Get set for a live-action version of Transformers, as the company behind giant Japanese robot Kuratas has accepted a duel challenge from upstart US challenger MegaBot. However, it'll only fight on one condition: Combat must be hand-to-hand with no guns. Kuratas has been around for three years and even went on sale for $1.35 million at one point. Since MegaBot was only just completed, the Japanese company was taken aback by the offer to fight. Still, it couldn't resist needling its new rival. "My reaction? Come on guys, make it cooler. Just building something huge and sticking guns on it is... super American," said CEO Kogoro Kurata.
