Sigma put importance on VAVA not just because of his combat capabilities, but also his mental state. By having nearly everyone have defects in their electronic brains, ruins what makes VAVA special.
I disagree. I personally- Think Vava is pretty special no matter what. Not only is he an irregular of his own accord, but you could say he always was one. He was made with the defect, he always enjoyed destruction, It got him into trouble as a Hunter. I think its more not just the defect that makes him special, but just everything that makes him who he is. from his look to his personality, to his abilities, and his history.
If we had well, lets take Larry as an example again, if he were compared to Vava, he still wouldnt really compare. he would just be like any other reploid gone nuts. He would be terminated, end of story.
Yet our purple/blue/green faceless friend here, is not just "a reploid gone nuts". The defect is said to cause his destructive persona. Thats just the thing though. He was always that way, from the very start. And his defect is unique in making him who he is. He is a war machine, from head to toe. He is an A class Ex hunter. he has a grudge against X, and constantly sides with Sigma, because Sigma allows him to run rampant as long as he serves him. even with introduction of other reploids with defects, it really wouldnt damage Vava's uniqueness at all. Thats like saying Colonel isnt unique because Signas happens to resemble him. they have similar features, but both are unique. In the same way, even if both Vava and Larry here are irregulars caused by defect, doesnt make Vava any less special. in fact, it makes him MORE special. Because out of a small group of reploids that are made with defects and either do or do not go nuts because of them, He stands out, he is unique, he is superior, he is Vava, the over destructive A class hunter who has revived over and over, and will haunt X to the day he dies.
Also, defect? He has been revived over and over, and he is always the same, and while the initial Vava had the defect in his brain, im not so certain that his subsequent bodies would have such a flaw in their design. yet he remains the same.
For the sake of argument, lets say that he was eventually repaired of his defect. He was still destructive for God knows how long. That is his personality. Its who he is. Are you so sure The defect si what KEEPS him that way? Its what casued it, but thats what he has become and always will be, he cannot change, and doesnt care to. He has developed a destructive personality. Its not just caused, but learned behavior as well. Its become part of him.
Which is another reason why he is so unique.
