In that episode of rebels the loth-wolf is part of a bigger part of the Force, the light and the dark. It kept on saying Kanan's real name his last name, this made me though for a while, is Kanan that Big loth-wolf when Kanan died? I looked more into it and was saying it must be Kanan or part of him I'm just guessing if it was Kanan,

What do you think what the Wolf really is? Comment down below please
