Sigma did not go nuts thanks to the Virus, that's a fan assumption.
かつてはイレギュラーハンター第１７部隊の隊長であったシグマ。その圧倒的な戦闘能力は史上最強といわれ、特A級ハンターとして仲間に尊敬され、信頼されていたレプリロイドである。だが、ある日、正体不明の赤いイレギュラー（ゼロ）との戦いにおいて敗北を喫し、最強と自負するプライドがズタズタにされた。このときにゼロからイレギュラー化を促進するウイルスに感染し、邪悪な心が芽生えてしまう。数ヶ月後、完全に邪悪なウイルスの虜となったシグマは、その圧倒的な力と天才的な頭脳で大勢のレプリロイドを従え、人間に対して反乱を起こしたのであった。
Sigma was at one time the Commander of the Irregular Hunter 17th Unit. A Special A Class Hunter, he was called the strongest in history due to his overpowering combat abilities, and gained the confidence and respect of his fellow repliroids. However, on a certain day, he suffered a defeat in battle by an unidentified unknown red irregular (Zero) that tore at his proud ego. At that time he was infected by some manner of virus that facilitates irregularity, germinating wickedness in his heart. Several month later, Sigma was completely enslaved by the evil virus, and used his overwhelming strength and genius intellect to subdue many repliroids into joining him in a revolt against humanity.
しかし、ある日ゼロに敗北し、イレギュラー化するウイルスをうつされてしまった。邪悪な心に支配されたシグマは、人類の敵としてエックスたちの前に何度も現われることになる。
But, one day, [Sigma] suffered a defeat by Zero, and was inflicted with an irregular converting virus. Under the control of an evil heart, Sigma made enemies of humanity and popped up to cause trouble for X and his companions many times over.
そんな彼が、なぜイレギュラーと化してしまったのだろう？あくまで推測ではあるが、イレギュラーだったZEROと戦ったとき、イレギュラー化を促進するウイルスのようなものを浴びてしまったのが原因ではないだろうか。
Just why did he become irregular? There has been much conjecture, but the actual cause could well be from when was showered in some kind of irregular-facilitating virus during his fight with the irregularly behaved Zero.
ゼロのイレギュラーのウイルスにおかされて、シグマは、じゃあくになってしまう。
Invaded by Zero's irregular virus, Sigma became evil.
Every X4 related sourcebook makes a relation between Sigma going evil and the virus infection, some more blatant than others. And then there's...
4) What was the inspiration for Sigma?
KI: Some people think he might have been inspired by Sagat from Street Fighter because of his look, but that's not actually the case. Sigma and Zero basically represent the idea that nothing is absolute. Sigma was a powerful leader of the Maverick Hunters but after Zero passed the virus to him, his allegiance changed. Circumstances can change anything, and nothing is absolute.
Inafune sounds confused. Maybe you guys need to explain how Sigma was going to change his allegiance anyway even if he never had the virus. Or more accurately, that Sigma's allegiances never really changed at all, because he was an unemphatic calculating monster from the beginning. It's so obvious! /sarcasm
As a man without worrying, compassion, hesistation, as a man of logic, that is the conclusion he came up with.
Being decisive doesn't lend itself to being amoral or without compassion. When Cain talks about Sigma not having X's problem of worrying too much, he is not saying that he thinks Sigma is entirely unfeeling or morally bankrupt. His rebellion was as much a surprise to Cain as anyone else.
Sigma's philosophy was first formed by seeing X's justice, before he ever came into came into contact with Zero he already began to think about the imperfections of the world. That philosophy is what binds the new generation.
It's a wonder how or when Sigma ever saw X's justice, especially to say it was early on, seeing as X didn't join the Hunters until after Zero did, which would also be after the virus was already inside Sigma. In fact, unless Cain's speech about X in the Day of Sigma video was a repeated speech from a rambling old man, it doesn't seem like Sigma had much interest in X, his weak justice and worrying et al, before the events of that time just before his rebellion. Which was already in the works before the conversation about X took place, seeing as Sigma's henchmen were behind the mechaniloid hacking at the start of the movie, and according to the chatter at Hunter base was but one in a subsequent series of such events.
It is possible that they did have some unknown conversation or shared experience which divulged X's sense of justice way back at the dawning of the reploid era, and it had such an impact so as to influence his entire train of thought for all points hereafter, then Sigma even after convincing himself that there was no justice in his own actions, he still accepted the job of Hunter commander and performed it for over 2 years without faltering, without complaining or confiding in anyone that we could tell of, and still spouting the same political rhetoric he so loathes as if he believed it. A very long time to bear such a cross, but maybe Redips did it for longer, who knows. It could be.
It's just that the only true support for it is Sigma's dialogue in X8 where he's clearly taunting X, this time his ideals. A statement which could also be explained by Sigma judging X's "justice" after the virus infected him and X joined his group, in scenes such as we see in IHX. After taking effect from the virus. Fueled with evil that needed an outlet, having lost the perspective to which he previously kept, Sigma found something to rebel against. What it is exactly probably doesn't matter to the virus much at all. If Sigma believes the human society, or X's ideals, are what is wrong with the world, it's fine so long as he's convinced enough of its intolerableness. It doesn't even need to be fully justifiable, just strongly believed.
"It is not the case that Sigma was by any means insane."
Says the clearly excellent judge of sanity. Lumine believes Sigma's choices to be his own in the same way he views his own choices his own, despite his and all the New Gen's awakenings being the result of Sigma's tampering with their Copy Chips. Lumine believes he made a choice to follow Sigma. But he also holds that it is the only correct choice, and all awakened NGs seem to agree. Out of those countless analyzed old generation reploids, out of all their possible ideals and morals, only Sigma's came to a head? That incredible statistic shows that it was in fact a very weighted game, if it weren't clear enough when Sigma took credit for their specific addition made during manufacture. They were not designed to make any other choice. When it comes down to it, Sigma's DNA is as equally vehement as the Sigma Virus that is his true form, and in fact are probably one and the same, just on a much more thorough scale.
In X5 Sigma Died for real. He did not have enough Virus, and could not trigger his revival program. He for all intents and purposes, died for good. If it weren't for Gate, He probably would have stayed that way.
All of which Sigma completely denied, of course. Did he need the help? Had he really died completely? Sourcebooks say yes, Sigma says no. That Sigma was unable to admit his own failing tells us something about him.
also, Horobe! Its called in fight dialogue. Just like X yelling STOP IT! when he fires his buster in X7. or Zeros comments in CM.
That "Horobe!! Horobe, horobe, horobe!" thing CyberXIII was talking about wasn't move-use related, it was cutscene dialogue. The one that only appears on hard mode, when Sigma snatches your character with Mirage Claw and a brief scene plays out where your partner saves you.
Be whatever title they were given, they were humanity's slaves in the X series more than companions.
By setting accounts, the vast majority of reploids and humans lived together in peace. Reploids were integrated into all walks of society. Not just lowly employees or laborers, they were also the site managers, the the factory bosses, the politicians... Reploids even police themselves. The Hunters don't simply exist to protect the humans' rights, but to protect reploid rights as well. An irregular isn't just a threat to humans, it's a threat to everything and anything around it, other reploids included. The Hunters are "both sword and shield to those who cannot protect themselves." For humans and reploids. Employment was up, demand was high. If anything, human laziness accelerated the production of reploids. Why Sigma thinks that humanity is holding them back could be more a question of their "strong and weak are equal" conventions that society is based upon. It is true that their society was not perfect, and injustice did exist. But Sigma's answer to those kinds of injustices is to heap even more injustice on top of it, for both humans and for reploids who don't submit to his rule (and even those that do wind up meeting untimely ends at his orders). Sigma's only consistent ideal is that the strong (being himself) should rule and the rest are the weak, to be used as the strong so pleases.
Being a murderer or being a mass murderer does not make you insane.
It doesn't help, though. As was said many times already, sane vs insane is a judgment based on a sense of "normalcy" which changes from viewpoint to viewpoint, a call made by the opinions of contemporary experts or of a jury of one's peers... Sigma's obsession with power, belief in his own superiority, lack of sympathy for others or remorse for any harm caused by him to anyone, going to any length of manipulation, mayhem and murder to achieve his selfish and often perplexing goals. Some experts could well find someone with his collection of neuroses to be quite insane. Lumine thinks it visionary. Maybe it's all true in some ways.
X8 clearly proves that using the DNA of the original Sigma induces the same state of mind as the current Sigma
Where did it prove that? Sigma says he had his own data engraved on the copy chips, but nothing in X8 says that the Sigma data in the copy chip is Sigma's data without any of that viral influence at all. The opposite, the ultimate destroyer's DNA contribution is highly credited. It's mentioned many times that Zero had the potential to be like Sigma and join with the New Gens as well. Why? The virus. Or rather, Zero's original programming. The removal of inhibitions, the desire for the purity of destruction. To become a new world's messiah, Omega might say. But our Zero rejects that path, and so must be destroyed as well.
Sociopath-Antisocial Personality Disorder
Looking it up on
Wikipedia, I think there is a very strong case to say Sigma would fall under this disorder's guidelines. Seeing as you only need to meet 3 or more of the diagnostic criteria, and of the 7 they list, only 2 don't sound too much like Sigma. But there is some question in applying that kind of human mental disorder to a reploid. For instance, narcissism among reploids may be easier to justify than among humans, by data analysis reploids could theoretically compare certain exacting specs or rare abilities. Recklessness self-endangerment for humans can result in very final consequences, while reploids who can be repaired from much worse damage than humans may endure, or even swap bodies and be resurrected as Sigma so often does, the consequences of that behavior becomes less severe. Even where circumstances may not apply, I personally think of Sigma as a psychopathic megalomaniac. And will defend that position, if anyone wants to argue.
What source denotes Neo Sigma as Sigma's FINAL form in X2 and not his first?
I have a lot of books discussing X2, some game guide books and some source book types. Sigma's X2 first form is just called Sigma in every one of them. The only book I have that uses the Neo Sigma for anything at all is the Compendium of X, and it only uses it on the second form of Sigma. I think the credits were simply mistaken in which name they used associated with those meaningless rp numbers. Sometimes the credits make mistakes.
