25Anderson's Transformation (Hellsing: Ultimate)
Hellsing is one of the most engrossing anime of all time, and watching the ridiculously overpowered Alucard lay waste to his foes is a treat to watch in every sense of the word.
However, this doesn't mean that his foes are pushovers.
Just take the example of Anderson, who used Helena's Nail as
a victory state to match Alucard's power, which is no small feat. Allowing him to become a monster in the vein of his enemy, the mere fact that Alucard considered this nemesis worthy enough to hand him a defeat speaks volumes when it came to Anderson's heightened power.
