Behold the mighty T522 Enryu, a Japanese rescue robot:

Co-developed for the last three years, the 3.45-meter(11-foot)-tall, about five-ton robot can be operated manually by a man aboard it as well as remote control and lift heavy objects that weigh up to about one ton with its two arms that move like ones of a human. The developers plan to improve the robot to be used in rescue operations at the actual disaster sites by the end of this year.

It can also be used to fight off alien invaders.

(Thanks to El Rey for this one!)
