Ansem in his final stage in Kingdom Hearts 1. HES SO DIFFICULT FOR NO REASON, took me like 5 hours straight to beat on my first playthrough-
also Gizamalukein final fantasy IX, its such a massive difficulty spike that requires like 2-3 hours of grinding when it just shouldnt be that hard of a fight-
Jingu Kyohei's fight from Yakuza Kiwami is a crime against humanity I swear.
This guy shoots at you with his gun and throws grenades from a distance while his two bodyguards keep you busy and he runs away should you get any closer to him giving you little to no breathing room to do anything.
and just when you think those bodyguards are done with they get back up in the second phase and come back stronger its just ughghgh
