Analysis of information sources in references of the Wikipedia article "Legion of Doom" in English language version.
One of the nicest bits in "Alive!" was consciously making Luthor's team the villains that the audience had seen most of, more or less, and cared about. Which was good, since we were hopefully making the audience worry about and root for Luthor's group. This also let us come as close as we could to the classic 13 LOD villains. Grodd was now the enemy and was dead; Captain Cold wasn't around; Devil Ray and Grundy were gone and we couldn't use Scarecrow or Riddler, so we were left with: Luthor (who kind of counted as Brainiac), Bizarro, Giganta, Cheetah, Sinestro and Toyman. And no, I couldn't keep all 13 straight two years later without referring to my script and Wikipedia.
