If you like the character you might be interested in Alan Moore's 'Terra Obscura' version of the NEDOR characters. [Nobody owns the copyright, so anybody can use them. Even you] He changed the name to Doc Strong (emphasizing the Doc Savage connection- and since he introduced the character in a Tom Strong book) and put all the characters on a counter-earth. 2 mini-series. Currently Dynamite is publishing 'Project Superpowers' it's their third series using these characters. There have been other versions.
Cheers.
