I am Soul sonic a ghostly figure that sings along Sink in his eponymous song. It is unclear what this Sonic is or if he is the same person as Sink. Even his name is unknown. Theories circulate that this Sonic is Sink's inner consciousness keeping him "alive." Another theory suggests that it's Sink's soul calling out to anyone who can hear him. Another possibility is that this Sonic is Sink's "sheer willpower", that keeps Sink alive underwater, much to his dismay. Gender:male Species:hedgehog
