On the spur of the moment, I decided to go on YouTube to see if I could find any videos of the Z-Moves introduced in the new Pokemon Sun and Moon games. The following video showcases every known Z-Move in the game, including a couple that haven't been officially revealed.
Admittedly, I mainly posted this video for myself. I thought it might be nice to have something to reference in case I decide to use some Z-Moves in some of my Pokemon fanfics. I apologize if this video isn't of the best quality. There's also a good chance that this video might be taken down. If that happens, please let me know so I can delete this post and maybe find another video.
