Favorite/Least favorite weapons from each game

[Myroc]

Thunder Wool suffers similar problems that Hyper Bomb does in MM1. It has a ridiculous wind up time, which makes hitting anything mobile with it rather difficult. Anything that moves will most likely have gotten past the cloud you shot before the lightning bolt appears. On top of all this, it consumes so much ammo you won't ever be able to use it more than a few times.

[Max]

I use the Thunder Wool on bosses! Pump Man and Nitro Man are easily defeated by it due to their constant back and forth behaviour, bosses like the Block Devil can be hit multiple times and the Crab Puncher can be hit twice in one attack! It's bad on enemies but it's certainly not useless.

[Myroc]

I've seen Thunder Wool being used against Nitro Man but even then it's probably much more effective trying to buster him, since it is by no means a fast way to kill him, and you'd be required to pull off pretty neat jumps and have incredible dodging skills.

[BiscuitSlash]

Well, have you ever tried using it on sniper joes or shield attackers in an open room? Unless you screw up, they will be hopeless! Also, next time you get past the mid point in blade mans stage and you have thunder wool with you, use it immediately after landing and that spider thing gets killed instantly. Honestly, Capcom may release flawed weapons such as spark shock and power(?) stone but no weapon is actually USELESS.

[Myroc]

I'll agree that it's not completely useless. Hell, even Spark Shock has its uses from time to time. It's just that among all the 8 weapons you receive Thunder Wool is probably the least useful. Even chill spike can be used better. It might be useful in certain situations but such situations are few and far between.

[BiscuitSlash]

I'm surprised that I haven't seen much hate for spark shock. I mean, apart from some bosses being weak to it, the only enemies that I know it works well on are those armored big eyes. Most other things it is just so much more easier to just shoot and pass with the buster of a different weapon. At least thunder wool actually does something. (I find rebound striker harder to use than thunder wool actually)

[Nuy]

It might be useful in certain situations but such situations are few and far between.

Pepole say that about a lot of weapons but I've yet to see one of those instances. Yeah sure it hits Nitro Man alot, Chill Spike is easier to use AND does more damage. Despite almost every weapon in MM10 being awful, I have to say Thunder Wool is the worst in the series Dethroning the Sakugarne as the worst weapon in Mega Man. Top Spin kills thing, Thunder Wool doesn't. Even if you wait the 7 years it takes for the lightning to come out, it only does 5 damage which can't even kill MM10's big eye eqivelant in less than 2 hits. Even the boss thats weak to it can be killed faster with other weapons!

[BiscuitSlash]

I just leave you with this:

No weapon in the series is truly a terrible weapon. You've seen in this thread that different people have different favorites and most hated weapons. It all depends on how well the player know how and when to use the weapons. Yes there are flawed weapons such as spark shock and thunder wool, but even those have uses, more than just boss weaknesses. (But thunder wool is still better than spark shock)

MM1: Rolling Cutter. Sure, Fire Storm and Thunder Beam are more reliable, but there's just something lovable about the goold old scissors.
MM2: Quick Boomerang is fun to mess around with.
MM3: Hard Knuckle. ROCKET PAWNCH!
MM4: Drill Bomb. Really powerful, and makes a delightful kaboom sound.
MM5: The weapons here are a bit lacking, but I'll go with Star Crash. Comes in handy more often that most MM5 weapons, IIRC.
MM6: A lot of good stuff here, but I'll go with Flame Blast for the sheer power.
MM7: Noise Crush. Just gotta get the hang on sliding into it...
MM8: Water Balloon. Hey, you said FAVORITE weapon, not BEST... XD
MM&B: Wave Burner. Nothing like roasting the enemies with a flamethrower.
MM9: Black Hole Bomb. Eats everything for breakfast.
MM10: Wheel Cutter. WHEE SHORTCUTS!

MMI: Bubble Lead. Got a surprisingly big damage boost.
MMII: Sakugarne: Such an awesome concept, but...
MMIII: Gemini Laser. Another one that got buffed up in the move to monochrome.
MMIV: Beat. He counts, right? He's pretty darn strong in this one. Otherwise, Pharaoh Shot.
MMV: Break Dash and Electric Shock. All the fun of a better Charge Kick and pretending to be Emperor Palpatine.

Megamari(Yeah, yeah, I know): Psycho Missile and Rolling Slash. The former is like a hi-speed Flash BombHard Knuckle hybrid, the latter is Top Spin on drugs.

As for least favorites...

MM1: Hyper Bomb. Just too unwieldly and slow.
MM2: Atomic Fire. Not worth the charge time, annoying sound, and high ammo cost.
MM3: Spark Shot. It's only bad due to a few programming oversights, though. It was worth using in MMIII.
MM4: Dive Missile. The aiming is juuust a bit wonky.
MM5: While it's not really the worst MM5 weapon, I'll say Gravity Hold for being the weakest screen clearing weapon, hands down.
MM6: Wind Storm. Blowing enemies away is funny, but theh they don't drop powerups...
MM7: Scorch Wheel. I've just never found a decent use for this besides getting Beat. Heck, Freeze Cracker even does more damage to the RM's weak to Scorch Wheel!
MM8: Thunder Claw. Not that it's bad or anything, I'm just terrible at swinging with it. XD
MM&B: Spread Drill and Ice Wall. Spread Drill is pretty darn weak, actually, and I've always found Ice Wall to be annoyingly awkward.
MM9: Hornet Chaser. It's still useful for grabbing stuff, but it's the only weapon that doesn't curbstomp half the enemies.
MM10: Commando Bomb. I tend to move while shooting, and it really throws my aim off.

MMI: Time Stopper. Just not much use for it here.
MMII: Sakugarne. It's glitched me out of the final boss more times than I can count...
MMIII: Skull Barrier. Seems a bit less useful than it was in MM4.
MMIV: Power Stone. It did get a bit of a buff, but it's slooooooow.
MMV: Deep Digger. Even more situational than Super Arm.


Megamari: Ghost Cutter. Basically a crippled Slash Claw.

[CHAOS_FANTAZY]

I guess it's obligatory.

WINNER FOR MEGA MAN 1 IS...
FIRE STORM!
This all-around useful weapon has the ability to hit all around you (no pun intended) .  Like a prototype shield weapon, Fire Storm is good for picking off fodder.  It's projectile is wider than a Buster bullet, making it easier to aim.  Overall, I don't know how I would've survived Wily Stage 2 without it.
WINNER FOR MEGA MAN 2 IS...
METAL BLADE!
I said it.  
WINNER FOR MEGA MAN 3 IS...
SHADOW BLADE!
The lovechild of Rolling Cutter and Metal Blade, the Shadow Blade can be aimed in all 8 basic directions, but comes back in case it missed the first time.  While its low range is constricting in the open, it DESTROYS bosses that stand still...*Cough* Gamma! *Wheeze*
WINNER FOR MEGA MAN 4 IS...
RAIN FLUSH!
The most OP weapon of its day, Rain Flush kills all basic enemies.  Instantly.  Everywhere on screen.  Those motorbike things would have a whole lot more kills on me if it weren't for this poor guy's awesome weapon.
WINNER FOR MEGA MAN 9 IS...
HORNET CHASER!
While not very practical for fighting, Hornet Chaser is a useful weapon indeed.  Illustrated by hiding items inside walls, the Hornet Chaser's main use is grabbing items for you.  It coaxes Stone Head out of his hiding place (not too good at dodging them rocks) , and its accuracy is that of Dive Missile.
WINNER FOR MEGA MAN 10 IS...
BASS BUSTER CHILL SPIKE!
I always enjoyed freezing weapons.  Time Stopper nommed all your energy at once, though, and Flash Stopper was a bit un-precise.  Chill Spike, with the highest ammo count and ability to do damage, is a clear winner.  Its freeze time is more than respectable--plenty to launch your next attack on the field enemy.

Least favorite from each game:

MM1: Hyper Bomb
MM2: Bubble Lead

MM5: Gravity Hold
MM6: Again, I don't know. I never beat any RMs in 6.
MM7: Scorch Wheel
MM8: Water Balloon
MM&B: Ice Wall
MM9: Concrete Shot
MM10: Thunder Wool

Best of the Classic series: Rebound Striker (love having the Giant Bouncing Ball of Destruction in my arsenal)
Worst of the Classic Series: Thunder Wool (this weapon is so damn difficult to aim and I would rather that Capcom recycled Thunder Beam, Thunder Bolt or even Plug Ball rather than combining wool and electricity to give birth to the most useless weapon ever. At least it isn't the weakness of Wily Capsule 10.)
