(Master Comics 013, 1941)
The long and the short of it is that the Choker is an old-fashioned escaped homicidal maniac of the sort who indiscriminately kills everyone who crosses his path - more akin to a rampaging monster than a villain, plot-wise. He gets into a couple of scrapes with Zoro the Mystery Man (who, by the way, proves susceptible to the worst little old lady disguise in comics history) before meeting a rare Death by Cheetah.
Also: a seldom-seen shoeless villain!
