Note: They’re arguably the most memorable twins in super-hero comics, but they’re also one of the most strange. Originally created for DC’s late-70s animated show The All-New Super Friends Hour, artist Andy Trabbold gives the twins a more serious visage. - Chris A.
Here’s what Andy had to say about the designs:
I wanted them to feel more alien but still keep the feel of Zann and Jayna. The colors are close to their original outfits but darkened a tad. The suits are similar but not identical- after all, they’re twins, not clones. In regards to the chest symbols: I always dug the idea that Superman’s S symbol is actually the symbol for the House of El that happens to resemble a human letter. I did the same here- the twin’s chest symbols are alien markings that resemble earth language letters.
