Dark Souls- 13
Dark Souls II- 15
Dark Souls III- 19
You've just trekked through Sen's Fortress, a gauntlet of vicious traps, precarious walkways and angry Man-Serpents. You emerge into the roof, and slay the giants hindering your progress. You walk through the fog gate, and standing in front of you is gargantuan suit of armor, blocking to the way to Anor Londo.
You brace yourself for what you presume will be a difficult fight, and you would be right to do so, if you like dancing too close to the edge or neglected to kill the giant above you beforehand. Otherwise, get to hacking at those ankles.
Eventually the Golem will decide he's had enough of standing and wobble like a toddler, until he comes crashing to the ground... and lets you hit him for way too long for a boss. He can also accidentally throw himself off the ledge (a la Dragonrider) but can easily do the same to you if you're not careful.
Spectacle-wise, this fight is awesome, and is up there with the likes of Yhorm the Giant (*SPOILERS* who you won't see for a while) in terms of design. Where the Golem falls short is that there's not really any lore to back it up, other than it being a final test before heading to Anor Londo.
This fight is interesting but not super memorable. He swings his big metal weapon at you and you just stay underneath him hitting away. Fun but nothing spectacular.
46) Old Demon King
Dark Souls III
Tucked away under the Catacombs of Carthus lies the Smouldering Lake, the ruins of Lost Izalith from the first game. Throughout the area you find corpses of demons strewn about and piled up, and you only encounter a couple that are still kicking. Turns out that like the First Flame, the Chaos Flame (which the Witch of Izalith made during her attempt to recreate the original fire) starts to fade after a while, requiring a demon champion to rekindle the fire. The Demon Prince was defeated by Prince Lorian, and as the Chaos Flame faded, demons began to wither and die.
When you enter the Old Demon King's lair, you discover that he is much more deteriorated than the demons you've faced in the past. This doesn't mean he won't put up a fight though. He's got some mean AoE attacks that will really put a damper on your day, and his hammer can deal some good damage. He's got pretty well telegraphed attacks, and he's overall a straightforward boss. He's optional, so you can always come back when you are higher leveled.
Somehow seeing all the corpses of these enemies that thrived and made life so difficult really drives home the plight of the demons. This once powerful race, that once threatened Lord Gwyn himself, has been brought to its knees, and the Old Demon King is just barely hanging in there as it is.
This is a fun fight. Just avoid the big lava smashes. I recommend staying underneath him.
45) Scorpioness Najka
Dark Souls II
After you enter the fog gate past all "Amazing Chest Ahead" messages, you walk into a sand-filled arena with the top half of a woman sticking out of the ground. Once you get over the initial weirdness of this, you run up and hit her, at which point she pops out of the dirt revealing her SCORPION lower body. What is it with Dark Souls and half arachnid ladies?
Anyway, from there the fight doesn't really get particularly difficult if you're smart. Those sorceries will shorten your life pretty quick if they connect, and when she dives under the sand you'd best get to the rock in the middle.
There's some neat lore between her and Manscorpion Tark and how they used to live in peace until she flipped out on him. The two have been locked in a never-ending war with each other for years, unable to overcome the other. Tark requests your help in killing her, as he understands that she is beyond saving at this point. So you get to fight alongside your own scorpion sidekick, which is awesome! Tark also makes a vague reference to the individual who created them, and the implication is that it's none other than Seath the Scaleless.
I actually like this fight a lot. It's not hard, but her burrowing is kinda fun. Overall and enjoyable fight.
44) The Duke's Dear Freja
Dark Souls II
Speaking of arachnids, we have Shelob- I mean, Aragog- I mean, Freja. Whew.
After trekking through the Shaded Woods and Doors of Pharros you stumble upon Brightstone Cove Tseldora, a former mining colony founded by Duke Tseldora. Tseldora developed a strange fascination with spiders, and one in particular named Freja. One day the spiders overran the colony, and the Duke just watched, eerily content. In his private study we find a cage that has been broken, implying something escaped.
At the bottom the colony you discover the lair of the now gigantic Freja and her eight-legged army. She has two faces (and is therefore perfectly symmetrical, which I find fun for some reason), and you have to stay behind her and whack the one that doesn't attack you. You also have to fend off her spider minions as well.
This fight itself is pretty middle of the road, nothing to really complain about but also nothing really to rave on. However, Freja wins the honor of being the only boss to manage to catch me completely off guard. On NG+ and beyond she actually shows up early (before Prowling Magus) and attacks you. I was not expecting this at all, and it freaked me out! I thought my game had glitches or something. I'm pretty sure she killed me there, but it served to remind me that I was indeed playing Dark Souls.
As memorable as this fight is, it's just not up there for me. It gets kinda dull and repetitive. Overall just okay for me.
