Here I come, rougher than the rest of them
The best of them, tougher than leather
You can call me Knuckles, unlike Sonic I don't chuckle
I'd rather flex my muscles
I'm hard as nails, it ain't hard to tell
I break 'em down whether they solid or frail
Unlike the rest I'm independent since my first breath, first test
Feel the right then the worst's left
