I might have to register my vote towards Sodom from Final Fight. This guy's so tough, he's the only boss in the game that doesn't need assistance from the lower ranks of Mad Gear. That, and it's a real bitch getting tackled by him. It's impossible to avoid sometimes. Also, Rolento is an excellent boss. He might not have the most life, but DAMN, is he hard to touch! Then there's his Minesweeper, where he jumps onto the girder in the background and rolls, dropping several grenades at you in the process. What rocks about these two is that they were faithfully translated to the Street Fighter Alpha series, and they're two of my favorite characters in that game. Any memorable BEU fights you have to share?
