Godzilla: Mechanical Titan of Terror!

From IGN:

The first poster for Toho Animation's Godzilla anime sequel has been released, and it features Mecha Godzilla.

The image was revealed on Twitter and it features the sequel's main cast of human characters, Godzilla, and of course the new Mecha Godzilla hinted at in the last film. The poster also teases a battle between the two Godzillas.

The sequel is titled Godzilla: City on the Edge of Battle and will hit Japanese theaters on May 18, but doesn't have a U.S. release date yet. Kobun Shizuno and Hiroyuki Seshita are directing the sequel, from a screenplay and story concept by Gen Urobuchi.
