Middy

Middy (ミディ) is a character from Mega Man Xtreme.

He is a skilled programmer who manages the Mother Computer throughout the game.

Middy's twin brother, Techno, was manipulated by Sigma, and attempted to hack into the Mother Computer by uploading himself into the mainframe. Sadly, when X destroyed Techno's terminal to prevent Techno from hacking the Mother Computer, he also destroyed Techno's CPU, and because Techno's CPU was linked to Middy's, Middy too was killed.

Trivia
Despite having appeared in but one game, Middy and Techno have become popular amongst fans, likely for their cute looks and personalities.

His name is clearly a reference to MIDI audio format.
