The empire of Lord P?kello was ever growing. One by one star systems have fallen before his vast armada and trillions have been bent to his iron rule. And now he has set his eyes upon a tiny blue and green world. Its inhabitants technology was primitive to say the least. Their cultures divided by petty ideals and beliefs. Subjugating them wouldn?t even be an effort.
P?kello never expected them to counter attack with a giant super robot left behind by a long lost and highly advanced civilization.
I thought the bad guy from Voltron was called Zarkon LOL I'm just kidding of course but there is a similarity although I think Zarkon used giant monsters.
