19) Smelter Demon
Dark Souls II
The second best boss for DS2 is undoubtedly one of the hardest. I struggled a bunch with the Smelter Demon on my initial run through of the game, but defeating him was nothing short of an amazing feeling.
During the Old Iron King's reign his sorcerer created this guy, and the Smelter Demon killed the king himself. He still remains in the sunken castle, until we take care of him, that is.
This fight is hard for a couple of reasons. First off, his timing is very bizarre. It takes some time to get used to it, and you'll be taking some punishment in the meantime. He also has two deterrents that keep you from being too aggressive: fire that spews from his body, causing your health to constantly dwindle, and a massive (possibly overpowered) AoE attack. He's not unconquerable, but he'll definitely make you work for your victory.
Apparently there's a blue variant in one of the DLCs that's even harder. Makes me shudder just thinking about it.
18) Oceiros, the Consumed King
Dark Souls III
The former king of Lothric became obsessed with producing a worthy heir. His twin sons, Lorian and Lothric, shirked their duties as Lords of Cinder and chose to watch the world rot from a distance, so the game tells us that Oceiros turned to... unspeakable means.
When we find Oceiros in his garden, he has transformed himself into a twisted draconic shape (not unlike that of Seath the Scaleless), and cradles what he claims is his son Ocelot (whom he will not shut up about) when in reality he is holding nothing. He's clearly lost his marbles.
Oceiros then proceeds to attack you in defense of the absent Ocelot, all the while screaming out his name. After his health has taken a bit of a hit, he goes full on batshit crazy and aggressively charges around the room, all the while still shouting at you about his son.
I have one question: if he's not holding a child, then what's making that crying noise during the fight? 0_0
This makes Oceiros one of the more interesting characters in the Souls series, and one I'd like to learn more about. Great fight all around.
17) Yhorm the Giant
Dark Souls III
Yes, Yhorm is an easy fight. Yes, the key to beating him is right in front of you. So why put him so close to the top?
Giant fights in this series mostly suck. Both of them from DS2 got stuck in the bottom half of my list because they were quite boring when compared to others of the series, but not Yhorm.
When you walk in to Yhorm's throne room, and the big guy gets out of his chair and begins lumbering towards you, it's an intense feeling. How am I going to overcome such an insane foe? Any attacks you make barely scratch his health bar, leaving you to wonder how you're going to bring him down.
And that's when you spy the Storm Ruler sitting next to his throne. Grabbing this legendary blade and utilizing its special ability demolishes Yhorm's health bar and literally brings him to his knees. Do 4 or 5 of these and you'll win. He will make you work for it and hits like a truck, so just don't get greedy.
Yhorm's story is kind of a sad one. He was the descendant of a great conquerer (Wolnir?) and was asked by his people to rule over them. While he agreed, the stigma of being a giant was all too apparent as they were insincere in their love and respect for him. To overcome this, he gave them a Storm Ruler in order to gain their trust.
The Profaned Flame was formed during Yhorm's reign, which scorched his capital and burned his people. The Giant used his powerful soul to link the First Flame and save his people. Before this, he gave his dear friend Siegward another Storm Ruler to end his suffering should he ever return.
And if you follow Siegward's questline, he will show up alongside you to honor his friend's final request. Truly a bittersweet end to an amazing fight.
But there's still two more Lords of Cinder we haven't covered yet...
16) The Pursuer
Dark Souls II
Time for my pick for the best boss in the second game!
So you're trekking through the ruins near the Forest of Fallen Giants, and you climb up on top of a flat roofed building. A giant bird flies overhead and drops in an armor-clad warrior with a large sword and shield, creating the coolest boss intro ever.
