Uh, from the games I\'ve played:
Gutsman: His weapon... drives me nuts.... and in Power Battles, his strategy is so predictable.
BubbleMan: I liked the design in itself, but... face it, he\'s the annoying underwater guy in every game. Plus,

Uh... can\'t think of one off the bat from 3. ^^;
Or 4.
WaveMan: Come on. What does anybody really remember this guy for? He\'s the filler water robot... with bubble jumping puzzles.
PlantMan: He\'s Woodman... with an even dumber strategy. And... they could have done without adding that creepy grin he makes after launching off those petals. And his power really doesn\'t seem to help a lot in this game. I like his music though.
Haven\'t gotten around to MM7 and 8 much yet, but TurboMan\'s fire puzzle was kinda annoying.

I agree with you, GutsMan gets those stupid cameos!

RingMan is a retard! Thats why I hate RingMan, he\'s reatarded.....

ToadMan. Is the kid who made him is stupid? Yes. Frogs JUMP, toads WALK!

RingMan is made by a reatarded girl. Whats her name?

I really hate the robot masters without hands. Just because they dont have hands, doesnt mean they still cant kick your ass. Ex: Crashman, Sparkman, and Drillman, the only three I really hate besides the ones with shields.

The one I hate the most is Iceman.

The other ones I really hate are:

megaman clones, crash, wood, spark, gemini, drill, wave, star, blizzard, flame, gyro man\'s, and the ever famous, Doc Robots.
But other than that, all are good.
