In 1937, in an adventure in Europe he encountered Dr. Doom's parents and later Captain America villains Baron von Strucker and Baron Zemo and spent some time in Latveria and in Wakanda in Africa while foiling Nazi weapons intrigues involving the as-yet unnamed mineral Vibranium. Not long afterwards, having been evicted from his office, he began living aboard the "Mississippi Queen" at Sabbath's invitation. In that same year, he uncovered a Nazi propaganda plot in the comic book industry. He also broke up a cult of zombies, thwarted Baron Strucker's attempted assassination of a U.S. senator, exposed the phony "child star" Tina Timmons, and rescued the British ambassador from a terrorist.
