Information on the cameo
Genghis Khan's descendants are Khan's multiple progeny who live in New York and Japan. They live in these areas due to the large Asian community residing there, making it likely that several people from these places have Genghis Khan's genes. These men are the result of Khan's tendency to rape women in the Mongol conquests he led during his reign, and this caused approximately 0.5% of men in the world's current population to be able to trace their lineage back to Genghis Khan.
Appearance in the rap battle
Genghis Khan's descendants appeared when Genghis Khan said the line, "Now my DNA's in dudes from New York to Japan!"
