'Hunger' is a new comic miniseries tied in with the Age of Ultron storyline. The story is that with all the time and space tom*vulgarity*ery going on in the Marvel universe in recent years, it has created a hole in time and space that leads to the Ultimate universe. Galactus ends up falling through and meets his Ultimate counterpart (or counterparts). Silver Surfer is obviously tied in as well, though apparently Rick Jones will be the main hero alongside the Surfer.
Do you think all the Mainstream/Ultimate crossover series that are appearing are getting too lame and preventing what Ultimate Marvel was made for? To differentiate itself from the main universe? I mean, first we had Shattered Dimensions, then we had Spider-Men, now we have this. While Shattered Dimensions had next to no effect on either universes, Spider-Men I think did have quite a bit of an impact on Miles Morales and Peter Parker. This one will probably have severe concequences though. I mean, a giant purple guy with a goofy helmet and cosmic powers invading a relatively down to earth (for a Marvel world) earth?
