Idea for straight rpg Werecreature Vs. Vampires

[Casey the furry one]

Werecreatures have rebelled against their Vampire Overlord over a three hundred years ago. That war still rages today. No mortals know of us and of our war because they are quickly turned on both sides. The year 2006

Rules: you can be human but you will be bitten sooner or later but not of your own accord for the most part. Now for the werecreatures/vampires you can be born/bitten one primary, two secondaries.

Example: all are when you are transformed.
Weredragon/tiger
primary Weredragon, Primary looks scales, wings, fang, snout. Secondary WereTiger, small amount fur allover the body tall
Werebull/Vampire
Primary Werebull,, Primary looks head of more like a bull, horns, tail, secondary Vampire looks two long fangs.
Vampire/Wererabbit
Primary Vampire looks two long fangs, secondary Wererabbit looks light amount of fur, bunny ears, and a cute rabbit nose lol.

Powers for werecreature any ideas

Powers for vampires are able to use their blood as weapons and have different psychic powers.

I need more ideas for this rpg
