As a warning I don't put spoilers on unconfirmed, probably wrong, theories.

The Omega symbol has shown up a lot this year (and a little bit last year) which leads me to believe an appearance by Omega himself is not far behind.

If he is in fact alive we know that he is incorporeal at the moment and that he hates the doctor. Therefore I think it is logical to consider that he may be behind Melody's abduction.

We have been assuming so far that the Anglican army worships the same God that is associated with the church in this millennium. What if, instead, the Anglican church of the 51st century (and the Silence) worship Omega.

That would explain why they consider the Doctor to be an enemy of God. It would also give possible explanations to why they want Melody, why they wanted the suit built, and who killed the Doctor.

Both the suit and Melody (because of her Time Lord DNA) could both be possible ways for Omega to become physical. (Omega would certainly be a weapon used against the Doctor) Therefore who killed the Doctor in TIA could be Omega in the suit. Of course it might also be Omega possessing Melody inside the suit.

It's the best I can come up with right now. I'm probably wrong, of course.

This theory would also explain the voice in the Tardis in last years finale: Omega.

A lot of people have viewed this, but so far I have gotten no feedback. Is it a solid theory? Is it impossible because of something I'm missing?

I'm not sure about Omega anymore, but when I heard that Melody had part Human + Timelord DNA, and that she was going to be used as a weapon...

I thought of Omega

Nice to know I'm not alone. I wonder if a large reason for a lack of response is because most newer fans don't know who Omega is.

That's what some of the older fans have told me; that Omega can't come back because he has a large backstory and younger fans won't know him. They didn't know the Daleks or the Macra either, so IMO there's every chance that the big cheese will appear in the future.

I know who he is, and I'm just 19

I've been of the opinion that Omega is the 'big bad' for some time now. He would be a prime candidate for being powerful enough to control and destroy a Tardis, as for why who knows. The Moff has stated and it has been seen that all the 'enemies' in his tenure have a reason for their actions and not just pantomime villany. So why destroy the Tardis just to kill the Doctor? Seems a bit long winded, maybe destroying the matter universe would have brought the anti-matter universe to prominence giving Omega some kind of life again...

Also (and I mentioned this in my other thread) why take the Tardis to 26/06/10 first?

The first episode I ever saw was Rose and the only classic story I've seen the The Caves of Androzanni. However, I have become a fairly obsessive fan during the SM era so I have spent countless hours reading up on the lore of the show. I had read up on The Arc of Infinity and Omega the night before AGMGTW aired (which I had to see online because it doesn't air here in the states until sat.) so when I saw the episode all of those theories just kind of clicked.

Omega has been thrown about as the next potential super-villian for more than the past year. I think people aren't responding because there's nothing new to say, I'm afraid.

That is the best theory regarding a motive for destroying the Tardis that I have heard so far. You are helping me become more convinced the big bad is Omega.

I'm sorry I missed your other thread. If I saw it I was far too sleepy to remember. Do you have any idea about 26/06/10? I can't think of any reason that fits.

I guess it's my fault for not digging deeper into older posts. I'm fairly new to the forums and I have seen a couple people mention him in the last day, but no one I saw mentioned the possible religious connection to the army.

It's been said in other threads and I think that the character development is pointing in the right direction. I've a feeling the Omega won't be the big bad but it will be Rory!!!

I was thinking that because this was the day of Amy and Rory's wedding ( I think it was anyway, been a while since I watched it) and Melody seems to have been concieved that night then it was to stop her being created... but that doesn't pan out because if your aim is to destroy the entire universe then location really isn't an issue, and again why destroy the universe just to kill one person.

So I'm afraid I'm out of ideas there...

I'm sorry for re-posting an existing idea. This really is a great community and I thank everyone for their patience. If this had been an American site I would have gotten flamed and trolled 8 ways from Sunday

I'm 20 years old so obviously don't remember Old Who - ergo I haven't heard of Omega apart from all the threads saying "The next big bad is Omega". its no different to the Master coming back (i'd never heard of The Master before Utopia)

He'll have to have a new costume though, just searched Omega in Tardis Wikia and he looks rubbish (sorry If I offend Old Who fanatics, but its the truth )

I've been touting that same theory since the end of last season. There are more facets to my theory though - and more clues: how come the Alliance think only the Doctor can pilot the TARDIS, when we know his companions have been able to? Who could get the Alliance's individual members together to talk?

I felt it needed an overlord to bring it to fruition...

Haha! It has been known to happen here... I think that because you joined in May, it's unlikely you could have gone through all the back pages of posts!

Oh, and welcome!

Many of the old costumes (and dare I say it: Monsters) looked rubbish! The old silurians aren't a patch on the new style...

And there's been a major discussion brought up every now and then about whether the old-style cybermen look better than the new astyle (fwiw, I think the latest versions are much better looking... )

That makes a ton of sense. Has anyone brought up the possibility of Omega being the God figure of their religion yet as far as anyone knows?

Nah, Omega looked ridiculous. No two ways about it...

Anyway, no need to worry about posting a theory that's been proposed before. I just thought it might explain why it wasn't getting more attention. Personally, I think it's something a bit more complex than "there's a single bad guy behind it all".

There has been possible linking with a stylised Omega symbol being part of the clerics' military outfits (here shown on River's arm). It does also seem to have two vertical lines, which some posit mean the roman numerals for '2' - leading to it meaning Omega 2: the return of Omega (but in a second incarnation).

Or, as Moff is wont to do - it could be leading us up the garden path, by him purposefully inserting tantalising glimpses like these that will never mean anything more than a nod to long-term fans!

Of course, the Alpha and the Omega are religious symbols, and the military was just the church taking it's next logical step (they've moved on, I think 11 uttered in the Angels 2-parter last series...).

According to the DW wiki, Omega was meant to appear instead of rassilon in TEOT but RTD changed his mind for unknown reasons. Didn't RTD and Moffat have a discussion before RTD wrote TEOT?

Also, speculation about Omega has been everywhere on the net but where did it all start in the first place?
