Evil bosses are the climax of every videogame. It is the stage where you vanquish the most sinister character in the game. For me, the most challenging videogame boss was Dr. Wiley in Megaman. Yeah, it's child's play now, but during that time, he was one heavy SOB. Maybe it was because, before you tackle with him, you had a series of pre-qualifiers first. Well, when I was younger, it took me three days to beat him. How about you? Who was the heaviest evil boss you've fought and defeated?
