Imma do a thing. Gonna explain what led me to doing the thing.
I've been trying to come up with a set of mechanics for werewolves which I may or may not create. I'd come up with a few ideas but nothing solid so I decided to take a break and instead think about how I could implement becoming a Super Saiyan, purely for the fun of thinking about it - I had no intention of actually coming up with anything, I swear. Mostly I was thinking about how it could be justified in a world where the Final Form trait already exists. I honestly didn't expect to come up with anything worthwhile and I'm both surprised and proud that I did.
I'm basically trying to say that the idea did indeed branch from a pre-existing idea, it's still its own unique and original idea. Example: shows like Naruto, Bleach, TTGL, etc. have super modes/final forms yet they can all be considered original simply by the way they provided their own unique takes on the idea, despite said idea being done already and despite said idea practically originating from a single source. (Dragon Ball Z)
Disclaimer said and done, it's time for me to type up what I came up with in the IC thread.
EDIT: I have to admit, while I claim that the idea I came up with is suitably original on its own, its name is completely stolen from another popular Bay12 forum game ENTIRELY ORIGINAL AND INSPIRED BY VARIOUS DIFFERENT SOURCES OF MEDIA, OF COURSE!
