Once upon a time, in another timeline, there existed a planet, where only vampires lived, and alongside them were the animals who were also vampires.
Like, Ultra Sonic Vampire Bats, Super Strong Bloodsucking Spider, Ultra Fast-Moving Bat-Winged Vampire Rats, etc.
But, all of them were the same.
They had the same blood as a vampire and had the powers and abilities that came with their specific race.
For example, Ultra Sonic Vampire Bats could emit sound waves that were capable of killing humans.
As for the other monsters, their powers and abilities were different but were all identical at the same.
Even the trees, plants, and flowers were the same.
They all had vampire blood and could live for eternity.
Even their birth cycle was different.
It would at least take a hundred years for sure to give birth to a baby.
And, this was true for the vampires, too.
