So maybe half the size of the buzzsaws and add missiles? I suppose I could, if I had to... But my philosophy is simple.

To destroy your enemies all you need is the power to do so and the means of efficiently delivering that force, even to the detriment of everything else. I trust human ingenuity for the rest.
I could go with a buster beam or something but that'd bore me. 'You're original or you're nothing' constitutes the second half to that philosophy.
