So, I have the Core Book and Gaia and I can't find any references to Omega in either of them. I've only perused the fluff section of the Core and Gaia, but Omega did not catch my eye. Can someone please tell me? Thanks.

He is found in Those who Walked Amongst Us. The bestiary.

Ah. Well, there's no way I'm getting that any time soon. Could you please tell me a little about him? All I could find on the net was that he's supposed to some sort of "Harbinger of the End Times". A little more info would be good. Origin and stats, in particular.

Seriously just get the book, their is way to much information just to share, plus it wouldn't be fare to share such stuff.  Just buy the book yes its expensive, but its well worth the money to further your games.

 No kidding! Every book is chock full of fluff and stuff.

Just to make it more interesting Omega is so named because it is the creature that will eventually destroy reality. So ya, get the book.

 to be brief:

Abel was dealt the final blow by an undefined descendant of Andromalius (last Emperor of Solomon), who thanks to the machinations of Millenium had come into possession of a Pillar of Souls (a weapon from a bunch of 20 created by Imperium with the objective of creating the perfect weapon to destroy Shajads/Beryls/Gaira/C'iel). The Pillar of Souls peculiarity is sucking-up all Gnosis and powers from the target, so it can become stronger through ages. Now when the Pillar sucked the AWESOME Gnosis of Abel (supposedly a Protodeus of high level from Imperium), the nanomachines inside the blood of Andromalius' descendant went completely mad and somehow interferred with the whole stuff.

As a consequence the unnamed guy is turned in a monster of pure power and madness, which creates a completely new pocket-dimension for itself, where it resides. Sometimes it sends avatar into Gaia (The Shadows of Omega). Imperium so far has been unable to go and collect the Pillar of Souls possessed by Omega, which is VERY VERY annoying to them.

Actually, the whole creation of Omega was a twisted plan by Millenium exactly to thwart the Imperium by putting the Pillar of Souls out of their reach.

It's no wonder if you consider that Millenium later helped both Rah and Eljared in their plans...both great opponents to the Imperium.

My belief is that, considered the mentioned powers, Millenium is actually the Avatar of Uriel, which fights against Imperium because ultimate freedom for Gaia would be breaking the influence of Powers in The Shadow. I wouldn't be surprised if she also manipulated so that Iscariot came into possession of Solomon's 30 Black Pieces and knowledge of Imperium manipulation so long, which was another thing Imperium did not exactly wish for.

Perhaps I went a bit out of topic, but this fluff is very interesting so I hope I didn't troll your topic anyway.

I would get the book if I could, guys; just really short of cash at the moment. I intend to get it as soon as I can. So, thanks, Elric, for the info. I can work with that for now. The speculation about Millenium being an Avatar of Uriel is really interesting.

I thought he was trapped in that pocket dimension by the same people that gave him Longinus to begin with. Because it became a threat so powerful that no-one could destroy it, just trap it. Also it's Shadow (avatar) that's floating around is looking for a way to free it, so that it can destroy existence.

I suggest picking up the book, though you might make your own Omega, or pull something from a FF game. It has multiple 'incarnations' that you face in a battle. First you take on Magic weilder, and when that goes down you face it's real self, Mr. Ki. But there's a lot of other fun stuff in Those who Walked Amongst Us part 1, than just Omega.

Omega is a level 16 Technician that does not break the rules of the game. He can easily be defeated in both his forms. I thought he was supposed to be an all powerful thing too, even the description of him gives that impresseion. His stats are just extremely disappointing.

...Omega is a serious threat. Just saying. And his stats are way higher in general than you're going to get on any PC at 16th, or even 30th level.

Not to The Imperium. I did the math, a group of level 10's can kill him without trouble due to mass combat rules granting +150, assuming they have Gnosis of 15+ (Omega gets a bonus due to high Gnosis) and 1 level 10 Wizard can just become a god and beat him down if they needed to. Of course, as that I always play wizards and know wizards inside and out, all my plans involve killing him with magic by removing his Supernatural Powers, decreasing his Gnosis, destroying his weapon, and then killing him, all this requires is a Wizard casting High and Divine Magicks, which The Imperium has.

Remember Imperium is a large group of level 10+ people with technology, magic, and technomagic that makes The Empire of Solomon looks like "barbarians". All they need to do is drop a nuke, what scares Imperium, from my understanding, is not Omega. They are afraid of whoever made Omega.

I thought they feared him too, but the people at the official forum corrected me.

 I can see your point there. Not overly familiar with magic beyond the basics. But Anima has numerous systems. I think perhaps the Gnosis tackling issue should be resolvable in more ways that just using magic though.

 A level10 wizard must be allowed to cast in order to make all that stuff...and it's not like Omega is going to relax while you accumulate zeon. He's pretty tough and the imperium must be careful sending level10 protodeus against it, because anyone fell by Omega turns in more power to him (due to the pillar absorbing the Gnosis and stuff...).

Anyway, the Imperium right now considers that Pillar of Souls out of reach, which is somewhat bothersome to their plans. Besides, if I'm not mistaken spells allow MR checks most of the time...what if Omega passes those?

Two things;

1) By the time the level 10 wizard I am thinking of is actually fighting Omega he is considered a level 14 with 2400 DP, Gnosis 45 (giving +10 opposed checks against Omega), 20INT, 16+POW, with High and Divine Magic at his disposal, and would need the Metamagic ability Added Maintenance. I said a level 10 wizard can become a god and fight him, if they do not do so beforehand and fight him as just a level 10 they will lose.
     There are many, many ways to make him stronger (such as existential loop), but this is assuming a level 10 that was not designed to be overpowered at first. Yes, you can transform a standard level 10 Wizard into this without much trouble. If a player wanted to do this I would allow it, however I would not allow them to stay in this form after defeating the threat that Omega poses. Basically this should only be allowed as a last-ditch, "we failed to stop his escape so we need something that can beat him down" strategy, and should probably have some major cosmic retributions in its own right.

2) It is true that Omega has good resistances, but he has a 99% chance of failure against a group of level 10's (due to the +50 MR to their spells from mass combat spells) and an 80% chance of failure against the wizard (unless he uses Voodoo in which case 99% failure with some prep). In either case that is at best a 20% chance of resisting. Unfortunently his Omega: Lord of the Infinite form does have Chaos Meister ability and really high defense, which does cause some problems if he activates it... Him blocking the spell is more of a problem  than the MR check.

Um...so your entire  strategy is based on using optional rules, and declaring 'mass combat' on a single big bad with your party. Since when does fighting one person count as Mass Combat? And who would allow that?
