Dark Mech

DarkMech, known as Assassin Mecha (アサシンメカ) in Japan, is a virus in the MegaMan Battle Network series that resemble a robot with sword hands. They only appear in Battle Network 6.

DarkMechs attack by shooting out a Thunder Ball (similar to the Billy viruses) that track MegaMan. If he is struck by the ball, the DarkMech will warp in front of MegaMan and slash him with a Wide Sword-style attack. Because DarkMechs have two attacks, they have two Full Synchro oppertunities.
