Final boss fight with Dracula and the good ending.

Before fighting Dracula you should have 99.80% (100% in all maps and 96% in Dracula's Castle), then after you clear the game you'll have 100% map completion.

Dracula's first form is pretty easy, it's the same as every other game almost, Rapidus Fio can dodge the fireballs and ducking/double jumping keeps you safe from the meteors. If you're fast, using Rapidus Fio and going through him when his bats appear can get you behind him, and you can attack him while he's facing the other way. Just don't try this after he teleports or he'll smack you with his cape.

For his fatal ray, get near him, and you can attack without getting hit, being in front of him gives you more room.

For his second form it gets tricky, he'll summon bats (duck down near him to avoid), wolves (attack them to get rid of them), and his destruction ray (go back and forth to dodge), and a kick if you get too close. Individually these are easy to dodge, it's just his soul steal can catch you off guard, I had such a hard time dodging it when he combined it with his other attacks, which individually are easy to deal with, so I smoked him with the light/darkness union.

Also, as the dialogue implies, use the Dominus Union to finish off Dracula, unless you want to be a robot or fly in the upper right corner forever...
