A Hulk series is expected to be the pair's new project following the release of an image with the word "indestructible" written in green.

The Marvel NOW! initiative will see a major shake-up in the publisher's creative teams coming out of Avengers Vs. X-Men.

Secret Invasion illustrator Yu has had an extended period of collaboration with Mark Millar on various titles published through Marvel's creator-owned Icon imprint.
The presumed Hulk project will launch in November.
