Edward Kenway

Edward Kenway made a cameo appearance in Blackbeard vs Al Capone and was portrayed by Xin Wuku.

Information on the Cameo
Edward James Kenway (1693-1735) is the main protagonist in Assassin's Creed IV: Black Flag. He is a British privateer-turned pirate and a member of the Order of Assassin's. Edward joined the British Royal Navy early in his life and, once accepted, found himself stationed in the West Indies. However, a quick end to the war and the promise of gold, glory and fame eventually seduced him into a life of piracy; it was during this quest that Edward first encountered the Assassin Order, and became embroiled in their struggle.

Appearance in the Rap Battle
Edward Kenway is seen with Al Capone's Mobsters in Capone's warehouse at the start of Al's second verse. Then he's next seen sneaking on Blackbeard's background. During the line, "I'm the emcee Assassin, slash like Edward Kenway!", Edward starts killing Blackbeard's Pirates.
