What is Mindbubble? Well, fans will find out at New York Comic Con.
All we know right now is that it's by Rick Remender, Pascal Alixe and Nic Klein and that it's the latest one-word preview offered up by Marvel Comics as to their plans for next month's convention and the All-New Marvel Now.
As one might expect from the involvement of Remender, the reveal will come at October 11's Avengers panel. What do you think it might be?
