the classic characters are doing around. Hopefully that answer will be solved soon! Check out all the setup photos right here.
UPDATE: Some additional assets have been released via other Korean gaming sites. Hit the break at the bottom for more environmental scenes, better Mega Man Killer pics and a shot of Axl.
