Anyway, with that said, yes I'd say I'm creative. I tend to express it through writing, though I haven't exactly written much yet but that's because I tend to like having the vast majority of projects planned before I start most projects. So, I've written down plenty of information regarding most of what I've thought off but I haven't actually composed the stories yet. I have a general overview of several different long running battle shonen series I'm working on. This encompasses characters, battle system and all that comes with that and the individual story arcs (all have at least five, most are in the double digit, the longest has thirty-five arcs planned [as in, I know what happens in them] with another batch on the way) and despite a few elements overlapping, all of them are pretty distinctive from one another. Granted, most of the plot details aren't written down, my brain forces me to go over something multiple times so I remember most of the stuff in each offhand.
Also working on a One Piece elsewhere fanfiction (which essentially means, it takes place in the same world as OP but focuses entirely on original characters and original stories [OP is perfect for this type of fanfiction, since it's world is massive and Devil Fruits allow you to come up with some truly original powers]). Since this will actually be posted I have a lot more written down on this. Currently has thirty-six arcs but I'm thinking of cutting it down a bit and I've come up with 136 different original characters. Some are pretty basic but I think several show off my creativity more a lot more (and then there are those that are just downright Blue but meh, it fits the world. Also, my friends doing his own OP elsewhere fic (they'll be a few crossover arcs) and I've come up with a few Paramecia's for him to use (for those unaware and for whatever reason actually reading this, Paramecia are pretty much the free-reign powers of the series, endless possibilities there). Finally (on this note), I came up with a certain system for an arc that is pretty complex and really unique that I'm actually really proud of and will totally use it if I ever become a competent drawer and learn Japanese and could actually work on my own manga (that's never going to happen).
Also currently working on a BTB for another site with another friend (we have our big four we will both be represented but otherwise both our brands will remain isolated and function separately outside of the occasionally program we might want to run) and I'm kinda using that to use several very out there and unique ideas for a wrestling federation (okay, that's an assumption since I only watch WWE but I'm positive that at least one of my ideas is unique). Like the top quote applies, I have influences for some of my ideas here but I've incorporated them into a wrestling enviroment and I think it's going to work greatly (at least for a BTB) .
*Edit*
Forgot, I have a ton of video game ideas and a few song ones as well. Not going to expand upon on those in the slightest though.
: I would love to be a book writer as well.
