The Shredder at the end of TMNT The Arcade game. It would cost you 6 bucks worth of quarters to beat him solo.
What about contra for ps...begins with a difficult boss and only gets worse...cheers to breaking controllers
Mike Tyson from Tysons Punch out. One hit knock downs, go down twice in one round and you're done. That's hard. And as for hard clasic games... well just about all of them were hard because you always started off with three lives. I don't really recall beating more then a handful of games on the NES. and those were the days that I gamed all summer long.
The last boss in Blue Shadow(NES)...Could never beat him Yeah Ruby weapon is though nut..I remember i beated him(After countless efforts) with Mime,W-Summon and Knights of the Round Table materia and Mega-All materia linked with healing between the attacks
The three dragons in Etrian Odyssey. Without the Anti spells, you will be dead before the first turn is up.
