MM1 =
IceMan
Makes me feel like an Eskimo killer. He's far too "cutesy" for a stage so TORTUROUS.
MM2 =
FlashMan
This time, just going with the "Weakest Link." His level kicks ass, though.
MM3 =
SparkMan
Ditto, here. I love MM3 far too much.
MM4 =
DrillMan
Okay, maybe it's not his fault; but I expected his weapon to be much more useful or powerful than it actually was, and his stage was pretty atrocious. He coulda been so much more!
MM5 =
CrystalMan
His attack pattern is more annoying than challenging, and though his weapon design is wicked-cool, it's totally unutilized. I mean, imagine what an
uneven ceiling would've done for this fight! (There's really nowhere in other stages where it's helpful, either.)
MM6 =
BlizzardMan
Anybody wearing skis should move MUCH more than this snowman does. Seriously, he should just be "SnowMan," for all the fast-action he's known for. I associate both skiing -and- blizzards with fast motion, maybe it's just me, though. (Now, associate him with
FrostMan's level, and we're talking.)
MM7 =
JunkMan
JunkMan? Are you serious?! In a lineup with FreezeMan and CloudMan, ShadeMan and SlashMan comes this? At least his stage makes it work, though. Ironically, *this* fight is what I expected from DustMan.
MM8 =
AquaMan
Okay, his mid-stage boss is fun, I'll give you that. His stage makes good use of a few weapons, too. (I love the "Astro Crush the weak chamber" part, and how it plays on Super Metroid!) But the boss battle itself? Seriously, how did this guy get to the second four masters, where Frost and Grenade are in the first batch? Really.
MM9 =
HornetMan
Sorry. Mister Horny just doesn't do it for me. Level's a bit of a sting, too.
MMV =
Neptune
BOH-ring. Weapon is way too slow/valueless, too. It's like "CrystalMan" done WRONG.
MM&B = You know what? I'm torn here. They're all badass. But if I have to go with one...
[spoiler]
AstroMan
His stage was ABSURDLY annoying. His "miniboss" rooms were so basic, they make MM1 look smart. And MM8 had more bosses they could've revived besides this. GrenadeMan would make a -perfect- logical answer to DynamoMan, for instance. SwordMan would've been cool to see, too. Or even the Saturn remake of WoodMan! (In MM8, at least he had a fun stage to justify his presence in.)[/spoiler]
