Sonic the Hedgehog

Introduction
Sonic the Hedgehog is the title character and main protagonist of the Sonic the Hedgehog series and Sega's mascot. He is an anthropomorphic American hedgehog gifted with the ability to run at the speed of sound and beyond, hence his name, and possesses lightning fast reflexes to match. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies.

Ever since stepping into the battle against injustice, Sonic has been the champion of peace and is renowned the world over for saving it countless times. During his many adventures, Sonic has traveled from the ends of the world to the far reaches of space and time, while facing countless trials that have tested him to the fullest, earning him many titles, allies and the scorns of several foes. 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 from 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, undoubtedly, the most recognizable and famous character in the Sonic the Hedgehog franchise according to an official popularity poll in 2011.
