Knuckles is independent, wild, tough, and a loner by nature. Like how Sonic embodies the wind, Knuckles embodies the mountain, stern, unmovable, and anchored to his duty. Due to having lived in seclusion for most of his life, Knuckles is a rather antisocial and reclusive individual. As such, he cares very little about what others think, which makes him bluntly honest, straight-forward, and somewhat egotistical.
