Sonic is a habitual daredevil who is honest, loyal to friends, keeps his promises, and dislikes tears. He took the young Tails under his wing like a little brother, but appears to be uninterested in the marital proposals from Amy Rose, but he thinks of her as a close friend. In times of crisis, he focuses intensely on the challenge as if his personality had undergone an astonishing change.
Sonic's greatest strength is his running speed, which is faster than the speed of sound. He appears as a blue blur when he runs. He can use the Spin Attack like in the games and appears in 3D, in this state he can break through virtually anything and a ring can increase his power similar to SatAM.
When seven Chaos Emeralds are collected he is able to transform into Super Sonic, a faster, stronger and better version of himself that can fly, teleport and move faster than the speed of light. He can also heal people with a touch. He has used super transformation against Perfect Chaos, Biolizard, Eggman, Dark Oak, and Super Shadow and other enemies.
