Katana Robo: RTA

Katana Robo fights his way to the top floor of the Robot Tower, which looks like a platformer game stage, to thwart Samurai Robo's ambitious plan to use the Dominion Sphere at the top of the Robot Tower to control the robots throughout the universe.

To thwart Samurai Robo's plan to take control of all the robots in the universe by awakening the Dominion Sphere from the highest point on the planet Mechanos, Katana Robo rushes to the Robot Tower, which looks like a platformer game stage made up of buildings, cars, space battleships, and more. Raising his Dominion Sphere as high as he can, Samurai Robo harnesses the power of the Dominion Sphere to bring objects together to create an impromptu robot tower, which is defended by numerous enemy robots that serve Samurai Robo. Katana Robo's journey includes battles with a variety of enemy robots, and it's up to you to destroy the Dominion Sphere before Samurai Robo can fully awaken it and turn the robots of the universe into his minions.
