Agreed. He was the only one to never truly declare himself the villain at first. Ghetsis was smart and literally raised and manipulated someone who he could control. I think his plan for taking over the world was by far the most likely to succeed. The only flaw was that Ghetsis didn't plan on the main character (Hilda/Hilbert).
