The Mecha Dragon is a giant robotic dragon and the first boss of Dr. Wily's fortress in Mega Man 2. When it appears, it will chase Mega Man to the far right and destroy any platforms in the way. After reaching the end of the boss chamber where only a few platforms remain, the dragon will start launching fireballs from its mouth. Mega Man must avoid the fireballs and counter-attack, making sure not to fall into the pit below.
