Sonic the Hedgehog

Sonic the Hedgehog is a blue hedgehog with the ability to run faster than the speed of sound, and the titular protagonist of the  series.

Sonic's journey began when he sought out to rescue the animals of South Island from Dr. Ivo Robotnik's scheme to use them to find the Chaos Emeralds. Since then, sporting a strong sense of justice and a confident attitude, he journeys to preserve peace and protect the innocent, and regularly faces off against adversaries like the evil Dr. Robotnik, now going by "Dr. Eggman". He has fast reflexes and fights by curling into a ball and attacking enemies.
