The “alien speak” in the DC New 52 comics, specifically ones tied into the Justice League Darkseid-searching-the-multiverse-for-his-daughter subplot, is created using Comic Craft Gobbledygook’s font.
And Justice League of America’s Vibe #2 was no exception. The first few uses were funny in that they translated to “alien language”, and “alien scream”. But the translation of the scroll meant for the incarcerated Gypsy was intriguing. If you take a mirror-image of it, it translates as:
Whose girlfriend is called Maite?
It also almost looked like the beginning of a proposal, but the subsequent alien text just repeated the above.
Maybe in issue 3?
