Yes but he might not identify it as an enemy at first since he does not look like one. How high in the skill chain does Beatrice sit ?
should be around Echidna's level
That's only for the incorporeality, what I was talking about was the intangibility.
Incorporeality is literally a superior form of intangibility

If your true body can avoid being hit by normal physical attacks then its intangible but if your body is itself exists non-physically then its incorporeality
Yes but as a said there's nothing that tell me that Beatrice can destroy spirits and it's not on the profile anyway.
Puck killed Melakulera with magic and its been stated that there is a chance for puck to lose beatrice
Beatrice would also give Roswaal a good fight and we know he can kill spirits as well
in fact, all of this is on the spirit blog. so it IS on her profile
Yes that part may work.
Yes but in this key specifically she has been hunted down for two years by the government, constantly fleeing and fending off attacks. Barely getting any rest and harrassed by otherwordly entities when she was not fighting. Plus by SBA:
"Each character will view their opponents as enemies, who they have to assume wish to cause them severe harm such that losing could have any range of dire consequences."
So it would still be hell to pull off.
From the profile: "Aiden has his own free will and doesn't necessarily have to do what Jodie tell him to do."
Plus he have been hostile to people like Ryan which Jodie fully trusted. He might have stopped had she begged him but not in a context where he is aware the other side is an enemy.
i will drop SI because Subaru wins regardless due to the speed gap
That's not true, Beatrice have:
Which mean she lack:
- Incorporeality (A Spirit's true form is their Od- the core of their being, which is the owner's life energy and synonymous with the soul[2]- and their physical body is merely a manifestation created by the Spirit using Mana)
- Immortality (Type 3)
- Regeneration (Low-Godly; Injury does not exist for Spirits,[4] they will easily recover from any damage to their Mana-based manifested forms, and they can only receive real damage if[1] their Od- the core of their being, which is the owner's life energy and synonymous with the soul[2]- is targeted)
- Body Control (A Spirit's form is decided upon by themself, thus they can change their size[6] or even reconstruct their own body at will,[7] removing any previous effects, which can for example be used to instantly make themselves sober)
- Possession (By gaining permission from someone or by forming a contract with them, a Spirit can possess their body,[1] as long as the terms of the contract allow it)
- Intangibility and Invisibility (Spirits are able to dematerialize,[13] and while dematerialized, a Spirit is invisible[14])
- Spatial Manipulation (Spirits can manifest themselves anywhere as they traverse space[15] itself)
- Limited Fragrance Manipulation (Spirits don't have scents[16] like ordinary creatures, thus they can avoid being detected by the noses of Dragons)
All of that comes from dematerialization of spirits
about the possesion thing, in ReZero there is basically a meter which allows a person to be possessed/be able to hold contract with spirits
the more affinity you have for spirits, the more likely you are to be possesed but this is also the reason why if someone is in contract with a spirit they cannot be possesed. This holds true in this regard as well.
Its stated she get tired faster with magic not that she can't get tired at all, as soon as she doesn't have the stamina to run anymore she get one shot.
Beatrice will not be running, she can fly...
and the key you are using for her literally has the both of them soloing an army of undeads without tiring for HOURS, and to make it worse you have the tier 9B Subaru with his dragon blood leg which is basically an untirable leg that can regenerate
And they cant do nothing if Beatrice just blitzstomps them both at the beginning of the fight
Then a CRT have to be made because it's never stated on the profile:
- E・M・M: An original "absolute defense magic" co-developed with Beatrice. Using Yin Magic, Beatrice interferes with the space-time around Subaru, side-stepping their plane of existence, and while they can't move during activation, they experiences no interference from outside the barrier. It is similar to Regulus' Authority of Greed but doesn't have the same risk, and can be used until mana runs out.
For a lot of these arguments, a CRT need to be made before they are valid.
its not that they can now suddenly "move" with EMM but SUbaru can time it well enough that if he is already in movement he will be able to activate it and combo with it without any issues
