The bosses detailed in the latest media update include Concrete Man, whose Concrete Shot weapon can create temporary footholds when it hits a solid surface. Tornado Man's Tornado Blow sweeps small enemies off the screen while damaging larger foes, and Magma Man's chargable Magma Bazooka shoots spreading fireballs.
As per the customs and traditions of previous Mega Man titles, the bosses forfeit their special weapons when defeated. Capcom further noted that more media detailing the remaining five robot masters will be unveiled in the near future.
While a North American release date for Mega Man 9 has yet to be announced, Capcom recently told Shacknews that it is aiming for a near-simultaneous release on the Wii, PlayStation 3, and Xbox 360's respective downloadable gaming services.
