The blue hedgehog is the world's fastest thing alive. Sonic is known to never back down and likes to take a challenge. He likes to annoy his nemesis, Dr. Eggman by destroying his plans. He likes to pass time by running a lot. He likes to go wherever the wind takes him. Sonic is a fifteen-year-old teenage hedgehog who loves adventure, excitement, and is a fun-loving guy. His young energetic voice also matches his free-spirited and cocky personality. He can also get stubborn at times and can be very impatient on some occasions here and there, but he does show to have a very big heart and he cares very well for the safety and loyalty of his best friends.
