And three new versions of Kanigher and Andru's creation were attempted in the last couple of decades: John Byrne reworked him into a Apokoliptian supercomputer in his run on Wonder Woman, and there was Chang Tzu of the Oolong Island Science Squad from 52, and later mainland China's Great Ten government-sanctioned "hero" team.

And then, there's Edgar Fullerton Yeung from the post-Flashpoint version of Harley Quinn...? But that one's after my time as a DC reader...so I guess the attempts-to-salvage something perceived as truly useful will continue. Otherwise the trademark reverts to the Kanigher and Andru estates, I suppose.
