For that matter, the entire final battle against Vergil. Dramatic Thunder, a tricky enemy Dante's size, teleportation, and a Doppleganger Attack. On the harder difficulties, you feel like a badass for winning.
Not just any Dramatic Thunder. The fight starts with the skies perfectly clear. The thunder clouds build from the ground up at the edge of the arena. The fight was so hardcore it generated a thunderstorm.
Dante gets his white hair. After all the criticism about the new Dante's character design, the fans got their wish.
The ending of Vergil's Downfall. An army of demons approaches Vergil, ready to tear him apart. Vergil, fresh from destroying the last remnants of doubt and goodness in his heart, turns around and his eyes briefly flash red as he prepares to draw his sword. The demons are so cowed by his new terrifying power and resolve that they immediately bow before him.
