Since I didn't go into the topic before when talking about Beast II avoiding it, I want to see the opinions of people. Some people claim that Zeus is superior to beasts.
For me, and what seems to have been said, I don't think Zeus is on the level of a full beast.
Before we get into this, we know 100% from LB 5.5 that Goetia and Alien God are Superior to Zeus and Chaos. As they state none have been as powerful as the two.
Now lets get to the other beasts
1. Beast II
2. Beast III R/L
3. Beast IV and IV/L
4. Beast VI
Now before we get into this, we are going with Lostbelt Zeus, but it will be in a neutral zone. We can talk about the results if they weren't in a neutral zone and instead were in Olympus, or in a reality marble or singularity. But for now, we will go with their base to base.
Zeus The King of Gods
If we go by Zeus' abilities, he is mentioned to be below Goetia, even having his creator Chaos not be mentioned to be above Goetia.
But we also know Zeus and Lostbelt Kings are strange in their scaling, outside of their lost belt they aren't as powerful as being noted as a "Lostbelt King" which means you gain authority over that reality.
Let's go with Zeus who has absorbed all other functions from the other Gods, in the battles because they are neutral zones he would not be burdened by Olympus. But he would also lose anything from being a Lostbelt King.
Beast II
The Beast of Regression is the second beast Chaldea has seen. (Fou is the first). She isn't mentioned much anymore, usually, they compare everyone to Beast I. The last time she was mentioned was by Mash when talking about Echidna seeming similar to Tiamat.
Tiamat is noted by the Lion King as being equal if not superior to Beast I, though some say she was only on the level of the False Grand. Though the Lion King was noted as having "acquired a level of perspective on par with his, understanding both his ideal and his purpose" even knowing secrets about his temple. The Lion King knew about beasts which isn't surprising because Odin knew about beasts.
We know that Beast II's authorities are on a level before Genesis, as stated by Quetzal. She is one of the driving forces and powers in Mesopotamian myths, with authorities that we may not know of but likely have stemmed from Tiamat and Abzu. We also know she has Potnia Theron allowing the endless amount of magical beings to be produced, those on the level of divine spirits and back before she became a beast even on the level of gods. Her main authority, one noted to be on par with the bands of light, was the Sea of Life. The Sea grants her infinite magical energy from True Ether that predates Genesis. Creatures corrupted or created from the sea possess high-level skills and depending on when they are formed can rival demon god pillars, or be born at the level of divine spirits.
If we use Anime, Tiamat's magical energy surpasses the Lion King's by 300x. With even the powered-up Femme Fatale being nearly 4x above the Lion king.
We know that the beast has been shown that they aren't able to die no matter what, possessing multiple immortalities stacked on top of each other. Possessing the ability to not die as long as there is a living being in the realm she exists within, she lacks the concept of death, so even if you get the first condition, you can't kill her. Lastly Immortality of the Beast, shows that beasts even if they "die" losing their immortalities, their bodies are destroyed and all. They don't die; seemingly as long as humanity is a thing, the beasts will continue on.
There are two ways we can take Zeus Vs Beast II by.
The way we saw her in Babylonia
The way a fight like this would actually happen
If we go with the way in Babylonia, Tiamat would not have a mind and would be sealing her abilities.
If we go with it being neutral, Tiamat wouldn't seal herself against Zeus nor let her mind be destroyed on purpose.
First off, going with Babylonia. Tiamat won't be distracted by trying to destroy Uruk, in fact, with Zeus becoming such a big threat, her attention would be squarely on him. Likely not sealing herself as much, as Zeus isn't one of her children.
Now people who make debate of Zeus Vs Beasts all say "Tiamat can't do anything her output is too low." Her output is at a minimum on the same level of Goetia, she may not send an instant powerful beam as Goetia can, but she isn't going to stand there doing anything.
Zeus' flight will spare him from being swallowed up by the sea, but eventually, the Lahmu being born from the sea will simply start flying and attack Zeus. He won't be taking much damage from them, though it's not as if he is gonna be uncontested with firing lightning at Tiamat. Tiamat would eventually simply fly as well, and no, Zeus isn't "a faster flyer" Tiamat is noted to go around the stars as well.
There are those who say "Zeus will place the authority of death upon her" Hassan needed to release his Grand Status, which gives an extreme boost as shown with Orion.
Though if we are taking Tiamat without a mind, Zeus is likely capable of Destroying Tiamat's body. We know that Zeus is capable of destroying the Bodies of Gods, though if Zeus doesn't destroy Tiamat quickly enough, he will be overwhelmed eventually. As Tiamat would simply be raising her energies and modifying her body.
Though if we go by the fact that Tiamat can simply spawn her sea, which requires the bands of light to destroy making Tiamat's body on par with Chaos who was stated to be able to do the same thing.
Zeus would eventually be overwhelmed.
Let's say "Tiamat isn't on the level of Goetia" fine, we know she is far, far far superior to Goddess Rhon 300x in her Titan form. Goddess Rhon was comparable to Morgan's Rhon, which surpassed Kirschtaria. Kirschtaria is above 10% Zeus and likely would be comparable to at least 40% Zeus, as Zeus had to raise his abilities to survive the attack of Kirschtaria. We can even say he was only 11% of Zeus' abilities, it wouldn't change anything.
Going by the numbers from Tiamat being scaled not from Goetia but above Goddess Rhon, she still surpasses Zeus.
If we go with Tiamat, who has a mind and isn't showing mercy to Zeus, well it would be a wash. She would go to whatever level she needed to, using her authority using the mind of a Goddess instead of just using them by instinct.
Beast III L/R
Kiara and Kama,
Let's go with Kiara first, Zeus has Ruler Class designation so he instantly loses to Kiara. The end focus.
Alright, let's actually go through it, if we go with Zeus not actually being a Ruler. (Which he is as stated by Chaldea) In a Neutral Zone, I think Zeus would be superior; Kiara has still noted as a weak beast. If she can't use her hacks against Zeus, then she doesn't have the firepower to destroy him.
Kama, other than Zeus enjoys the fact Kama gives all forms of pleasure. Outside of her singularity, she is screwed since she isn't a full beast yet.
Beast IV and Beast IV/L
Now let's go with Fou and Vitch
Fou, we don't know Fou's serious mode. At most, we know a Fou who doesn't own the beast class and takes 7 counter force guardians. A serious beast fou might be stronger than Zeus, but we don't know.
Vitch is straight-up weaker, not being a fully developed Beast, Ibuki isn't afraid, and they don't show too much fear of Vitch's beast form. Saying she started her plans way too quickly.
Beast VI
Now we have 4 beasts that represent Beast VI; now, let's say they all scale similarly. Each one of them would crush Zeus, currently, Whore of Babylon is only person who has been stated above Goetia (which people don't argue about).
If we use the fact Beast 6 L/R were one being, and if they scale anywhere near Whore of Babylon. A true form of Beast 6 from L/R would be crazy and far surpass anything else we have seen.
Whore of Babylon being above Goetia is far above Zeus, there aren't really many reasons to go on with them.
Bonus Round
In Zeus' Lostbelt,
Tiamat would eventually corrupt the lost belt and defeat Zeus
Kama and Kiara get destroyed
Vitch and Fou are destroyed
Whore of Babylon wipes out everything
Round 2 VS Chaos
Tiamat, if she scales to Goetia, she defeats Chaos if they ever encounter each other. Both can cause Space time Quakes, so it's not as if Chaos' NP would be unique.
Kama, Kiara, Vitch, Fou. Well it's obvious
Whore of Babylon, it's the same.
Now
If you disagree, give a reason and your reasoning. There was a lot to say about Tiamat Vs Zeus, 1, because that was going to be my original post 2, There are some people who say "Zeus crushes".
If you want me to bring the "where are things said," I will.
Anyways bye
