Marble Gardens boss from Sonic 3? I'm just grasping at straws here... <<
nopers.
The Panic Puppet boss in Sonic 3D Blast?
Nup.
ETA: Here's another clue.
9). You can stock up shortly before.
Metropolis zone boss?
1). Destroying it only makes it harder.
Destroying the parts that come out of it make it faster and iirc, launches more of the bubble things at once?
2). Two is better than one.
Two players vs the boss is better then one, ergo, two players playing as Tails and Sonic is better then just Sonic and A.I. Tails mental hilarity.
3). Don't stand still for long...
If you dont, youll get hit.
4). Quick, save me!
Not sure on this one, tbh.
5). In other circumstances, it can rise up and down.
The boss pattern of movement involves moving from left to right, rising up and down as it does.
6). You'll be here again
You fight a variant of it in Sky Sanctuary in S&K
7). Mega Drive
Its in Sonic 2.
. Stop - Hammer Sonic Time!
Dont know.
9). You can stock up shortly before.
Stock up on rings?
Nope!
10). Angel Island
I wanna say the Ice Cap boss.
1.) Destroying it only makes it harder.
If you destroy the platform, he just shoots even more freezy fog.
2.) Two is better than one.
Eggman's ship shoots 2 ice streams?
3.) Don't stand still for long...
Or you'll get frozen.
4.) Quick, save me!
If you are frozen, Tails can quickly save you.
5.) In other circumstances, it can rise up and down.
?
6.) You'll be here again
You go back to Ice Cap in Sa1 and S3D Blast.
7.) Mega Drive
Its in Sonic 3.
8.) Stop - Sonic Time!
Sonic stops AKA, he is frozen.
9.) You can stock up shortly before.
Theres quite a large bunch of rings in a room right before this fight, I think.
Yes! You win!
#1 - correct
#2 - if you've got a second player playing, they can break you free from the ice, opposed to one player and the Tails AI
#3 - yes
#4 - yes
#5 - when playing as Knuckles, the platfrom underneath Robotnik rises and falls
#6 - yes (although Ice Cap wasn't in 3D Blast; that was Diamond Dust Zone)
#7 - yes
#8 - yes
#9 - yes
Your go!
1.) Unstable footing
2.) Fear the bucket. 
:">
3.) chemistry
Chemical Plant, Sonic 2?
1/ The zone has unstable flooring by chaning up and down, which can throw you into the poisonous goo.
2/ Uhh...
3/ Self explanatory.
Yep.
2.) Fear the Bucket. :">
Eggman's constantly dumping buckets of Goo on you. =D
Okay then!
1/ Very unconventional for a boss...
2/ The fastest thing alive?
3/ Easy to previously obtain rings and an extra life!
Sonic in SA2.
No.
Oh, wait, Metal Sonic in Sonic Heroes?
Nope.
4/ Pre SA.
Pre SA means before Adventure, right? Hmmm....
Metal Sonic in Sonic CD?
Nooope.
5/...what do you mean this isn't the last level? I was sure it was...
Mecha Sonic in S&K3?
I'm not going to give up so easily. 
No.
6) A boss defeated without even having to be hit...?!
1st part boss of Flying Battery act 2?
Eggman just shot a lazer down at you. I don't get the rest....
Nope.
7/ How can someone like you run on such spindly legs?
The Sonic CD boss where you're running on a moving conveyor belt.. *checks GHZ* Quartz Quadrant boss!
Clues that make me think that:
1/ Very unconventional for a boss...
Pretty much all the CD bosses were unconventional.
2/ The fastest thing alive?
Sonic's supposed to be so fast, yet a conveyor belt is able to slow him down that much?
6) A boss defeated without even having to be hit...?!
Yep. Just run and avoid the spikes. =)
Nope. 
8/ Prelude to lightning.
Death Egg boss (1rst part) in Sonic 2?
Flingin' em, now.
No.
*thinks and does some research(been a while since I've played the older games)*
Labrynth Zone Boss from Sonic 1 (Genesis)?
1/ Very unconventional for a boss...
You chase him while avoiding rising water (plus he doesn't have to be hit)
2/ The fastest thing alive?
Dr. Robotnik can outrun Sonic
3/ Easy to previously obtain rings and an extra life!
Theres a room with rings and an extra life
4/ Pre SA.
Sonic 1
5/...what do you mean this isn't the last level? I was sure it was...
In Super Mario (NES), the last level was a maze
(Edit: Oh^^;...apparently the last level of Sonic 1 (Scrap Brain Zone Act 3) looks like Labrynth Zone...*leaves the Mario explanation there anyway, since that is what I first thought of o.o*)
6) A boss defeated without even having to be hit...?!
You dont have to hit him to clear the act
7/ How can someone like you run on such spindly legs?
Dr. Robotnik
8/ Prelude to lightning.
Introduced speed to platform gaming
You're much closer then any of the other guesses, Ari, but still not the boss, I'm afraid.
9/ Master System/Game Gear
Scrap Brain Boss from Sonic 1 GG/SMS!!
It's no boss.. it's a maze!
And the prelude to lightning thing would be because the next level is Sky Base! =D
Ding ding ding! Erika is the winner! 
1/ Very unconventional for a boss...
All he does is run away. 😯
2/ The fastest thing alive?
He runs on his legs and still outpaces Sonic.
3/ Easy to previously obtain rings and an extra life!
You can obtain a life and a shield in the same level, plus some rings iirc.
4/ Pre SA
Sonic 1 MS/GG
5/ ...what do you mean this isn't the last level? I was sure it was...
Scrap Brain is the last level in Sonic 1 for the Megadrive, but is the penultimate level in Sonic 1 MS/GG.
6) A boss defeated without even having to be hit...?!
You dont hit him at all, just chase him.
7/ How can someone like you run on such spindly legs?
Robotnik/Eggman running on his feet. 😯
8/ Prelude to lightning.
The next level is indeed Sky Base, which features a plethora of lightning.
9/ Master System/Game Gear
Sonic 1.
Oh, I loved that boss! The maze before it is awesome. I wonder why I didn't even think of it before.
Well, again, I pass my turn. =)
Dammit.....I'm not going to take it even if I could. I just don't feel like it, ya know?
So the reason for the post was?...
1) The Rev W. Awdry won't be happy with this.
2) Intsa-death (tm)
3) Advance 2 Precursor?
Hmm. Well, Awdry made Thomas the Tank Engine, so I'm thinking it has something to do with trains. Instadeath must mean it has a one-hit kill attack, and Advance 2 probably means that you have to chase it.
...I got nothing. 
Maybe the Train boss from one of the Game Gear games. =o
OMG All you need it a zone name. The correct zone name.
Sunset Park.
Yosh.
Go TTG.
1) Cat claw.
2) Unstainless.
3) Round table.
Because I can.
I'm gonna go with...Chaos 6 from SA.
No.
New clue:
4) Ride the hands.
Is it Rusty Ruin Boss in Sonic 3D? I'll post reasons if right.
You got it, John.
Has it been long enough that I can post a new one?
Crap, I was teh Winner!
Yeah, Free Go.
YIPEE!
1: Laser of DOOM!
2: Ultimate test of speed... until Shadow came around, anyways...
3: This game is quite a gem!
Sonic CD Metal Sonic Fight Race, in Stardust Speedway.
1) The Laser Eggman wields.
2) You race MS.
3) It was on Sonic Gems Collection.
Child's play. =D
I knew it was too easy...
*sigh* You are correct, sir. Besides, this was the first "Name That Boss" I've done, so it was bound to be relatively easy.
By the way, I love all the Yodas in your posts. That "Messed Up, That Is" always makes me laugh!"
It's been nearly a week, so here's a new one to keep us going.
1 - Goth baby?
2 - This sucks.
3 - 3 + 2 = Win?
EDIT: No one wants to take a stab at this?
Is it the Carnival Night Zone one from Sonic 3?
