How am I the only one complaining about the rogue legacy neo bosses?

As my first souls game, the gargoyles at the rough top from dark souls had me in the fetal position, crying in the corner. It took me at least 3 days to take (playing about 2 hours each) to finally take them down. It was a rental so I didn't get far enough to encounter another super tough boss.

Sephiroth in Kingdom Hearts was also hard as shit. It took a lot of grinding and failing to finally topple that mother fucker.

Maybe? I know Bad Girl had an OHKO. Jeane was the one with low tells, who would counter ANY attempt to throw her, and just fought at a lightning-fast pace.

No I don't think so... the one before her was Bad Girl (with the frilly dress and the baseball bat) who has a sneaky insta-death as one of her moves once she is down to 1/3rd health. She suddenly flops to the floor and cries, sometimes for real but usually fake crying, if you go near her when it's fake she will kill you.

Jeane is just fast and well defended, she only has a few openings and they don't last long so you can't do much damage at once.... also if I remember correctly she can't be caught out by sidestepping her (which with most enemies gives a much longer opening to hit as well as opportunities for the powerful moves or wrestling throws)

I agree on this.

I'm adding my personal hardest, Flemeth from DA:O, Ruby Weapon from FF7 and Sephiroth from Kingdom Hearts.

Hitoshura on Digital Devil Saga. For an RPG boss, Hitoshura isn't just hard, he's cheap and also takes around two hours or more to beat, something I've never done and never plan on doing, especially after seeing what you have to do. Too long, memorization bullshit, good chance at randomly dying, etc.

Sturm on Advance Wars. The battle is ridiculous, and if you screw up once consider yourself dead. Throughout the entire battle you also have to trick the enemy into using meteor on a group of useless allies.

The chess board on DMC3 Dante Must Die mode without Super Dante and Nevan.

Ozma from FF IX. So many days of grinding on sheep to beat that guy.
Aside from that I would say, though I can't remember in detail, various bosses from any Mega Man game.

I'm sorry but unless you're playing on mythic difficulty I have to say no.

Hmmm probably not the toughest, but it's the only one I can think of right now.

Penance in Final Fantasy X.

Lol, funny thing is, Didact is just a QTE boss. You don't even really fight him
