Dr. Psyche

"Perfect! You'll make a good specimen!"

Dr. Psyche is the "Computational Humanoid Reploid" from Mega Man X: Command Mission. His final form is the Mad Nautilus.

Dr. Psyche is a member of the Rebellion Forces and is very interested in the evolutionary capabilities of Reploids. He was an old research partner of Professor Gaudile and urged him to join the Rebellion Forces as well. Dr. Psyche eventually hunted down his old colleague to wrest the Force Metal Generator device he had created and was confronted by Mega Man X's command team in doing so. Dr. Psyche is crazed and power hungry as well as very likely insane. He makes long, almost ridiculous movements with almost every sentence he speaks, making him a fairly comical character, likely a byproduct of the later-revealed Supra-force Metal.

Upon his defeat at X's hands, Dr. Psyche separates his head from his dead body and attaches it to a larger, seashell-like body with tentacles dubbed Mad Nautilus. (Interestingly, this is the part of the battle where the traditional "WARNING!" light shows up.) Despite his protective shield, Mad Nautilus was eventually defeated by X.

In battle, Dr. Psyche always beings by summoning Needles to aid him and will summon more when they are destroyed. When he has Needles, he attacks by throwing beakers, which can affect player stats. In his Mad Nautilus form, he has a powerful shield that automatically counters any attacks performed on it. Eventually, the shield will drop as he charges up for an attack, allowing for the Hunters to attack without retaliation for a bit.

Trivia

 * His appearance makes people think he looks somewhat like a crazy Numberman.
