The Cole Twins
Out of the way, Usos. Buh-bye, Bellas. Decades before those twins were on top of the wrestling world, WCW debuted Keith and Kent Cole in 1993.
The mullet-wearing identical twins never got past the preliminary match level, jobbing out to the likes of The Hollywood Blonds and Harlem Heat before quickly disappearing. Fun-fact: A young Triple H's debut match in WCW (under the clever name as Terra Ryzin) was against Keith Cole.
