The End is NOT hard. It's just a (potentially) very long sequence.

Yeah hes not so hard but it takes some time to kill him...
Thermal Googles, NVG and that Sound capturing system are good when he takes a nap =DD

Try any Metal Slug boss on a "no life lost" run.

Fine, Rocket Racer in Lego Racers.

Sephiroth on Kingdom Hearts. At level 60, far enough to beat the game, you can die from literally 2 hits from him. His last form also has the annoying ability to insta-kill you, and his weapon has probably the longest reach of the game. Also, you fight alone, no party members to heal you. It's like the developers purposely punish you for buying the game.

Sephiroth wasn't THAT hard. I'm not saying it wasn't a difficult fight, but after a lot of trial and error killing him is quite possible. As long as you have a decent weapon you can just attack him over and over then run away and repeat.

Tartarus at the end of Halo 2 was crazy hard on Legendary. I got pretty damn good at that game and I still couldn't finish the game on Legendary.

i always found the final boss Majoras Mask is pretty tough.
I had some issues with Zues in the end of God of War 3. (tho most of the fight was quick time events)
Lou was an a$$hole on Expert in GH3.

Hands down the hardest boss fight I've ever done was Sephiroth from FFVII. I remember all to well fighting this dude for nearly 30 minutes at a time only to lose to one of those lengthy summons he did. This is closely followed by Emerald and Ruby weapon from the same game. I can't help it I guess, I loved that game lol.

That, just one mistake and you lose the damn race, I remember well having to restart the race like 25 times or so until I finally beat him. Either he ninja's the green block at the beginning or you mess up somewhere and you'll never catch up again.

Alma from Ninja gaiden black was very tough, especially on hard where she summons fiends to help her out.
I strangely enough also had a lot of trouble with the second phase of the final boss in Wolfenstein (The new one), he just keeps teleporting around really fast, always knows where to find you and then uses vulcans to kill you VERY fast, did I mention those can go through walls as well?

I played FFVII as well, I found sephiroth pretty hard at first but now he's not a real problem anymore. I think Zeromus from FFIV was a lot harder, but that would still be dependant of how high-leveled your characters are.

Kill him with banshee. Easy mode.

The End is the easiest boss ever. Save, turn of console for a fortnight, when you get back, he's already dead.
