Hardest Super Mario Galaxy Levels / Bosses

The Top Ten
Grandmaster Galaxy - The Perfect Run (Super Mario Galaxy 2)

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

I don't have SMG2, but I think this does deserve to be #1 on the list. It is sooo hard - you may not make a single mistake, it's sooo difficult.

This level makes me want to kill someone. It is definitely the hardest Mario level EV-ER.

Melty Molten Galaxy - The Sinking Lava Spire Daredevil Run (Super Mario Galaxy)

Ah yes, the famed sinking lava spire run. I have died so many times here, and this is the perfect run of SMG1. I found this harder than the perfect run of SMG2, and that's because of how insane the progression is.

After dying for a while, you start rushing through the volcano planet and make more mistakes. When you finally get to the pull star bit, you slowly lose patience and may lose timing. Then, the planet after that is the worst bit. All those lava cinders everywhere, the location of the star chips, and the launch star are way too difficult. It takes extreme planning and precision to do such a gauntlet.

Then, the buildup to the spire is really stressful. By the point you reach the sideways sinking platforms, the Wii remote is already suffering from your sweat. The lava spire itself is the hardest part of all of it. You want to run quickly, but the boulders, lava cinders, distracting star bits, and one-ups, along with the difficult long jumps, create a recipe for difficulty. Absolutely grueling.

This is also my favorite comet mission in both games, though. On my first playthrough here, I died at least 100 times.

Grandmaster Galaxy - The Ultimate Test (Super Mario Galaxy 2)
Boss Blitz Galaxy - Throwback Throwdown Speed Run (Super Mario Galaxy 2)

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 the issue most people have with Fiery Dino Piranha is that they either run out of time on his final stage or die. This level is the reason I haven't played this game in forever.

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.

Sling Pod Galaxy - A Very Sticky Situation (Super Mario Galaxy)

This is harder than some higher-up levels like Melty Molten Galaxy's Sinking Spire.

Space Junk Galaxy - Purple Coin Spacewalk (Super Mario Galaxy)

This is only hard if you are playing as Luigi.

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 on my second try, dying the first time for mysterious reasons (I didn't know why I died). But it was still very hard.

Battle Belt Galaxy - Mini-Planet Daredevil Run (Super Mario Galaxy 2)
Deep Dark Galaxy - Underground Ghost Ship Daredevil Run (Super Mario Galaxy)

I never had an issue with Kamella. She was always a nice boss with a cool aesthetic and concept. That was until this. I didn't even realize that the green shells can actually kill you if you don't spin quickly enough until now. Kamella also teleports a lot better during this fight compared to the other two variants. She'll teleport behind you, and you'll get touched and die, or she'll teleport when you have the perfect chance to get her.

The real difficulty comes from the final section when she moves up to her own platform. Yeah, I don't need to describe it - it's just pure anxiety. If I have advice for you, just kill the Kameks quickly enough before getting assaulted. Definitely top 10 hardest missions in this game, but definitely not the hardest too.

Toy Time Galaxy - Luigi's Purple Coins (Super Mario Galaxy)

This should be at the top of the list. You have to be perfect to finish this. Even without the ridiculous time limit, this would be hard.

It can be quite challenging, but there are way more coins in the level than you need, so try to leave some spaces open for the way back.

ARGH! You have to get 100 purple coins while avoiding that OHKO purple-green lava and the disappearing and rotating platforms, and the level is TIMED! But that's not enough. In SMG2, the level has CLONES too!

The Newcomers

? Silver Stars - The Cyclone Stone (Super Mario Galaxy 2)

This gave me the most trouble when I was 8. I'm 13 now, and it doesn't give me trouble anymore, but it should at least be on the list.

? Bowser Jr.'s Mega Hammer Slammer (Super Mario Galaxy 2)

I had so much trouble with this. It took me 20 tries to beat this galaxy.

The Contenders
Shiverburn Galaxy - Green Star 3 (Super Mario Galaxy 2)

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.

Bowser's Dark Matter Plant - Darkness on the Horizon (Super Mario Galaxy)
Melty Monster Galaxy - Green Star 1 (Super Mario Galaxy 2)
Bugaboom (Super Mario Galaxy / Super Mario Galaxy 2)
Stone Cyclone Galaxy (Super Mario Galaxy)

It took ages to find the perfect strategy.

Return of Luigi's Purple Coins (Super Mario Galaxy 2)

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 purposely the hardest. I had so many attempts at this before completing it anyway.

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.

Kingfin (Super Mario Galaxy)
Purple Coins in the Bone Pen (Super Mario Galaxy)

There's no way you've done this on your very first try. After a while, it becomes pretty easy, but it took me 5-6 tries to make a good strategy. The real issue is the timer. Other than that, it is somewhat entertaining and uses the purple coins well. The second hardest purple coin mission after Dreadnought's.

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

Major Burrows' Daredevil Run - Gusty Garden Galaxy (Super Mario Galaxy)
Megaleg (Super Mario Galaxy)
Sweet Sweet Galaxy - Rocky Road (Super Mario Galaxy)

Nowadays, this is on the easier side, but on my first playthrough, it was extremely difficult. It also has some of the best level design in the entire series. The three concepts mashed into one create the best one-star galaxy in the entire game. I appreciate the challenge, and the checkpoints were really helpful.

If you don't think this is hard enough, try playing without spinning or long jumping/side-flipping/triple jumping. Just use the nunchuk and the normal jump. It is really difficult. Good luck!

Rollodillo (Super Mario Galaxy 2)
Mecha Bowser (Super Mario Galaxy)
Purple Coins on the Summit (Super Mario Galaxy)

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

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