But the very first vajra they kill in the show was stabbed with the valk knife, so that argument doesn't work.

well, how many times did you see a Vajra getting stab with a knife ? If it only happens once, the Vajra network wouldn't find it necessary to develop a countermeasure. The warhead was used intensively in the previous wars, hence in time they develop immunity. (Even Brera mention "in the future" even his beam will be useless).

If your whole squad for some reason decided on a close combat with a knife, then maybe after few battle they can't be stabbed =_=

I never understood the logic of this. So, if you place a bomb under my bed and I survive the explosion, your next attempt to kill me would assume that I might be vulnerable to a bullet? And Plan C would involve a punch in the face? Er, shouldn't it be the other way round?

I only saw that episode once, but I really didn't get why you can stab a vajra but not shoot them or blow them up.

because you can only kill it with something you haven't tried before. Vajra evolved to be resistent to existing weapon, so you have to always try something new (regardless of which comes first bomb before bullet XD ).

Anyway, it just goes to show you give everything you got till you die, and not cry halfway just because the warhead is not effective anymore

(at least Brera still have his positronic beam)

- if warhead doesn't work, we use missile. If missile doesn't work, guns. If guns doesn't work then we just have to fight with fist, teeth and nails. As long as we're alive, we will keep on fighting ! - Ozma :inset song "try again": --> luvs this part
