Has he shown the ability to death hax inanimate matter? Same question to his fear hax.
Crushing Kakine isn't really doing much either, at best that would destroy/incap a single body.
He has been able to kill Statues before via his death abilities, and has shown to able to death hax individual body parts, if that helps. Was also able to kill flame and other elements.
Additionally, considering his aura, Kakine still wouldn't really be able to do anything to Neo, no? Considering his passive aura, and the aura of death he can bring about when he uses his Red Lightning, anything that comes close to him just dies.
Same as the above, I get the "conceptual" part is supposed to make this really impressive, but he still needs feats where he affects inanimate stuff.
See the above. They are the same.
Also, in case this does work, what supports this somehow affecting disconnected bodies?
Not that I recall, no. That said, absorption is an aura, so anything that comes close will get absorbed, and the time stop or devour works by absorbing the time elementals of something, which are like particles that exist in everything, which will erase them from the timeline.
Is it in character for him to erase whole cities as soon as battles start? Kakine can spread himself over a whole island in a second, if the battle keeps going anything less than destroying their half of the planet (or even the whole planet) wouldn't be enough.
Ehhh not really, no, at least not in a normal location such as earth. Though if it reached such an extent that'll require him
The first doesn't cover Kakine's type 8 from what I've seen, even the mechanics behind Kakaine's regen are completely different from the Phoenix and the Minotaur that Neo's profile talks about, I see no reason for his regen to get nulled but even if it does, that doesn't solve Type 8.
Noted.
What exactly would AD and RE do in practice here? His AD seems to amp stats only and I didn’t find anything about RE in his profile whatsoever (not even the category for reactive evolution seems to be there).
It's mostly about his abilities, where if you keep using them more and more, they evolve (in this case, dying or killing himself), and
they evolve based on one's experiences. For example, one of his abilities, Eternal, he got it based on his experience of being in the time stream where he kept aging and deaging, and Eternal skill made him ageless in return. The AD will just keep making him stronger and faster. Though, Neo will eventually reach his third key if the battle keeps continuing, and by then, he'll be able to absorb one's Seed of Existence, which will erase them from a conceptual and informational level, and that does include clones or whatnot iirc.
Anyways, what are Kakine's wincon? For Neo, I'm not sure if he's able to permanently kill Kakine without resorting to instantly EEing the entire world (assume Kakine can cover the entire world within a few seconds, do tell if that's the case) or eventually getting strong enough. That said, I don't see anything that Kakine can do that'll really work on Neo or permanently incap him, especially since he can just come back as pure energy of death.
