Shingo

Shingo was a person who wrote a very harsh letter denouncing the Marvel Generation 1 comic that was published in an early issue. The editors followed this letter with their own rebuttal, and challenged Shingo to write back. Although Shingo apparently never wrote to Marvel again, he became a running joke among the comic's readers and editors. Fans would occasionally sign letters with names such as "Shingo XVII", or end letters with statements like "By the way, I spoke with Shingo a while back and he says Transformers are cool." Eventually, the editors went so far as to hold a contest called Spot the Shingo, in which the object was to find Shingo's name hidden in the artwork of various panels.
