[MLDKF]

MM1: Bomb, Guts, Cut, Elec, Ice, Fire (I do Bomb Man first because I like Super Arm crushing Cut Man)
MM2: Metal, Flash Quick, Bubble. Heat, Wood, Air, Crash (I do Quick Man 3rd because I hate him and I want to get him out of the way.
MM3: Top, Shadow, Spark, Magnet, Hard, Snake, Gemini, Needle, Needle Again, Gemini Again, Shadow Again, Spark Again (I go with the Needle Man redo first because I want it done as fast as possible)
MM4: Toad, Bright, Pharaoh, Ring, Dust, Skull, Dive, Drill (Toad Man goes first for obvious reasons. Plus, the Rain Flush is somewhat useful.)
MM5: Gravity, Gyro, Crystal, Napalm, Stone, Charge, Wave, Star (I usually go after either Gravity, Stone, or Charge Man, but because of how useful Gravity Hold is and how much Power Stone and Charge Kick suck, I go with Gravity Man first most of the time.)
MM6: Flame, Blizzard, Plant, Tomahawk, Yamato, Knight, Centaur, Wind )Although Plant Man is the easiest, I go with Flame Man first so that I get the Jet adaptor, pick up the Power adaptor, and then I can get all the Beat Parts.)
MM7: Burst, Cloud, Junk, Freeze, Spring, Shade, Turbo, Slash (Although, you can pull off a funny glitch if you use Noise Crush right before you enter either Spring Man or Turbo Man's rooms.)
Rockman 7 FC: Spring, Shade, Turbo, Burst, Cloud, Junk, Freeze, Slash (Spring Man's the easiest)
MM8: Tengu, Clown, Grenade, Frost, Astro, Aqua, Sword, Search (I go after Tengu Man for the first half because the Tornado Hold is very useful. I also go after Astro Man for the second half because Astro Crush can absolutely destroy Aqua Man)
Rockman 8 FC: I never got around to actually beating it.
MM9: Splash, Concrete, Galaxy, Jewel, Plug, Tornado, Magma, Hornet (As much as I like Splash Woman, she's the easiest robot master in MM9, so I have to go after her first. Besides, the Laser Trident is a very useful weapon)
MM10: Sheep, Pump, Solar, Chill, Nitro, Commando, Blade, Strike (Sheep Man is the easiest robot master in MM10, plus, his Thunder Wool, while practically useless, can get me the Water Shield easily. Which is good, since it's probably the second best weapon in the game.)
MMX: Chill Penguin, Storm Eagle, Flame Mammoth, Spark Mandrill, Armored Armadillo, Launch Octopus, Boomer(ang) Kuwanger, Sting Chameleon (this one is complecated. Even though Shotgun Ice isn't Storm Eagle's weakness, it is Flame Mammoth's weakness. Plus, by defeating Storm Eagle, that makes traveling through Spark Mandrill's stage easier. Same thing with defeating Chill Penguin to make Flame Mammoth's easier and defeating Launch Octopus to make Sting Chameleon's easier.

[Korby]

[Alucard]

[Ivory]

I couldn't give an order. I don't even follow weakness orders. I just close my eye, hit the control pad randomly and select a random robot master!

Repeat for every robot master in every game.

[MLDKF]

mm8:
Clown, grenade (didnt know I could bounce bombs back)

[KillerChair]

Megaman 7: Spring Man or Cloud Man

Regular mm7 spring man first?... I doubt that  

[Ivory]

There's a code for mm7 that unlocks all the robot masters right from the start.
I wouldn't call it completely legit, but it is there.

[KillerChair]

I call cheating on that  

[Mr. Sean Nelson]

I don't know how much of a cheat it could be.
It doesn't exactly seem advantageous.
