So before they could be embarrassed any further, Marvel called off the whole thing, comic book and all.

And released a statement:

The activation with Northrop Grumman at New York Comic Con was meant to focus on aerospace technology and exploration in a positive way, However, as the spirit of that intent has not come across, we will not be proceeding with this partnership including this weekend's event programming, Marvel and Northrop Grumman continue to be committed to elevating, and introducing, STEM to a broad audience.

Seems fans know that "Hey kids, learn STEM so you can design weapons of mass destruction for the Military Corporate Welfare State!" isn't the message Marvel should be promoting.
