Sonic has been described as being "like the wind"; he is always on the move, always moves forward and is noted for being free-spirited and adventurous. He values freedom above all else and lives his life according to his own rules and simply enjoys traveling the world (and beyond) while searching for adventure.
Sonic is mostly laid-back, cool and enjoys relaxation and firmly stands for freedom, but he is never one to rest in the face of injustice or oppression. He hates evil in all its forms and can easily be riled up about it; if he witnesses someone being opressed, are suffering from injustice or are simply depressed or despairs due to others' actions he will not show a moment of hesitation and will instantly step in to help those in need, even if it means that his actions will be met with contempt, as stated in Sonic and the Black Knight.
