Trivia / Hellfire Gala

• Meaningful Release Date: Planet-Size X-Men just happens to be released on June 16 or 6/16, like Earth-616, the main universe in the Marvel universe.^note Please note: this only works the way Americans write dates. In almost every other country, it would be written as 16/6. The creators admitted that it was more of a lucky coincidence than anything else, but one they were perfectly happy to take advantage of.
