New concept art has been released from Guillermo Del Toro's Pacific Rim.  The story is kicked off by the rise of monsters (known as Kaiju) from the sea who start a war that devastates humanity.  To fight back, the humans build giant robots (known as Jaegers) that are controlled by two pilots.  One of the pieces of concept art gives another look at the jaeger "Cherno Alpha".  As for the other, I assume it's a kaiju skull, although with the designs on Del Toro's films, it's sometime difficult to know what body part you're looking at.

Hit the jump to check out the concept art.    The film stars Charlie Hunnam, Idris Elba, Rinko Kikuchi, Charlie Day, and Ron Perlman.  Pacific Rim opens in 3D on July 12th.

Here’s the official synopsis for Pacific Rim:

When legions of monstrous creatures, known as Kaiju, started rising from the sea, a war began that would take millions of lives and consume humanity’s resources for years on end.  To combat the giant Kaiju, a special type of weapon was devised: massive robots, called Jaegers, which are controlled simultaneously by two pilots whose minds are locked in a neural bridge.  But even the Jaegers are proving nearly defenseless in the face of the relentless Kaiju.  On the verge of defeat, the forces defending mankind have no choice but to turn to two unlikely heroes—a washed up former pilot (Charlie Hunnam) and an untested trainee (Rinko Kikuchi)—who are teamed to drive a legendary but seemingly obsolete Jaeger from the past.  Together, they stand as mankind’s last hope against the mounting apocalypse.
