Number one was easy as hell to spam with missiles. The hardest one I had a tough time with was Prisoner No. B-24715
The nameless king in dark souls
Why do you think this is though? Why are games designed so that the hardest boss comes before the end?
Is it that your skills are not as honed when you come across earlier bosses, and that makes them harder?
Are they designed that way on purpose, as a way as making the player feel like a badass?
Is it down to poor balancing?
Considering how few people beat games these days, why add the hardest part before the end?
FF7, though, yeah, definitely NOT the hardest at all.
Final Fantasy back then was known for this (i remember that Omega weapon fight in FVIII very well...also these Dark Aoens and Penance in FF X).
P3P Nyx is such a cakewalk. I was disappointed TBH.
Breath of the Wild is probably the best recent example.
As far as older games go, Tales of Symphonia is one that comes to mind.
Lorinthia (I think that was her name ? ) in Xenoblade Chronicles, I wiped so many times on her and then I proceeded to utterly destroy the joke that was the final boss of that game.
Those are all not mandatory at all.
This is Spikey Tiger from Secret of Mana, the third boss you fight. He is one of the single hardest bosses in the game for several reasons.
He is the last boss you fight before getting access to magic. He however has powerful spells. And while the bosses prior to him have spells too, they are not particularly strong.
He also has an arena that allows him to go to spots where you cannot hit him (where magic would help tremendously!!), and has an attack that has him curl into a ball and roll all over the arena.
He also deals massive damage with his attacks.
And then there's this asshole:
This guy has an AoE attack that paralyzes and also deals a lot of damage (plus poison, yay!). This is Lufia 2 btw.
Persona 5. The obligatory Velvet Room attendant fight is always very hard.
Justine and Caroline can Baton Pass, at one point can hit literally any weakness you have, and even have an All Out Attack complete with Finisher Animation.
"Don't get cocky."
I love that it's not only hard in a bigger numbers kind of way, you actually need to understand and exploit the game to beat them.
There's also the Reaper wandering Mementos, though there are some funny ways to deal with it.
Bloodborne
Gehrman was an infinitly more challenging and satisfying fight than the Moon Presence
Technically speaking both of those bosses are optional.
