And that isn't even the hardest fight.Have fun, Dante certainly doesn't after finding out Nelo's true identity. He can also summon it to spin around him to serve as a makeshift defense against your guns and damage you continuously until the swords break if you are too close to him. And if that isn't enough, he sometimes teleports outside of your reach and attacks you with Summoned Swords, which can rain down Death from Above on you or attack you like a Reverse Shrapnel from an angle. Not only he grows to about 1.5 times his normal size, his moveset (which mirrors yours, plus some) becomes stronger and faster. Vergil) is already a Wake-Up Call Boss when you meet him and the second time you face him is no pushover, but his final fight is a pain. And just to make it all the more tedious, you encounter this boss three times across the game, all toward the endgame.

On the other hand, breaking out of the dimension does give a lot to your Devil Trigger bar and deal a large chunk of damage to the boss. This process will take a large chunk off your health and Devil Trigger bar, and if you allow it to happen more than once, Nightmare might even enter Devil Trigger to increase its strength and regenerate for a short while. To make matters worse, in his blob form it is also capable of swallowing you whole to send you into another dimension where you fight degraded versions of any of the previous bosses (Phantom, Griffon, or even Nelo Angelo). It will also attack you with rapid fire projectiles regardless of what state he is in, which makes him difficult to counter.

The aptly named Nightmare, an amorphous blob that you can't even damage unless you hit the blue crystals scattered around its stage, which will solidify it and allow it to be damaged.

The first Devil May Cry offers a few headaches that will lay demonic beatdowns on your ass, especially in Dante Must Die mode.
