Gemini Man

Gemini Man (ジェミニマン) is a Robot Master that was created by Dr. Light and Dr. Wily. He is capable of doubling himself, and uses that power to his advantage. He is a narcissist, and likes to admire himself in a mirror or one double. He doesn't like snakes, because his weakness is the Search Snake.

Trivia

 * Gemini Man has a cameo appearance in Mega Man 10 as data of the Weapons Archive.
 * Gemini Man was the first Mega Man boss to be named after something astrological, in this case a constellation. He also has this name because he can create a "twin."
 * Of all original bosses, Gemini Man has had the most spinoffs, some examples being Axle the Red, Gemini Spark, Split Mushroom, and Gemini.
 * Ophidiophobia, or fear of snakes, may be a reason for Gemini Man's weakness. His MegaMan & Bass CD data backs this up.
