Small corrections, the standard orbs around her fists work still work with gravity as well as dark energy. They're explicitly stated to be repulsive because they generate a heavy concentration of gravitons, and Dark Graviton: Bomb uses condensed dark energy to do its damage. Furthermore, the repulsive barrier created by the gravitons her body gives off does protect her from energy as well as physical attacks. It's literally the exact same thing as the orbs she forms around her limbs. However, it's also noted in-game that the passive field is much weaker than the consciously generated gravitational fields she makes around her hands and feet.
You are right to call me out on Dark Energy because I threw it halfassedly. I didn't really expect to be pulled in a discussion about Alice's power tbh. Girlfriend is fine and all but her power is fucked up.
This is exactly how I see her powers:
The thing with Alice is that even the info from the game doesn't tells us what we need to know. Gravitons don't repulse, they attract. They aren't even real, they are theoretical particles to plug in holes in our understanding of a certain phenomenon. And even if they are real in this game, Deryl still doesn't know what the hell they do, so he says that it's Gravity or Anti-Gravity or Dark Energy.
Since Deryl mentioned all these, we have a framework that allows Alice to use both Attractive and Repulsive forces. We also know that Alice's powers tend to have spin and pull things into orbit. So let's see all the powers she has manifested:
1. Fist Orbs
We've seen 3 variations of Fist Orbs.
a) The common punching orbs. They only repulse and work in a way that don't cause recoil to Alice. They have never ever pulled a physical obstacle in orbit and when she deflected Klaus' plasma, the effect was similar to an elastic collision, not a bent trajectory. In fact they seem to be dormant up till the moment something touches them.
b) The grounding orbs. She uses them against the monsterfied Aldain. Seemingly she pulls the energy into a stable orbit around her hands, then follows up with her own. We don't exactly know how she interacted with the electric energy aside from that.
c) The attracting orbs. This is a new power she manifested once she evolved. She is capable of targeting something and attracting it towards her fists.
At this point we have to assume that all the variations are mutually exclusive. We don't know how fast she can switch, but it has to add reaction time.
2. Protective Barrier.
This is one of the most inconsistent things about her. MC feels a "zap" when he touches it, but it can't be electricity because he would feel it. So whatever her barrier is, it probably has motion. When MC tries to stab her though, the knife edge gets mangled like it was bombarded by something. It could be air, it could be some field of erratic forces. The certain thing is that it doesn't pull stuff into orbit because the knife didn't glance or bounce, it went right through, but looked like stabbing a bed of rocks.
3. Graviton Impact
She basically smashes her punching orbs together creating a shockwave around her. This is mechanically a sound attack. Alice barely feels recoil and all this energy created by touching her orbs has to go somewhere. So if the orb can't repulse another orb, the energy is dissipated in a shockwave.
4. Dark Graviton: Bomb.
And this is the damn problem with Alice. Gravitons and Dark Energy are dinstict and different things. Their only "connection" is that they are opposites. Alice names her power Dark Graviton, but she explains that she condenses Dark Energy. For all intends and purposes this is your run of the mill explosion. But it also seems that "Dark Gravity" is a concept in the game, or at least Alice believes it's something distinct.
5. True Graviton: Minute Collapsar.
This is the opposite of her Bomb ability. It's an implosion. I wonder why she had to channel so much to produce. Additionally it's name suggests a trend. Dark Gravitons is Dark Energy and True Gravitons is Normal Gravity. It also suggests that Alice will eventually manage to use Graviton Impact on the attracting orbs, not just the repulsive ones. I refuse to believe that these names are random, because WW has written the script in advance.
It doesn't change anything though. You're absolutely correct that Met would still mess her up, even if her powers technically would protect her from him. It's just that it'd be as effective as trying to block a train with a piece of cardboard. If at Level 1 her passive barrier couldn't stop another Level 1 from whooping her ass, I highly doubt that her passive barrier have damn near any effectiveness on a Level 3's attacks.
Yeah, the Klaus argument is my strongest one too. If we had observed her barrier do anything revolving an orbit or a bent trajectory like her fists, I'd say that there would be a possibility that she would be good against electricity. But since it doesn't, I highly doubt that Met will have trouble hitting her.
