Hellsing, the corporation dedicated for slaying vampires racks number 6 on our list. I will be the first to admit that the story behind our protagonist Arikado or Alucard is waaaay burned out, the only True Alucard in my mind will forever be Adrian Tepes Alucard from Castlevania. So Hellsing is a corporation that was formerly known as the Holy order of the protestant knights Founded by Abraham Van Helsing, so they had enslaved a vampire, a real powerful one to hunt other vampires, but after the end of the second world war everyone decided that keep using Alucard as a weapon was far to dangerous and so they locked him in a dungeon in the Hellsing mansion. By a twist of fate Integra, a child found him and took up the mantle of the leader of the Hellsing organization with the help of Alucard.
|A vampire with big knockers|
A police officer found a church filled with lesser vampires and was fatally wounded when Alucard came and destroyed every vampire there with his trusty fire weapons made out of a blessed silver cross from the vatican (Cool stuff actually) So Alucard asks the dying police officer Seras Victoria if she wishes to die or be born again a vampire, she chooses the later and so becomes Alucards childe and so the vampire hunting begins.
My only complaint in this series is that our hero Alucard is WAAAAAAAY overpowered he can be put into a blender and he can regenerate again from any kind of damage but it is a good series, for an anime now a days thats saying alot.
