Ella also mention that nyx surpassed her monster.
I didn't say that she cant recreate the body, just not from nothing, if something burn, ashes are left and then she restore the body from that, i dont remember if they are exemple where she resurrect people without their body of if it's mentionned somewhere.
During diamond battle, she only start to fight when a third of the people she marked are dead and ask nico to send her in" it sound like she need the body to me and we still have the exemple from the gorgon, if she petrified someone, Nyx cant restore stone to flesh and another exemple are Christie, we now that Ella had a similar securities for Christie and Emily but Ella couldnt resurect Christie after mc had devoured her no? (didnt play that part because i like Christie )
just that every element that we have so far point to her needing at least some leftovers of the body but i could be wrong of course .
but they are still a lot of similarities with memory and how that part of Nyx power work.
Yeah, I edited my post because I misjudged your point. There are a few reasons why I think Nyx can resurrect from nothing.
1. Duncan is willing to die to give Nico the chance to take out Ella and he has mentioned numerous times that he is protected by the Reaper. Duncan is an old member of Nyx's team and he probably knows exactly how this works. Also Nico is way too quick to accept his judgement without even a goodbye when she considers herself better than Ella and is already empowered with Clark's power. Nico kills by transporting her victims to the sun. I don't think you can come back from this.
Edit: To add to this, Nico may be able to just transport Ella to a faraway planet and then just retrieve Duncan's corpse . However I doubt that space can actually kill Ella or most level 5s for this matter. They don't need to breath, Ella's body is significantly stronger than Nico's who is confirmed to be able to survive it for weeks, and high level Superhumans don't actually need propulsion to travel, they can just manipulate their energy. So Ella will come back, perhaps in a year, but she will come back. And even if she can't, Hex can do it for her.
2. Ella has probably marked Christie and Emily. However those 2 are just human. If attacked by a monster, it's quite likely that they will get eaten or their body will be left in such a stated that it will be hard to find even a small piece of it. And that's without considering what apocalypse Ella will bring to Earth.
Both present Duncan and the victims of Gorgon have a common point. They are actively affected by someone else's power. Perhaps that's the reason why she can't bring them back. Also I'm quite interested in why Nyx doesn't just use her death ray on Duncan to kill him. If that's her main offensive power and it's confirmed that he can ressurect the people she personally kills, why burn him down in the first place?
Anyway, that's the reasons I think that she is capable of restoring someone from nothing as long as she has preserve their soul. But you make a good point. The Gorgon one is very interesting and it's not like my arguments are fullproof.
However my suggestion of Truth still holds because even if she can't restore a body from nothing, she seems capable of restoring it despite the injuries suffered, which is in line with what Eisheth can do. It does open a possibility for Creation though, similar to how Deryl can regenerate flesh with his Elixir.
Dunno what are you smoking, but Nyx was stated to be able to nullify the energy of Tiff and Michael during their evolution. That's a Dark trait shebang. Her resurrection power stems from Memory (monster fought by Niko was mostly pure memory judging by the connection displayed), also Dark is stated to be able to imitate things.
I mentioned this about Nyx and left the chance for Dark open, but it's not as clear cut. Nyx stops Michael's energy but not Tiffany's light. She only drains Tiffany when she catches her in her hand. This effect can easily be attributed to Power, similarly to how Michael is capable of absorbing energy and draining other Superhumans. Michael is just a level 2 so his draining effect wouldn't be that amazing anyway. Nyx on the other hand is an extremely advanced level 5, so if she has a similar power, it would be easy to apply it to Tiffany.
Dark is not out of the question, but since she has some similarities to Michael, I'd rather support this angle.
As for the Memory monster having a Dark component for the imitation, sure, it's a possibility, but the monster report mentions simple things like making Armor and a Sword from shadow material. It's quite a jump to extend this to using someone else's powers, especially when Xanthe sets a different precedent.
I won't rule it out completely, but I want to see how Langdon's powers work, which I attribute to the Dark too. If Langdon is capable of using a monster or superhuman body to it's full effect, then perhaps there is more to Dark than what I think.
So I will preface this with an explanation that of the twelve primary abilities, Truth seems to be the most esoteric. Unlike things like Memory or Body which are more tangible and explain themselves rather easily, Truth appears to be to be much more... poetic? Flowery? Not sure what the best word for it is.
Deus feels like Truth to me in a few ways. Mentally, I have tied together the future sight and his divination of other people as part of the same ability. Think of his future sight as something along the lines of "It is true that if I drop a rock from my hand, it will fall." When he looks at someone and learns all this stuff about them, he's learning all of the true things about them. He was able to immediately understand that the MC was visiting him in a dream, and unlike Michael, he didn't appear to be in any sort of special circumstances that would've allowed him to "come to realize" he was in a dream. In a way, its also something that can extend to his attacks like "It will be true that a light beam will cut this person in two." though this is a bit more of a stretch on my part.
Another point that is more personal opinion than anything else, is that Truth feels much more interesting if you consider Deus to be HERO's secret weapon. Memory, while very strong in its own right, feels less like a grand reveal than someone who absorbs truth.
Hmm, it's obvious that we view the Truth trait differently. In fact we seem to view it completely opposite.
To use your own examples, I think the Truth power is about letting the rock drop and deciding that the correct way to fall is up instead of down, which is probably why Eisheth has telekinetic powers in the first place. Inside Eisheth's domain, not every action has a reaction, rocks fall to the sky, not to the ground, Death is just a suggestion, not a fact. It's exactly what she says, "I decide what is Truth".
Your idea seems to me more like determinism. I like it but I can't observe it in the game in a form that will persuade me that's the case.
