Sonic the Hedgehog

Sonic is the title character and main protagonist of the Sonic the Hedgehog series and Sega's mascot. He is a fifteen-year-old, blue, anthropomorphic hedgehog gifted with the ability to run at the speed of sound and beyond, hence his name, and he possesses lightning fast reflexes to match. As his position as a hedgehog implies, Sonic can also roll up into a ball, primarily to attack enemies.

Ever since stepping into the battle against injustice, Sonic has been the champion of peace and is known as the world's renowned hero for saving it many times. Well-known for his legendary cocky attitude, easy-going demeanor and somewhat short temper, yet strong sense of justice, compassion, heart of gold and love for freedom and adventure, Sonic uses his abilities to protect the innocent of his world and those beyond from the forces of evil, especially his arch-nemesis Dr. Eggman who constantly seeks world domination.

Sonic has been acknowledged as the most recognizable and famous character in the Sonic the Hedgehog franchise according to an official popularity poll in 2011.

In Shadow and the Snow Queen
