Cooler Classic Voice
Just sharing a personal mod, since release, I always felt Cooler's voice would sound much better with his classic lower pitch voice. So I dove in the files and lowered the pitch on all his lines. He sound much more familiar to me now.
I also did minor touch up on some lines that did sound too much out of character to me even pitched down, like his controversial "gyahh!" yell on one his special moves, he now yells "die!" ;)
Just place the .pak files in your mods folder.
