Sico Rudo (Earth-616)
From J-Wiki

Sico Rudo was a saboteur working for the Imperial Japanese Army during World War II. Rudo was tasked with destroying American shipping supply lines and appeared as the ringleader in a plot to wreck vessels in the Pacific by bomb placement. In his only known comic appearance, Miss America uncovered Rudo's sabotage plans, pursued him, and ultimately foiled his scheme. Rudo’s subsequent fate is left unrevealed, as was common with many Golden Age one-shot villains.
