When King Mortus, the Evilest of all Evil Immortal Kings, sends Marvin, the Not Worthy to conquer Earth things do not go as planned.

King Mortus grunted and groaned in an effort to think harder. He was close to giving up when an idea shattered his crown and scorched his never combed royal hair. Now he knew exactly what to do.

He would conquer Earth and make miserable slaves of its people. Yes, that is what he would do.
