D-1000

D-1000 is the boss of the intro stage of Mega Man X6. It is comprised of a large, seemingly immobile Mechaniloid and a smaller robot that operates it from above.

Attacks and Strategy
It mainly attacks by charging into you, either from above (which can be avoided by ducking) or by adjusting to your altitude and charging from the left or the right (depending on where you are). When enough damage is dealt, it may also fire energy balls from its mouth that explode upwards when they reach the ground. The eye orb avoids you by teleporting from one side to another, but can also fire slow moving orange shots at you.

Striking the eye orb not only damages it more, but makes the big Mechaniloid crash into the ground and immobilizes it momentarily. The large body can also be hit, but it takes much less damage and does not become immobile.
