Mark Swift

Golden Age Origin
Mark Swift was an orphan in the town of Greenville, who was adopted by his grade school teacher, Rodeny Kent. Kent was actually a genius who built a "time retarder" which he called "The History Express!" Kent decided that instead of simply teaching Mark history, he would show him history, taking him on trips into the distant past. Mark and Rodney were not simply content to observe history however. They felt compelled to solve mysteries, battle injustice and help those in need. Over the course of their adventures, they encountered many famous historical figures, including Napolean, King Richard, The Lionheart, Alexander the Great and Blackbeard. Mark was an Eagle Scout and demonstrated great resourcefulness on his adventures.
