To make it short: I‘ve been having this idea stuck in my head for 11 years now, started drawing 9 years ago for the sake of it and kinda started my journey as an artist from there.
Long story: Like, as we were as 10 year olds, my friends and I would always role-play during breaks in school, but not as characters from shows - no, no, we wanted to spice it up - we role-played as self-inserts. Looking back, it‘s actually more funny to me than cringe, because that‘s how I came up with my main OC two years later and over the years of developing the plot and worldbuilding of my project Sky Diver, she just became just another character in that story, though she does serve the purpose of one of the protagonists after all. The project stuck with me for so long that it kind of became my little escape, but also helped me grow in a way, since I started imagining how the characters in the story would react to things that happened to me and how they would resolve things.
However, that‘s not the core aspect of it though since, as I stated in the beginning, the story‘s focus is on the concept of crossovers, which makes it basically a fanfiction, but I was always fascinated by the basic concept of characters from very different universes meeting each other - even more exciting how it would be to be a part of it or just see what happens, if such worlds would interact even with our own. And shonen anime. Anime in general, I even wanted to animate stuff for it at one point, until I finally decided to reboot the comic project because animation costs me too much blood, sweat and tears to do 
I think the most prominent inspiration until now - not inclusions, like with certain series that made their first appearance at the end of the most recent episode - were anime like Gurren Lagann & Kill la Kill, but also JoJo‘s Bizarre Adventure.
Why the last one? When I first wrote the whole project out in 2015-2018 (as a fanfiction of course), I wrote 4 sagas in total with different protagonists, which could be standalone, but also tie into each other and the protagonists are all related, actually 
Right now, I can‘t wait to share the rebooted and definitive version of the story and the many adventures of the ragtag group that calls themselves „the team Sky Diver“! :3
