Steel Devil

You can't do anything to stop this! - Dr. Wily activating the Steel Devil

The Steel Devil is the fan name for the unidentified giant robot that Dr. Wily uses in the climax of the Dreamwave Comics series, due to the high degree of resemblance it has to the Devil series of robots.

The exact size is a bit uncertain, but comparison between it and the tiny Mega Man and Proto Man at its feet suggests that it may be bigger than Gamma by a fair amount.

The Steel Devil is highly destructive as its initial activation was enough to obliterate the entire amusement park that Dr. Wily had been using as a hideout. Only the combined efforts of Mega Man and Proto Man were able to rescue Dr. Light from within and defeat the behemoth.
