Shadow Devil

Shadow Devil (シャドーデビル) is another Devil type robot that appeared in Mega Man X5. He attacks similar to the original Yellow Devil, and his weakness (the eye) can appear on different parts of his body that can throw the player off-guard. After he loses a lot of energy, he will turn into Dr. Wily's Wily Machine from Mega Man 6 and will attack the enemy faster, making it harder to dodge his attacks. During the short duration of this form, the eye will periodically appear at the dome of the skull. His background music is a remix of the classic final stages, and a warped W appears in the background.

Strategy against Shadow Devil

 * Try using Tri-Thunder against Shadow Devil at his eye when he exposes it. That may do heavy damage.
 * If you are unable, try avoiding the blobs that try to hit X and Zero. And if the eye shows up, try to use a fully charged shot at the devil's eye.

Trivia

 * The Shadow Devil is considered to be the toughest Devil robot, as well as one of the toughest bosses in Mega Man history. This may also lead to an instant death for X and Zero if they are unprepared.
