Super Smash Bros. Ultimate Ripping Project

[Worldblender]

I got the files from the 10.0 update and I already extracted them, but I can't find Sephiroth anywhere.

Except for Piranha Plant, all of the DLC fighters use (code)names that differ from their actual ones. Do you which files were provided by the 10.0.0 update, or at least a difference between it and older updates? Check if there are any new files in the fighter/ directory that were provided by this update.
