this will be divoted to the lore and more importatly, the weird things about general Vampires.
how is this relevant to Castlevania? only that the entire series is mostly based around killing 1 or 2 if your lucky, LoS made a huge leap by giving a good number of vampires to kill.
Through looking em up and to the mythos, there are breeds of different vampires
OLD Breed - Bat People that take human disguise, example: LoS Vampires, Old Breeds on Infamous 2 Festival of Blood
Old-school Breed, older, more menacing Vampires where all teeth are sharp and physical appearance is always Creepy, example Count Orlock, London after midnight.
This breed Tends to have blood act as youth.
Normal Vampires, typical creatures of the night with fangs, Powers range from super-human abilities to transformation, summon familiars and so much more, no example needed, go watch some movies!
This breed Varies with power, usually stronger gets more abilities.
Dhampir - Basic Half-human born vampires having all the power of a vampire whilst having none of thier weaknesses, examples, D, Alucard, Blade
Sparkly Pricks - Lowest of all breeds, having only basic abilities but use Appearance to track prey, sunlight causes skin to emit small soundless sparks on the skin causing the skin to sparkle. example, AAAAAHAHAHAHAHA!
other lores and breeds and more Castlevania Specific stuff is a group effort.
Flaw with Vampire Control- Vampires have the ability to turn humans into vampires by various ways, BUT if the master vampire is killed within set time of transformation, the human will revert into human form.
LoI "your basically fucked"
using the Conrtol Flaw Leon could have saved Sarah, BUT without the Vampire Killer, Walter could have not been killed, so, sorry leon, it's lose lose for your first wife.
