Byeonsinjadongcha Tobot 2nd Season

While cleaning the house, Hana and Duri discover a new Tobot Key that is still experimental. Duri activates it recklessly, causing Tobot Y to run out of control before the family learns the device's true purpose: it can combine Tobot X and Y into the much stronger Titan.

At Burung Motors, Diluk receives a dangerous offer from a new enemy named Acnee, who wants Tobot Zero's artificial intelligence. When the damaged data proves unusable, Acnee gives him an ultimatum and demands Tobot X and Y instead.

With a new fusion ability in their hands and a calculating enemy targeting their robots, the brothers must learn to command Titan while protecting the technology their opponents are determined to steal.
