He would crush the first humans that he saw as the alien DNA that was pumping through his arteries filled him with physical power, rage, and the urge to dominate. Walt would then take control of the planet through mind control waves which are generated in machines buried beneath the monorail footers. The rest, as they say, would be history. One interesting tidbit - in what the deranged/alien Walt would regard as a magnanimous move, he would force the few thousand humans that survive his purging as few slices of chocolate cake for breakfast each morning before they started their days in the alien grist mill. For reasons that would never be understood, a dim awareness of the Bill Cosby chocolate cake sketch infiltrated his cyber sleep.
