Pretty much all the bosses (except perhaps the first four or five, and of course Wallman) from Castlevania: Order of Ecclesia. Not to just beat, but to beat without taking a single hit yourself. Gravedorcus is a nightmare to dodge when he jumps out of the ground, Albus has those normal bullets that come out of nowhere, Barlowe has that attack in which he flies around the room in a shell of lightning, Blackmore has his punch + fireball combo, Eligor is somehow able to hurt you when you're standing up top of him, Death has those sickles (that actually managed to kill me after I killed him) and Dracula is just Dracula.
Star Ocean 2's final boss Idaelico with limiter off. This was before I had internet, didn't know turned on the hard version of the boss. Think I didn't beat him til I was lvl 140ish, and if i interrupted his I kill you attack "Divine Comedy"(prolly one of my favorite names for a final attack). --- "Men in battle, do not need women.

I saw someone mention Mike Tyson from Mike Tyson's Punch Out. Still can't get past the first round. I may have to try him again on the Wii tonight.
I was surprised nobody mentioned the clone battle on God Mode in God of War. I spent many an hour trying to defend my family only to see versions of Kratos literally tear my body apart. I gave up and only attempted regular and hard mode on GOW II. GOW III is waiting in the wings... --- A PS2 & PS3 backlog?
