Ha! Chandu... I have to Google him. I know Doc Savage and Tom Strong...
The Shadow is basically Chandu except with guns, hiding half his face with a scarf, and specializing in just one mental trick learned in the mysterious far east
So, backwards: take away The Shadow's guns, don't hide his face, and let him be a bit more of a jack-of-all-trades as far as mental tricks learned in the mysterious far east, and you've kind of got Chandu.

I'll make you know what I came up with.
Please do.
