The whole "I'm Shogun!" bit was from when I was first starting to design him. At first he had no brother and every time I drew him he'd say "I'm Shogun!" an homage to the character Sho'nuff from the movie The Last Dragon who'd always walk in and say "Am I the meanest? Am I the prettiest? Am I the baddest mofo lowdown around this town?" (all while his lackies are saying sho'nuff!) then he'd say "the shogun... of Harlem."
