According to op:
My compilation featuring a bunch of characters from different types of media, such as Video Games, Anime, and Cartoons.

All stages are 3D stages that use the Nightly version's 3D stage mechanisms.

There are some secret characters, both in form of hidden slots and hidden alternate slots in some characters, which i reserved to alternate versions and "sidekicks or sometimes villains" of said character. (Ex: Terry has Garou Terry and Mai Shiranui hidden in his slot)

Big thanks to Meldo for making this pretty cool screenpack However it has a glitch where order select doesn't well, so you can't change your order in tag/simul.

Either way, enjoy this ^-^
