Hardest Super Mario Galaxy Levels / Bosses

The Top Ten

1 Grandmaster Galaxy - The Perfect Run - SMG2

This didn't take me too long, but that's only because I had a friend help me with it, freeze and kill enemies and stuff, you know... lmao. I can't even complete it on my own (not as of right now anyways). If I tried, I would certainly be as triggered as some of you right now. I haven't beat it but once, and haven't played it since that time. by the way, lol that Geometry Dash comment! That's my favorite game, but I don't really know anyone who plays it but me! Now I don't feel like such a "black sheep" lol. The new hardest (rated) level in the game is Sonic Wave, the hardest possible Nine Circles level in the game, but some pretty crazy demons are coming (The Fearless, 211, Freedom Dive, Fusion Z, Bloodlust, God Eater, Ragnarok, River Styx, Blade of Justice, etc...)

This took me 100 attempts. but geometry dash is obviously harder because in geometry dash's hardest level cataclysm , it took me 20000! Attempts

Geometry Dash's hardest level is "Cataclysm"... Are you taking a piss? I bet you haven't heard impossible levels like Silent Circles, SlaughterHouse, etc. - Doge4lifeGaming

I lost 80 lives! I played this one level for two three hour periods! I rage-Quit a year ago and never came back

Took me two weeks to do that level.

2 Melty Molten Galaxy - The Sinking Lava Spire Daredevil Run - SMG

Satan himself created this monstrosity. It's one of the few levels preventing me from getting Luigi.

Almost impossible. I feel this slighty harder that the perfect run, but is still not harder though. this is indeed the star where many players stopped playing. I mean, seriously. you have to do the star that is easy to get hit on, without getting hit. and the worst part is, without checkpoints. YES, WiTHOUT CHECKPOINTS! This took me like 4-6 hours the first time with Mario. and it took longer (6-7 hours) with luigi.

Probably the hardest star in the game, together with Bouldergeist Daredevil Run and Dreadnought Purple Coin Comet. I'm always failing on the last part; gotta start all over again. Thanks, game! - Bokito

While doing it, I could tell that this level was hard but it just wasn't that hard for me and I beat it on my second try in normal and daredevil.

3 Grandmaster Galaxy - The Ultimate Test - SMG2

If you know what the perfect run is,you have to do that level,exept not with the daredevil - Nateawesomeness

4 Boss Blitz Galaxy - Throwback Throwdown Speed Run - SMG2

This is the ONLY level in the galaxy games that I had to rage quit. Every time I play, I have 3 and a half minutes left when I get to bouldergeist. Yet somehow, my time is always drained by the time I beat him, leaving me about 30 seconds each time to get to the last boss and get the star. All I ever needed was to beat bouldergeist faster, but it just doesn't happen.

Unlike most people time is not an issue for me. I can easily get to Fiery Dino Piranha with a minute left but the problem is, I just can't beat him. He's too difficult. I think that the thing that most people have with Fiery Dino Piranha is that either they run out of time on his final stage or die. This level is the reason that I haven't played this game in forever.

The time limit is the problem. I can beat Dino Piranha and King Kaliente in a minute. Major Burrow is always hard for me, and Bouldergeist is time consuming. Fiery Dino Piranha, you just need to be calm which can get hard with everything going on. Overall, a fun and challenging mission. Favorite level!

I HATE this level. I still haven't finished it and I have spent 24 lives on it!

5 Sling Pod Galaxy - A Very Sticky Situation - SMG

This is harder than some higher up levels like melty molten galaxy sinking spire.

! I had SO MUCH TROUBLE with this stupid star!

This reminds me of angry birds,but 100 times harder - Nateawesomeness

This is sooo easy why is it so high on the list? - Bokito

6 Bouldergeist Daredevil Run (Super Mario Galaxy)

Why is this one so low on the list? I found it very difficult to complete! Actually, it took me 20 tries to complete it without playing Daredevil mode. To my own surprise, I then cleared the daredevil run with my second try, dying the first time for mysterious reasons (I didn't know why I died). But it was still very hard. - Bokito

I can see how luigi I got captured by it

7 Space Junk Galaxy - Purple Coin Spacewalk - SMG

This is only hard if you are playing as Luigi.

This isn't hard,exept it's kind of hard if your luigi - Nateawesomeness

This isn't so hard, but you should be careful. Got the 100 coins with like half a minute left, then fell off... so dumb to do. :( but if you don't, it's easy. - Bokito

8 Battle Belt Galaxy - Mini-Planet Daredevil Run - SMG2

This has checkpoints which ruined the chance of being hard - Nateawesomeness

It even has checkpoints.

And how is this hard

I don't find this hard!

9 Deep Dark Galaxy Underground Ghost Ship Daredevil - SMG1
10 Toy Time Galaxy - Luigi's Purple Coins - SMG

Didn't realize at first that there are more then 100 coins and so spent waaay too much time on it. - TheInsomniac

Dude, it's not purple green lava, it's dark matter

Should be upper on the list.

Didn't find this as hard.but still kind of hard,I felt like a god when I did this in my THIRD ATTEMPT - Nateawesomeness

The Contenders

11 Shiverburn Galaxy - Green Star 3 - SMG2

This one really needs to be higher on the list! This star is the only one I've legitimately gotten angry over. A star where you can't get hit, can't spin more than twice after getting the cloud mushroom, and you can't really use checkpoints? Bull.

This star can go die

Oh,this star - Nateawesomeness

12 Bowser's Dark Matter Plant - Darkness on the Horizon - SMG

The cruise is a bit confusing but besides that, EASY

Not hard at all.

The cruise can be confusing - Nateawesomeness

Damn I hate this level

13 Melty Monster Galaxy - Green Star 1 - SMG2
14 Bugaboom - SMG/2

How is he hard he is only in world one/2

15 Stone Cyclone Galaxy/ Beach Bowl Galaxy - SMG/2

Took ages to find the perfect strategy.

16 Return Of Luigi's Purple Coins - SMG2

I vote for this one. Though The Perfect Run is obviously the hardest, I don't consider it a worthy option to vote for because it is purposefully the hardest. I had so many attempts at this before completing it anyways...

This deserves to be higher than Luigi's Purple Coins. Here, you're still collecting Purple Coins, But now, you're also given a Time Limit and are being chased by Cosmic Clones.

This should be WAY higher!

17 Kingfin - SMG
18 Purple Coins In the Bone Pen - SMG

This isn't hard if you know this trick: whatever happens, try to keep moving, and fast where possible. Don't care about routes you need to take, you'll always make a mess somewhere. I usually get between 5 and 10 seconds every time I play it. - Bokito

Duh, I beat this level with 16 seconds to spare. The trick is not to look at how much time you have left or how many purple coins you have left.

I always get this star with 1-5 seconds left!

19 Luigi's Purple Coins - SMG

Can be quite challenging, but there are way more coins on the level than you need, so try to leave some spaces open for the way back. - Bokito

So annoying actually thought it was gonna be fun before I started the level because toy time galaxy is fun but there's a trick there-there a more than 100 purple coins
Hope this helps people that are struggling with this the star

It's so hard, it's on the list twice! - TheYoshiOverlord

I hard it's on here twice - TheKirbyCreeper999

20 Purple Coins On the Summit - SMG

Hilariously easy. But it's so damn time consuming. You missed that coin on top of the mountain? Climb it again, sonny boy. It takes me 15-20 minutes to complete. And that's average time!

Very hard level, purple coins in insane places, and if you die, (Which probably will happen), you have to start the WHOLE level over again.

21 Bouldergeist - SMG/2

Bouldergeist is a super hard boss, especially in the daredevil run.

The daredevil was the hardest on my first try

3rd hardest Mario boss

22 Fiery Dino Piranha - SMG/2

Who thought nature could be so fierce?

2nd hardest Mario boss I fought

Argh! I touched him by mistake once and died when I was almost there!

23 Fiery Gobblegut - SMG2

Oh god if the normal gobble gut is hard enough why not make fiery gobble gut THE HARDEST BOSS IN THE GAME and at least he is not required and is a hidden boss in battle belt galaxy THANK GOODNESS HE IS NOT REQUIRED

I can't defeat it and I am pro at this game

I have 119 stars. JUST THIS ONE!

Very hard boss. Useually I beat bosses on my first try, and this made me beat it on my foruth
