Kamacuras is not one of the tougher Kaiju out there, but he is still a formidable beast. He has a lot of power and can fly at a quick speed. Still, that won’t be enough to stop Lelouch. While Lelouch’s eyes won’t be a factor here, he still does have a fairly quick robot suit which he can use to fly rings around this insect. Kamacuras will get blasted by his many armaments and eventually they will take him down for the count. Kamacuras won’t be able to counter attack. Lelouch wins.
