Knuckles is independent, wild, hot-blooded, 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.
