The Ultimate Fan-Fic!

I've always wanted to create a fan fic of some kind, and I've always wanted for it to be EPIC!
I basically want to mix and match a bunch of stuff into one story! The only issue is that for the past two years; I didn't know if it would have been better as a written fan fic story, or if it should be a Video Game!
I wanted to include voice acting, but like hire famous YouTubers to voice their own characters as well as a couple of characters that they voiced in their let's plays (like Jacksepticeye for Flowey and Papryus)! I also wanted to learn a tiny-zy bit of Japanese so I could try to politely ask some of the Japanese voice actors if they were willing to voice some of the anime characters that I wanted to include.
For right now; this is what this is!
I'm going to try to create a fan-fic of some kind! I'll be pulling different characters from all different kind of stories (video games, manga/anime, Dreamworks, Illuminations, Warner Brothers, and Disney)!
There's a reason why I've called this "The Ultimate Fan Fic!"
Please note that I'm only just now working out the kinks for this, and I don't really know what I'm doing with this or where I want to go with this! Some "shipping" would be included in this, but this is still not a lemon! I'll keep things "tame" and it'll be more of a relationship thing (that's opinionated in most cases). Please be nice! Also, if any movie studios sees this (particularly any anime studio creators sees this); please don't sue! I'm a huge fan, and I'm only doing this purely out of fun! Also, I'll use some YouTubers as their own characters in this since they can't voice characters in this! Please enjoy! I'll try to update this weekly (IF I get ideas)! Thanks!
