I take back everything I said... I just checked up their article on Wikipedia. Death rays? Claws? Flamethrowers? The PLUNGER can crush human skulls? And on top of that, they're actually living organisms within robot shells - thus technically cyborgs? Oh no, their threat rating just went up from a mediocre 2.4 and hit OVER NINE THOUSAAAAAAAAND!!!
Sorry, couldn't help myself.
