The members were Long Shadow (based upon Apache Chief), Wind Dragon (Samurai), Juice (Black Vulcan), Downpour, and Shifter (Zan and Jayna, the Wonder Twins). Their base of operations is a nod to the Super Friends' Hall of Justice. The Ultimen also parallel the International Ultramarine Corps of the Howard Porter/Grant Morrison JLA run: both teams begin as rival heroes to the Justice League, but discover that they are the results of a secret government project under General Wade Eiling and will die in just a few years' time due to their experimental origins.

Note: This new Secret Society is similar in scale to the Legion of Doom (a supervillain group from the Challenge of the Super Friends animated series), and its base is an updated version of the one used by the Legion of Doom.
