Fatal Finale but literally everyone sings it 

There are indeed 4 or more characters singing at the same time. What I did really was just overlay one of the videos over the other

yeah

It's your vid and the other overlayed

Probably most

since it's a Mashup of two different BETADCIUs, and I know AGgames's has multiple characters reused already in itself, I'd say at least 75% of the characters were used more than once

@@Lilbeamer71 I'd assume like, probably more than that, but yeah, somewhere around those lines
