The Edgehog is an enemy in Final Fantasy Mystic Quest.
The Edgehog has two phases: It starts with a full set of quills, but after taking damage the top portion of its body becomes shaved.
In the German version, it is called "Cinos". Spelled backwards, the name becomes Sonic, the mascot of Sega, who was Nintendo's rival at the time of the game's release. This pun was even reflected with the color of the creature's quills, which was blue just like Sonic's.
