What is the hardest gaming boss you've encountered?

Only one that currently comes to mind is pirate galaxy christmas event snowman boss.
I knw its not popular game but I cant think of any atm.

Skeletron from Terraria. It is impossible to kill him without having assistance online. Just impossible. Except if you are an addict and you wasted your entire life creating Gravity, Health and Mana potions. Which again is not enough. The freaking thing will flail its arms on your face like dry fish and deal tons of damage on you. It also shots lasers and stuff. You know, lasers, pew pew? It will also spin its head and deal even more tons of damage if it hits you, or if you are dumb enough to fist him face... face... ha ha...

Has everyone already forgot about Taboo from SSBB?

I haven't played that game in quite some time but he still remains the baddest boss I've ever faced.

It took every fiber of Strength in the most hard core videogame players ( Sonic the Hedgehog, Pokemon Trainer Red, Mario, Link, and Snake) to defeat him. I could never defeat him in hard mode T-T

That one. I don't really play many games with bosses, but that's probably the hardest one I ever fought.

Although it isnt hard for the player, its hard for the character Chris. HE HAS TO PUNCH A FRICKING ROCK!!! WHO DOES THAT?!?!!?!?

Ever played Resident evil 5 in coop mode? It' even worse to play as sheva, because she has to hang on a wall and you'd have to keep pressing a button for a very long time.

The rebel flagship from FTL: faster than light (normal mode) i could have the best equipped ship and still be obliterated by missles, drones, and ion cannons

Yukari Yakumo from Touhou 7: Perfect Cherry Blossom, the boss of the Phantasm Stage.
