Mega Man Xtreme was a game made for the Game Boy Color, and it's not unlike the regular Game Boy versions of the NES titles. With that said, this game borrows from the first two Mega Man X games heavily, using the same bosses and fortress structures. The bosses and regular characters used from those games won't be found here—only unique characters will be listed.

Middy

Middy was created by Dr. Cain to be a computer expert—more so than the other reploids. When some unknown foes hacked into a computer program of recorded data from X's past Maverick hunts, Middy helped X and Zero infiltrate the the software, uploading weapons, armor and other items to them. Middy was instrumental in helping to locate the hackers, but it came with a price.

Techno

Techno and his gang of Mavericks were responsible for hacking into the software containing X's past missions. His plan was to trap X within the computer world and use X's past foes, including Sigma, to destroy him there. When that failed, his allies left him behind as X blasted him away. Unbeknownst to X, Techno was Middy's brother, sharing the same power cell. So when Techno died, to X's dismay, Middy died also.

Zain

Zain was one of Techno's Maverick buddies. Because of his arrogance, he couldn't wait to be loaded into the system to face X. His attack pattern didn't include a whole lot of variety, but it was effective nonetheless. He'll start out by taking long jumps, swinging his huge blade each time; this takes up a lot of space, leaving little room to move. That's about it until you run into him again later. One thing changes at that time: After three or four jumps, he'll back into a corner and spin wildly with his sword. He'll then repeat this pattern.

Geemel

Geemel was another soldier in Techno's regime. When you do run into him, he'll begin the battle by transporting all over the place. He'll stay on the ground and begin blasting pellets, high and low, one after another, leaving little time to get your own shot in. After a while, he'll transport to the other side of the room. When you meet him again later, he'll fight the same way until his energy is depleted, wherein he'll begin riding a flying carpet, whipping from one side of the room to other. This is where he can damage X the most.
