Wait, so this is being argued like it's not a stomp? Well... *cracks knuckles*
@Assalt. Arceus is the one getting like, the least changes that matter from that thread, so...
@Everyone. If this isn't a stomp, Arceus uses the
move Stomp and performs the lowest of low diffs, regardless of the nature of Demigra's mindhax.
One, Arceus has 3 layers of 4D mind defense: natural resistance, passive barriers, and plates (Demigra would also have to mindhax not just the llama avatar to win, which is a feat in itself, but the entire Original Spirit, which is a Multiverse so big that well...let the link on Arceus's page explain).
Two, Arceus has such an AP advantage that a burp takes out everyone in all of DB, canon or otherwise. And given that Belch is a move (and a powerful one at that), I'm not even kidding. Demigra can't hurt him and even if he could, Arceus has both, passsive and active healing.
Three, possession is taken care of due to Ghost Plate.
Four, Demigra's resistances pale in comparison to Arceus's hax potency, even if Arceus didn't have resistance negation. Time stop, mind hax, etc. all fall to people
below Arceus, like Uxie or Dialga. Heck, if Demigra's mindhax
isn't 4-D, he gets outdone by
Hypno. Freaking Hypno. And when it comes to mindhax/mindhax resistance,
Hypno<
Malamar<<<<<<<<
Mewtwo<<<<<<<<<<<<<<<<<<<<<<<
The Lake Trio (where the 4D mindhax kicks in, btw)<<<
Dialga and
Palkia<
Giratina<<<<<any single one of Arceus's mindhax defenses.
Five, just...Arceus's hax as a whole. Even with the things getting removed, Demigra is outhaxed by any member of the Creation Trio (Except like, Palkia maybe. Don't get any ideas. Palkia still wrecks.), let alone Arceus. Demigra's survivability is useless here. Even if by some hilarious turn of circumstances Arceus can't kill Demigra, Arceus BFRs to the Distortion World or Lost Zone. Speaking of survivability...
Six, Arceus's own survivability. Say Demigra manages to get pst everything I listed, all of Arceus's defenses, all of Arceus's stats, and beats the llama. Congratulations. You took down
one Avatar. There's (insert amount of universes in Pokémon * amount of humans and Pokémon in a single universe) llamas to go.
