Sonic is confident, fast-talking, sarcastic, a bit obsessive, and easily annoyed, especially by Knuckles. He jokes through danger but panics when caught off-guard, and despite his attitude he steps up as the reluctant hero. Voice should be youthful, energetic but not hyper, with a natural American accent. Requires comedic timing, snarky delivery, and the ability to shift quickly between humor, panic, and action.
