At the Super Buddies message board, there's a user under the handle "NightwingTAS" who builds digital figure models off the Bruce Timm DC Animated Series template for further fan fiction adventures of his own devising. The 10th and final entry in the "Z'Onn "Z'Orr" series, here's his take on Jemm, Son of Saturn...
Jemm cmae through the Infinite Crisis changed. He is now the king of Saturn and has united all three races as well as welcomed a new race the Lanthonians, who are now the Titanians. Through the strifes of the Infinite Crisis Jemm has done something that no Red Santurian was ever able to do until now, he broke the mental blockade that prevented him from shapechanging and is now able to do so. Jemm has decided to make himslef more known as well as his people so he followed in Princess Diana's steps and has assumed the role of an Ambassador on Earth and took the name Santurian. While Jemm is away on Earth his wife the Queen rules in his place, much like Aquaman.
I'm happy to see Jemm continue to be treated as part of the Martian Manhunter Family, which dates back in print to Morrison & Ostrander in the late '90s, and behind the scenes to when Jemm was going to be a Martian in his original 1984 mini-series (before concurrent plans to use Martians in a JLA story arc forced him to turn Saturnian.) I also like that, although NTAS' stated premise is that "My DCU veers off from the DCU on New Earth as of Infinite Crisis," he incorporates James Robinson & Pete Woods' revisions to the character in books of more recent vintage like New Krypton and Adventure Comics. I do have to point out though that Saturnians already possess a degree of shapeshifting (see: Cabal,) and that there's already a Martian Manhunter villain called "The Saturnian," at least by me, because the only alternative is the unwieldy "Saturnian Criminal." Well, I guess there isn't a
