I do not own this it was made by Smash Bandicoot who is on Soundclound and yt but didn't upload this here. Also this is incredibly offical, 200% Smash Bandicoot is on the Fnf Vs sonic.exe team, yup 200% no joke.

Note from the re-uploader:  if Shadow had better vocals, it would literally be the best part no cap.
