What I've taken to affectionately calling "Capcom Difficulty." Two perfect examples: Killer 8 mode of Killer 7 and Dante Must Die mode in Devil May Cry. That mode should've been called "No Seriously Dante, You're Gonna Die" mode. Other offenders are Twisted Metal: Black's "Hard mode", God of War's God Mode, and, of course the boss of Dead Rising's Overtime Mode, especially since they make you fight the WHOLE battle over again if you fail at the last part! Oh and of course any Street Fighter boss, immediately thinking of Akuma and Gil (a boss possessing an undodgeable super that shaves off half your life if BLOCKED AND a ressurrection super)
