The 23rd Century, the future is a time of robots and aliens. The people of Earth have banded together along with several other peaceful alien races to promote peace throughout the galaxy, forming the United Planets. As part of the United Planets, the Galactic Patrol — a body of law-enforcers — works to maintain order, under the leadership of Commander Rondu. However, a powerful criminal organization called SHADOW is out to destroy both the Galactic Patrol and the U.P. Led by Lord Umbra, a massive cyborg-computer, SHADOW employs sinister agents and incredible schemes to attack and someday rule over all corners of the known-galaxy. There is one thing that helps to fight against SHADOW: ingenious inventor Rob Simmons — secretly a member of the Galactic Patrol — creates six special robots who can use their unique powers to battle against the forces of Umbra. Together, these robots can unite to form a giant robot called Mighty Orbots, to fight for truth, justice and peace for all.
