The flower is actually >>> the queen beast. Zero and Mikhail killed the wyrm (and it was boosted by the power of the song), they just needed the watcher Decadus summoned to keep it from teleporting everywhere, the wyrm Caim and Angelus killed isn't as strong. IIRC from Drakengard 2, everyone got their shit stomped by Caim, there was no way to defeat him to the point he himself had to let them kill Angelus to defeat him.
Also, Michael is stated several times to be the strongest dragon, Gabriella confirms this (kinda) and he got rekt by Bartas and Gabriel, Mikhail killed Gabriel in 1 ending and kept up with him and the flower in the last ending. The canon ending has him dying to poison and then dying again because of the Pact Partner rules.
The other stuff from D2 I'm meh since I don't remember much from it.
IIRC Manah is like the emissary for them to manifest (like the power of the song was to the intoners), it is not that she is possessed by the QB but rather she acts like the conduit and once its broken they can flood the world. This happens in the utahime 5 when the intoners die and the black flower ressurects them, the angels start flooding and destroying the world. Still, resisting possession is just that, a resistance and not power and I very much doubt she will scale to brother One, let alone above him. His words are something like "This song is not even a fraction of my sister's", his power as a second generation intoner is massively outclassed by the sisters since they had the flower. Manah is like his grandkid and his twin brother is the one that got the magic potential, not her.
We also need someone to either play Reincarnation or get playthroughs and files since it devolves in different worlds and some other stuff like that.

It should also be noted that Manah should compare as well. Nowe states in ending 3 that Manah's power is energising him, and his tone implies it's significant. In addition, when Nowe and Legna were beating the Bone Casket it took Manah and used her power against them, and in the end she destroyed it from inside. Keeping in mind this is adult Manah who has resisted the possession of God, so she is likely stronger than her kid self. And It's also notable that Nowe only says Manah is energising him in the ending where she has absorbed the Bone Casket, indicating she gained power from it.
When it comes to Manah, we should also consider that she seems to be possessed by the Queen Beast. It emerges only when she is killed, and in Drakengard 2 ending 3 when the Bone Casket comes at her she says that she recognises the being behind it, that its "womb" was warm, and that she remembered it well but wouldn't become one with it again. That possession, and anything it left behind afterwards, might already result in more power than brother One's words would imply. It's clear kid Manah isn't that strong, but adult Manah, especially in ending 3, should be.
I just sent my friend a message asking them to look for as many Drakengard and Nier guides as possible. I also told them to look for the tales and side stories other than the ones I already got from them. I can send you those via email if you like, but I don't think they'll help. I also mentioned SinoAlice to them.
