1. Michael Roa Valdamjong- remake ver (Location: Misaki)
The probably win due to the nature of how limited Roa is but at the same time, I'm not sure since Roa gets some major upgrades in keeping his Grand Magecraft despite losing his BS regeneration so it's a toss up considering how strong those upgrades are.
2. Gilgamesh (Location: Fuyuki)
They get murdered. Gilgamesh scales himself to the opponents he faces and they ain't no Shirou so he won't hold himself back due to pride either.
3. Dust of Osiris (location: Emerald Table)
I honestly don't know this one as Dust of Osiris is out of my knowledge of the Melty Blood series.
I do know she's capable of some nonsense but I don't really know the scope of how far it goes.
4. Lion King (location: Camelot)
They get bodied like a motherfucker. The Lion King's Rhongomyniad is compared to Morgan's which could have destroyed all of Olympus and the Tree of Emptiness at the same time and explicitly was able to overpower Wodime's Animus Animusphere which is compared multiple time to Large Planetary+ attacks and it moves at FTL due to the sheer distance it crossed(I won't say MFTL because that's really stretching it)
5. CCC Kiara Sessyoin (Location: Moon cell)
They get bodied by her hax before they even fight her
6. Arjuna alter (location: Indian lostbelt)
God Arjuna just laughs off everything they do. His sheer Divine Protection is practically insourmountable to them unless they truly find a way to make him weaker there, he won't even need Mahapralaya to kill them considering the amount of shit he has which can do the job easier.
7. Cernunnos (location: Britain lostbelt)
Large Planet+ Destroying Curses, can literally spawn wherever he wants and are in the shape of a massive tree that looks like it can trump Mountains. Can take 13 Rhongomyniads/Excaliburs to the face and not even die from it and can regenerate all of the damage in minutes...
8. Koyanskaya- beast IV L (location: Tunguska)
They would hilariously have the best shot here but would still lose because they would circumvent most of Koyanskaya's shit due to not being Human but still die due to her sheer energy payload and her Meteors.
9. ORT (location: South american lostbelt)
Yeah, they just die...
ORT took a
BLACK HOLE(Yeah, it was confirmed in Heian-Kyo U-Olga Marie can literally conjure Black Holes, genuine Black Holes, as easy as she breathes) to the face and just shrugged it off and is atleast estimated to be 10x stronger than U-Olga Marie... and it's highly implied it was at it's weakest state even then.
