Thinking about it, I have a hypothesis of what determined whether Anna would have ended up the Shy Girl ir the Monster: in tge Shy Girl timeline, the Antagonists would have decided to go for a containment strategy. In this timeline, they went for extermination.
Basically, in the Shy Girl timeline, they decided to spend a small but steady stream of their units at her, keep the town and Anna from wandering. This would mean a constant drain, true, but it's low-risk and allows them to use the rest of their stuff on other things, which considering the Great Battle was happening was important.
In contrast, in this timeline, they likely decided to redirect more and higher level units to wipe the town out. This would have had a high chance of them removing the resource drain, at the cost more resources in the short-term and a risk of things going wrong. Which it did for them.
...This doesn't
quite fit with my mental image of how Anna-Sekhmet encounter occurs. We can probably assume that on the UN-Antagonists front things
should remain largerly the same, with Sekhmet using its energy mortar superweapon to wipe out the UN fleet, then returning to the Breach for resupply and repair. So that is a fixed sequence of events.
In Monster Anna timeline, this leads to Sekhmet and Monster Anna running into each other, Monster Anna Wave Force-ing Sekhmet in zero range, returning (briefly) to her Arcology to learn of the uprising she had to put down violently, launching herself off to Saskatoon Breach to Wave Force it into oblivion from the inside, then returning to her Arcology to learn it got
completely destroyed while she was making a Breach disappear (and at the distances/velocities involved she couldn't have been gone long), then finally getting into contact with Valkyries investigating the Wave Force effects and fainting right afterwards.
Now, if we assume that Shy Anna was contained to keep her from wandering... Why would she be wandering enough to run into Sekhmet?
There is one battlefield where I feel Summit has an edge. Not against others, but only vs her counterpart.
Summit (blushing): "Hey, uh, Koujirou. I like your hair, it is cute and fluffy."
Coroner: "!!!"
It's like Misaka vs Misaka 11032 if the clone was much shorter.
Otherwise I doubt Summit can handle much about the common AGs for this setting. A Type blocking her evasive teleports would be a disaster. OTOH, there's a chance she can absorb a core and start cross applying her skills. Not a good chance because I suspect Valk Cores count as alive, but it's there.
And Summit can comment that Magical Girl 'shadow' powersets happen all the damn time where she's from, she hoped she was an outlier.
Snerk. Actually yeah, Summit
does have a bolder personality, she actually flirts with handsome Majors of Team GEAR that catch her fancy... Flirts
really badly as in blurts her attraction aloud, but that's still more than Anna has ever accomplished.
Depending on how discovery interacts with EW type AG's, and if she could level up a bit in controlled circumstances, start acquiring some more esoteric effects, Summit could be a complete OCP (as in: the kind of problem civilisations (antagonists in this case) encounter like a sentence encounter a full stop). Particularly if she can manufacture magic items that can be integrated and improved upon by Valks.
Coroner dropped into the Long War would, ultimately, not be an OCP...
Well, possibly if she went full on Arcology mode and started throwing cornucopia machines everywhere.
Can confirm - Summit's
Peerless Explorer and
Instant Manufacture make her a a decent artificer, of anything she examined or fused. This includes erzatz Bolos, hovertanks, magic forcefield generators, power armors, and probably
a lot more than that. The question becomes - whether Valkyrie Core is capable of integration and improvement of fused magical items.
Living things die when put in storage.
Higgs Generators break when put in storage.
Are Valkyrie Cores a system for continual improvement via machinery? And Antagonists part of a system for continual improvement via life?
Not a bad idea... And since Higgs Generators are a really rare commodity,
not testing them at all, like giving it to a Closed Space specialist to test their workability, would be the go-to decision for STRATNET.
Actually... IIRC it's been said that Soul, Magic and Physics in CWMGQ are
very finicky when used in the same project, to break the limitations of one through the other. It's been said that perpetual motion devices (and/or perpetual energy generators) can be built, however they are unreliable in that
one and the same generator will need a dozen or two attempts to switch it on, to actually work as advertised. And if it's ever shut down, it may not work on the next two dozen activations before suddenly working again on its 25th consecutive reactivation attempt.
Frankly, considering how Higgs Generators behave as physics-breaking objects and how they are so finicky, in a crossover I would most likely conflate their behavior with the abovementioned result and call them another hybrid device that taps, in some manner, into non-Physics interactions to produce the results it does... And so requires a lengthy string of reactivation attempts after being shut down (or put in Closed Space storage as the case may be)
