Sonic the Hedgehog

ソニック・ザ・ヘッジホッグ

Sonic the Hedgehog, nicknamed the "Blue Blur," is famous for his speed, which is described as "second to none." He debuted in the game "Sonic the Hedgehog" for the Sega Genesis in 1991. While he likes to relax and have fun, most games center on the main villain, Dr. Robotnik, trying to conquer the world, only to be thwarted by Sonic and, at times, a few of his friends.
His closest friend is Miles Prower, better known as Tails. Serving initially as a sidekick and gradually evolving into a partner over the course of the series, the young fox has a talent for inventing gadgets and machinery.
He frequently teams up with Knuckles the Echidna, the guardian of the Master Emerald. Knuckles has been labeled his rival on multiple occasions, and the two generally get along well.
Sonic is proud and dislikes being restricted, valuing freedom and acting on his own terms (which invariably means moving at incredible speeds). Although he is arrogant and impatient, he would never abandon a friend in need or fail to protect the greater good, having taken actions that nearly cost him his life on several occasions.
Sonic primarily fights by curling into a ball and spinning at high velocity (moves known as the Spinball, Spin Dash, etc.). He is also skilled in Capoeira, a Brazilian martial art.
