∑; The Maverick War Instigator.

This is to review what Sigma has went through near the current latest installment in the X series.

At the end of X7, Sigma was shown to have been ejected from a Building, several stories up... Not to be shown again... Then we see in X8 a Sigma entity without anything of that body? No head, or body similarities.

This is where my theory comes from. Sigma manipulated Red Alert in X7, with most fighting the Hunters. Yet we can assume that few survived. But mostly we can assume that Sigma survived (obviously, but not the point) and from then disappeared.

My theory consists of Sigma going into hiding after the X7 events, and either using remaining Red Alert members as a cult to his aid, or other members whom perhaps have been following him for years. What I mean is, looking at the inconsistency of information after X7 to the full blown 'information' present within X8, something may not be flowing straight up.

After he was ejected from the building, his injured body would have sustained impact damage. But his core, his Head was still in okay condition. Which without the heads destruction, the Virus cannot be destroyed in that degree. So, Sigma survived, but with his followers, manipulated or whatever, taking his damaged body and/or head into hiding. To which where Sigma was projected into a machine that would keep the head alive. From this, we can also suspect that his dreams would still be of priority, but without a new body presently, he was unable to act.

So instead of Sigma taking over yet another body, what if Sigma's Virus was granted a Proxy sort to say, and a copy was created with the same potential with the Virus? And that Proxy was the Belial Sigma found in X8?

It would make sense for Sigma to ruse the Hunters into believing that he is gone. It gives Sigma another puppet to act on his behalf. And it furthers his grip on what is going on around him. Plus it is an overlooked possibility, other than another character granting Sigma a full DNA resurrection...

Many reasons I say this is because of the character inconsistencies between Sigma in X1-7 and X8. Plus the copy Sigma's in completely different forms. Perhaps it is that body Sigma resides in within X8, but it is Belial Sigma (proxy Sigma) that was seen as the villain.
