Minerva has not gone through formal power testing of any kind, so all information in this assessment is based on observations.
Note that these 'observations' are primarily her own damned cameras.
In addition, there is no evidence that Minerva is actually a parahuman. All of her abilities have been demonstrated, in whole or in part, through tinkertech.
Note to self: Find Minerva's supplier. Pretty much any price would be worth it.
Blaster - 12+
Minerva can, armed with obvious weaponry or otherwise, create variously explosive projectiles. These projectiles can be balls of light or created in multiple shapes and can be imbued with the ability to act in a manner believed to be similar to being imbued with Flechette's power, only more effective. No effective limit has been noted in the number of projectiles that Minerva can create.
By "no effective limit" they mean "she's made thousands of the things without looking like she noticed".
The projectiles created seem to be able to home in on targets and be controlled more directly for tactical reasons. It is unknown if these are two distinct abilities or if Minerva is merely controlling the projectiles.
Don't assume you can dodge them.
In addition, when armed with her halberd, Minerva can also fire physical projectiles that act as though they've been imbued with a more effective version of Flechette's power.
Oddly enough, these ones you can dodge, if Leviathan and Ziz are anything to go by.
Suspicion is that Minerva can also generate beam attacks, though so far she has not been observed doing so.
...fuck, the 18 fuckoff-looking beams trick might be something she can do too?
Brute - 9+
Minerva has taken a nuclear explosion at close range and barely noticed beyond needing to adjust her course after she was pushed off. Leviathan was unable to harm her with water pressure, but she isn't fully immune to the laws of physics.
Leviathan was also unable to harm her with that nuke, for that matter. This rating is probably far too low.
Assume physical attacks are useless against her.
In fact, assume they only make her angry, because she sent Leviathan running after that nuke...
Master - 5+
Minerva can create simple drones out of nothing and appears to have access to more obviously constructed drones of various kinds. All of these appear to be under her direct or indirect command. At least one category of these drones is capable of duplicating her Blaster abilities and has blades that can manifest different effects; assume they can do everything listed under Striker.
What, no mention that they all fly too?
It is believed that all of Minerva's drones may be capable of cloaking, but this cannot be confirmed as the primary evidence is video that may have merely had a redaction filter applied to it.
An army of invisible drones that were able to hold their own against Endbringers, you say?
Fucking hell.
The individual known as 'Lilia' is also currently believed to be an artificially intelligent drone programmed to aid and obey Minerva. Likely one of limited usefulness in large-scale combat, given the lack of appearances when Minerva was confronting Endbringers.
The pint-sized pink version of Minerva probably isn't human, but since we've seen her otherwise do a lot of things that Minerva can do anyway? Don't tell her that to her face, at least.
Mover - 8+
Minerva can fly at high speed, has short-range combat teleportation abilities, and has long-range non-combat teleportation available. The latter may be dependent on external devices, based on preferences for certain fixed locations that may be pre-calculated endpoints.
She can dodge better than you can.
Oh, and the feds claimed that the experience was unusually pleasant when they were teleported into Calvert's little dream house bunker.
Current assumption is that it is not actually possible to contain Minerva against her will.
Why would you want to? That might make her angry.
Shaker - 12+
Minerva has shown herself capable of controlling a very wide area around her with traps, force fields, and other effects. This includes force fields capable of containing an Endbringer and traps that are capable of binding an Endbringer in place.
We can't hold her, but she can hold us. Got it.
In addition, Minerva can make items appear and vanish in her general vicinity and seems to use this for, among other things, storing money and other possessions. Included in that are her weapons, so she should never be considered to be unarmed.
...right, assume that she's got an armory with her at all times.
...and possibly an entire field kitchen, because why not?
Striker - 5+
When armed with her halberd, Minerva has access to on-contact effects projected from the weapon. These effects are potentially instantly fatal to parahumans and non-parahumans alike, able to easily pierce the flesh of an Endbringer.
And by "pierce" this means "obliterate". Do not let that thing touch you when it's glowing or fuzzy!
Thinker - 7+
Minerva has the ability to remotely monitor areas through the use of 'sensor drones' and can likely use the sensors of any drone she has active. It is possible that she also has the ability to monitor her surroundings without drones available, but this cannot be proven.
But assume that she has eyes in the back of her head, possibly literally. She dodges things she couldn't possibly have seen coming.
No issues have been observed with monitoring and controlling hundreds of drones, implying an ability to multitask far beyond human norms.
You can't distract her with stupid tricks because she can pay better attention to the surroundings than you can.
Tinker - 0
Minerva does not appear to be a Tinker, but uses Tinkertech and her other abilities may be the product of implanted Tinkertech.
Damned good tinkertech at that, if that's what it is. Where can we get some of that?
Trump - 5+
Minerva has indicated a desire to work on alternate abilities and has shown newly developed abilities after running into problems that she couldn't solve previously.
If you get the better of her, next time she'll be ready for you. Just ask Leviathan...
In addition, Minerva negatively affects Thinkers, especially Precogs, and has abilities demonstrated to be able to disable parahuman abilities in a limited fashion.
She's probably just too awesome to comprehend.
Overall Rating: SSS+
Minerva engaged in combat with and destroyed two Endbringers at the same time without taking any injuries and without any known collateral damage. All suspected means of causing her injury will likely create massive issues for her surroundings without impacting her at all, and it's entirely likely that retaliation on her part would be able to devastate entire regions.
Do not engage and, if at all possible, do not make her angry. Ever.
Special: Diplomacy
It is possible that Minerva is a citizen of an alternate dimension and/or the technical owner and ruler of one or more other planets under the interpretations of several treaties. To this end, she may technically enjoy Diplomatic Immunity to a limited degree, above and beyond the gratitude shown by the majority of the nations of Earth Bet for the destruction of two active Endbringers.
...hopefully she's a friendly foreign power and not taking out Endbringers because they're in the way of conquest.
When possible, approach her as though she is a friendly foreign head of state.
Do not approach her at all if you can avoid it, because to do so is very far above your paygrade.
"Accidentally declared war on Uganda" above your paygrade.
And I don't think we'd win this one.
