With expert timing, we jump out of the shadows for another Introducing...! This time, we focus on the first appearances of some of the most nimble martial artists of the comic book world: DC's Karate Kid, Marvel's Shang-Chi (now a major motion picture), and Mirage's (now IDW's) Teenage Mutant Ninja Turtles. If you'd like to read along with us, you can find these character premieres in Adventure Comics #346, Special Marvel Edition #15, and of course, Teenage Mutant Ninja Turtles #1. These origins also manage to span the Silver, Bronze and Copper Age of comics, as America's appreciation of the martial arts went from a passing glance to a full blown obsession. How do the issues hold up? Listen in to find out, but please, don't try this at home; leave that to the Living Weapons. (1:15:35)
