I guess I'll repost my proposal from before.
God tiers (Low 1-C)
C'iel, Gaira, Beryls and Shajads (For obvious reasons, although none of these have a profile yet.)
"Possibly" rating for Pillars of Souls weapons for hypothetically being able to harm Beryls/Shajad, though this hasn't been put to the test.
Top Tiers (2-C)
The Powers in the Shadow, Rah, and
Baal for their own feats.
Nemesis, Eljared, and Lazarus for being confirmed by WoG to be the most powerful beings in Gaia. Amaterasu for also being a potential candidate, and Bringreus for the same reason as Amaterasu, as well as Being one of the top 5 Messengers alongside
Baal,
Ergo Mundus, Yami no Tsubasa, and The First Chaos.
Varja for being literally Amaterasu but twice as strong.
The Drago for Erebus (Shajad) being convinced that no being weaker than a Shajad or Beryl could kill it. Tawil for being comparable to The Dragon,
Rudraskha for being weaker than both, but still likely comparable, as well as being stated to be powerful enough to be "King of the Aeons" and compared to "a deity".
Omega (Anima: Beyond Fantasy) for being seen as a major threat by The Powers in the Shadow to the point that they needed to seal him away because fighting him would have revealed their presence to the world. It's also stated that not even an Aeon would have the power to confront him, which includes the likes of Tawil and The Dragon. (Fun fact, the guy also has a Pillar of Souls).
Likely
Filisnogos for being mentioned in the same statement above regarding Omega and the Aeons, implying that it's comparable to them in power.
Etheldrea and
The Nameless for helping to defeat Baal in the past, and being comparable to each other and Ergo. Elienai for also helping against Baal and being comparable to Ergo (but no profile).
Ergo Mundus for being compared to Rah, one of the "Top 5" Messengers, and having power valued by The Imperium.
Nascal Mehirim for fighting Ergo,
Jonathan Kappel for fighting Ergo and being considered one of the biggest threats on Gaia by The Order of Nathaniel.
Malekith, Prince of Crows for being stated to be comparable to Ergo, and later proving this during their fight in Gate of Memories.
Tsukiyomi (no profile) for being weaker, but comparable to Malekith. All of the Kotoamatsukami for being stronger than Tsukiyomi, and helping to seal part of Varja's power before he became Amaterasu. Yagarema for being comparable to the Kotoamatsukami.
Likely
Kujaku Hime for being the best fighter of the Asakura clan. Said clan being responsible for guarding the Magatamas which hold the other half of Varja's power, it's likely that they can stand up against the stronger humans in the verse.
Kisidan (no profile) for being comparable to Malekith, and likely the strongest human on Gaia. Possibly
Elisabetta Barbados for Kisidan stating that she could be his equal with a bit more training.
Griever for being weaker but comparable to Kisidan, and likely stronger than Elisabetta.
Yuri Olso for being comparable to Griever.
Druaga for fighting Ergo and being comparable to Elijah Giovanni (Elienai's fiancee who also helped against Baal, being the one who specifically killed its avatar).
Ra-Me-Tek for fighting
The Nameless.
"Unknown"
(Yes that's her "name") for being comparable to Nameless and later embodying The Seed of Baal.
Romeo Exxet for being weaker but comparable to
Ergo Mundus.
Red Lady (Anima: Beyond Fantasy) for being weaker than Ergo and Nameless, but somewhat able to keep up with them. Also provided support to Romeo during his fight against Ergo, and delivered a fatal blow to The Nameless in a surprise attack.
The Colonel. Should be at least comparable to
Yuri Olso, and it's stated that "no man or immortal can touch him", implying that he's one of the stronger characters in the verse.
Alastor should be comparable to The Colonel.
Matthew Gaul is "one of the most fearsome people in Gaia", and superior to both
The Colonel and
Yuri Olso.
Marchosias Lostaroth, as a High Inquisitor, should be at least superior to the likes of
Lady, and probably at least somewhat comparable to
Romeo Exxet.
Ophiel casually slaughters High Inquisitors, putting him above
Marchosias
All the other Messengers for being considered to be "the 21 greatest threats to the world" by The Church of Abel, as well as being stated to be above the likes of
Lady.
Likely
Zhoul Orgus, as dragons grow in power with age. As a Dragon of Gaira, Orgus has been around just as long as Svalkislavos (one of the Messengers), and was even granted additional power by the Shajad Noah.
Possibly
Gurmah-Gharus, as it should likely be somewhat comparable to the
other three sleepers.
Behemoth (Anima: Beyond Fantasy) is referred to as a "destructive force whose power is equivalent to that of the oldest dragons", which obviously includes
Zhoul Orgus and Svalkislavos. As " supreme sovereign of all the beasts that walk the earth", should probably at least be comparable to
Gurmah-Gharus.
Possibly
Seraphim Potestas. Their "extraordinary power" is "difficult to measure", and powerful enough that they're believed to be weapons created by the Beryls themselves (though this fact is unsubstantiated).
(7-B)
Varuna for his own feat. Fellow High Elder Elementals
Agni (Anima: Beyond Fantasy),
Arias Vayu, and
Chtho scale for being comparable in strength, along with
Elhaym and
Lord of Darkness.
Seraphim Potestas is
at least this strong. As the highest grade of light elementals, they should be far superior to
Elhaym.
High 8-C
Ice Maide for her own feat.
Etrien Gnosos for also being greater elementals.
Shadow Master for treating "powerful elementals" as fodder. They should be at least much stronger than Ice Maiden.
The Machine supposedly has its own universal feat but it needs to be translated.
Everyone else either doesn't have enough information for me to make a non "headcanon"-ish case for scaling, or I couldn't find anything about them to begin with.
(There are probably some people I'm forgetting, but Antonio can point them out.)
