His AP in this key come from be equal to Shia who fighted and defeated the will of the planet Lutria, also from Hajime himself defeating (without his amps like Limit Break or Overload) the embodiment of all the oceans , the darkness, the wind, vapor and cold of the world simultaneously while holding back so they didn't died and the place in which they were wasn't destroyed. The existence erasure isn't able, that's something possible when bloodlusted, all the rest of the equipment is usable in the last key. The sealing I don't remember from what come, but isn't much in character.
Why does the first thing matter. How does being the will of the planet translate to ap in anyway.
In the case of the pockets realms they were destroyed with their fight and even a character much more weaker than them (Miledi) could compress all of the pocket realms with her final magic, and Lutria is said to be even more powerful than Ehit, while she also have the power of all the divine spirits (the emboidment of the thing they are) together. But if you don't like this feats, thing that I can understand, could be used the feat of stomping hell, a planet with nine layers each of them of various km high, when Hajime was fighting in the last layers the impact make earthquake that were sensed even in the surface.
The comment I make could make you feel better for the AP rating, if possible can be mentioned other feats but I think that can work sufficient.
No problem, come later, I will also be a bit busy because of mother day so sometimes I could also take time to respond.
With Bolas can restrain the target with it quickly wrapping the space, with Orestes he can teleport his attacks and they can also sever the body by shrinking the portal's size, Cross Bits create space isolation barriers (can be of multiple layers) can attack with space magic and self explode, Gran Farensen is a granade of gravity to drag foes towards it, Exise Bullet are bullets than can teleport between them and Hajime also can teleport to them, Space Explosion Grenade that distort space and generate shock waves powerful enough to prevent teleportation, and the Crystal Key that can create a gate to any place. This I think is all the artifacts with space magic, I think he himself can also enchant himself with it to make space magic attacks though I'm not completely sure of this, aside from that Hajime also have other artifacts that do other things so I think would be the better for The Hunter use equipment that are balanced, if a armor is good against electricity, mind manipulation, and poison, but it's weak or not so great against fire (just to say a example) things like Hyperion would be fatal for him.
A base mind resistance is not enough, 'even a non-combatant like Aiko could resist Noint's dark magic which brainwashes her opponents', and the mind manipulation of Hajime work in persons of his level, and even have changed the memory of the whole planet.
How likely is Hajime starting with mind manipulation.
He normally open with his guns, but can easily use the other things if he want. The guns don't gonna hurt The Hunter so he would instantly change to Schalgen AA which focus in pierce power and missiles, Schalgen have immense pierce power and in the few intances in which couldn't pierce something Hajime would shoot it various times in the exact same place to pierce, the effectivity of the missiles would depend in the temperature damage that you mentioned, so not gonna touch that part until a clear answer of the site about that.
Between the "tricks" he do is more common that he use the mind manipulation or soul manipulation, he also use the metal particles relatively often, if I have to say, in a serious fight he use it more often than the mind and soul manipulation.
As I said, Pulse Hyperion equaled the personification of the fire of the world, to begin with they have in their inside little suns, so the heat from them is high, and he can use various at the same time.
Don't know about Bat woman but if that's literally true then wow. In this case mean something because is no a title granted, she is literally that, the will of all the fire in the world, the same way his mother for example is the literal will of the entire planet, they affect the thing they incarnate in the entire planet and the damage to them would affect the entire world.
Ok.
I mentioned two keys because The Hunter for example only have the High 6-A as possibly, if it was a solid High 6-A I would just used the After Story key. And almost all of him come from artifacts, he can't use most of his hax without them, and he have them available literally in any moment. And just to remember, the mind and soul work in persons with resistance to them, high resistance on top of that, and the cities are modern cities wich I think have more population than the cities in the Monster Hunter world.
The mind manipulation of Hajime is above that, just wanted to mention cities because of consider that the modern city I think should have more poblation than cities from Monster Hunter, though as you said it doesn't matter.
Have a safe trip
