I spent months writting and designing a story and theconcept about a character reaching some kind of divine power that was so rare even among gods... I had everything even the design more or less ready.
Months later I saw the Ultra Instict on TV.
It wasn't a 1:1 representation but I was amazed by how close it was, if I had to put a scale I would say that 8 out of 10 things were the same as how I writted it, I was filled with joy watching the whole thing being done in DB and made me think about how small the world is.
