America officially challenges Japan to a giant robot duel

It's time for a major battle.

The Megabots team, a group of American makers, have officially challenged their Japanese counterpart to the ultimate robot duel.

The video they released on their YouTube channel is a clear declaration of war.

The American duo shows off their "big guy," a 12,000-pound, 15-foot tall robot that can shoot massive paintball ammo. The whole video is subtitled in Japanese, to make sure that their rival will get the message.

The challenge is directed specifically to Suidobashi Heavy Industries, a Japanese company that produces Kuratas, a huge, rideable robot.
