Take out the Light Beam and use two Charged Shots on each knee when they are flashing. Do not bother about the feet. For the second stage, destroy the central antenna with a Super Missile or two. Note: You can only see the antennas with the Echo Visor. When you destroy the main body antenna, use a Charged Light Beam shot and two regular shots on each antenna. On the third stage, use a fully charged Light Beam to stun the head, then spider on the destroyed main body's legs. Boost onto the head when it comes by. Do this once more to defeat Quadraxis.
