Sonic's Fear

Sonic's Fear of Water

Since Sonic 1's Labyrinth Zone, Sonic's distaste for water turned into a fear.

Though early canon showed that Sonic disliked water, it was not until Sonic Underground that it completely turned into a fear. Though Sonic "faced his fear" in "The Deepest Fear," his persistent hydrophobia would be a a reoccurring gag through out.

Though Sonic X ignored many elements of "western canon," Sonic's fear was shown in the very first episode. Like in Underground, Sonic's fear caused him to act off, perhaps moreso. Sonic sort-of faces his fear in "Cruise Blues," but not before doing everything in his power to try and get away from the situation. This was also a reoccurring gag throughout this series.

The games never officially addressed whether Sonic had a fear. He's faced many water levels, but it's obvious that he can not swim. Some of the Olympic games have Sonic in a life-vest.

Again, Sonic was shown weary of water Archie comics, notably in the story arc "Waves of Change." Still, he was portrayed as more comfortable with it compared to previous versions.

Sonic Boom also carried the idea into its show, hinting at it from the start and focusing on it in the episode "I Can Sea Sonic's Fear From Here."
