10. Tech N9ne
Tech N9ne could forgo mainstream hip-hop acceptance, and he has, and still be a successful rapper. The Kansas City, MO emcee is a rhyming oddball, his flow is masterful at a level that an experienced emcee can't fathom. He also dresses as strange as his raps can be.
N9ne is known for painting his face, spiking his hair in hellish, red picks, and sporting a sprawling scruff off his chin. He's hardly the average rapper you grew up on, but he's not a good dresser by any means.
He killed it at the 2011 BET Cypher, showing up Big Krit, Kendrick Lamar, Machine Gun Kelly, and B.o.B. with a sporadic, yet calculated cadence. And if he found a new wardrobe, his dominance over the rap game could be real scary.
