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 give the player two different opportunities to counter them and obtain Full Synchro status.
