For me, it was in Last of Us, >!when you walk through the door and get caught in the rope trap, then have to shoot the zombies upside-down.!<

I had to go through that entire animation over and over and over. It made me hate the game. I played a little bit more after finally making it through, but my heart wasn’t in it and I just stopped after a while.

As a kid I beat the vampires in Illusion of Gaia as Will. Didn’t realize you could change.

The snake boss in Nioh 2. My friend kept coming back that day to say, “You haven’t killed it yet?!”

Growing up I struggled for so long on LittleBigPlanet’s Negativitron boss fight, most recently though I spent days struggling with Uncharted 4’s final boss fight (though somehow I had an easier time on Crushing difficulty on my second play through) and Halo 2’s Prophet Boss Fight.

Mushihimesama Futari’s final boss. I felt so proud of myself when I beat it and this is the game that got me into playing Touhou on lunatic mode for fun

Gow Ragnarok. That last Valkyrie.

Final boss of fury

Artorias… hardest one SO FAR

This asshole made me scream in rage and frustration

Lavos. :(

The striders towards the end of Half Life 2 episode 2.

That stupid course in Star Wars Racer where you have to stay on a very narrow ledge. When you fall off you’re relegated to a super long detour and basically have to start over because you have no chance of winning if you fail even once.

So this is dumb but there is a Mummy game, as on the movie, I think on PS2. You could play through as either O’Connell (Brendan Fraser) or Imhotep (he was fun but pretty overpowered). I don’t remember there being a difficulty setting but I could be wrong.

I beat it with Imhotep but never could beat it with O’Connell. I want to say the final boss was the Scorpion King. I tried so many times.

The only thing I can figure is I didn’t load up on as much ammo, grenades, equipment, etc. as possible and never went back to try differently.

The spoiler boss in dead cells.

The boss is not particularly hard but you can only face him after a full run on the max difficulty were you will likely use most of your very limited resources before the bossfight, meaning you can only take a couple hits (at best) before dying.

Well, I’ve never beat Sans from Undertale, but if we’re only counting those we did beat… Maybe it’s Undyne the Undying from the same game. I’m deducing that from the time it took me, but to be honest there’s a boss from another game that came to my mind first. See, neither of these bosses feel “unfairly” hard because you have to go out of your way to pick the hardest route to face them. There was one boss whose hardness seems unfair and bad, that was the third boss from the first Spectrobe game. This was really out of nowhere. The first boss took me a few tries because I wasn’t used to he game mecanics yet, the second was easy, but the third? I had to look up strategies online, make dozens of trips between my ship and the bosse’s location, fighting every mob on the way each time to level my spectrobes up in addition to digging up minerocs to feed them; got them from adult to evolved and finally then I could beat it. After this fight, my spectrobes honestly felt overleveled and every enemy from then on felt super easy.

Worst part is, the plot didn’t even justify this boss to be so hard. It didn’t make it feel important. It wasn’t directly threatening a populated planet, it wasn’t anounced before it appeared, it was just there, in the middle of the jungle. And your mission was to find a diamond. Not an important and powerful item that’s key to saving the galaxy mind you, a dumb simple diamond, of which the only purpose is to be expensive. So why would you, Rallen, of the Nanairo cosmic patrol; charged with protecting the whole solar system, go look for it? Because some rich bastard has crucial information about the krawls and you need this information to go on, but he won’t tell you unless you give him this diamond. BITCH, if there was any logic to the plot, I’d be pointing my canon beam at his head and screaming at him to tell me all he knows or else! How dare a human withhold info necessary to save humanity?

Oh, and if this diamond has no particular power, why is a powerful krawl guarding it? It’s not! It’s just standing on top of it by shear luck, because fuck you.
