Marco Polo
Marco Polo was a Venetian trader and explorer who was one of the first Westerners to travel the Silk Road to China.
When Jimmy Olsen photographs the Star of Cathay at the Metropolis Museum, he passes out and awakens in the middle of a battle where his compatriots hail him as Marco Polo. Assuming the identity of Marco, Jimmy engages in several battles with the minions of Lord Timur, a rival of Kublai Khan, over the possession of the Star (SPJO No. 157/1, Mar 1973: "The Strange Second Life of Jimmy Olsen!").
