Is there an "Inevitable Move"?

Question

Is there an move that absolutely nothing can avoid, like Knock Off can't bypass Protect, but Hyper Drill can, but it is a Normal move, so Ghost types can avoid it.

Edit: It was quite finicky to decide what should and shouldn't count, so let's change a bit:

You can submit moves that would never miss under any curcumstances (and when I mean any I mean ANY, except semi-invulnerability, because there is no way around it, because even if you give No Guard to a Hoopa Unbound, there could be a Neutralizing Gas user)

You can also submit scenarios that a move would never miss, also excluding semi-invulnerability if anyone had found a way yet, because there could be one, but it would be a lot of complex setup.

Also, don't limit yourselves to Gen 9, if you found a way in a past Gen, then submit it.

Max Guard blocks every move except G-Max One Blow, G-Max Rapid Flow, and Feint. I think that means G-Max One Blow is the only move that can't be blocked.

---

That is probably true, but Max Guard is not on Gen 9 so maybe there is another

---

S/V has no Max Moves, and all moves that go through protect can be avoided by way of accuracy or immunity.

---

Obs: I'm not counting if the move cannot be used by some reason like Taunt, Torment-Encore, or a Focus item, because that doesn't really use the move, so you would be Just avoiding a move, not that move, y'know what I mean

---

By inevitable, does this only count protection moves or does this factor in all abilities, evasion, Pokemon behind a substitute, Pokemon in a semi-invulnerable state with a move such as Fly or Dig, etc?

---

Also, let's pretend Phamtom Force's semi invulnerable state because there will be no moves that are inevitable

---

Oh I didn't saw Ditto's comment, as I said, couting the semi-invulnerable state of Fly, Dig, Etc... would make all moves avoidable, but then, I wouldn't have a question, so let's pretend they don't exist because no one uses them

Answer 1

As of Generation 9, the move that cannot be blocked whatsoever, regardless of circumstances (except, as Amethyst said, Max Guard), is:

Hyperspace Fury

I am using this list as a reference, but I cut out pretty much all of the moves. Basically, all attacking moves, such as Future Sight, Doom Desire, Feint, either have a type that's immune to it or have 100% accuracy, and that matters because a Pokémon that can boost Evasion can theoretically dodge them. Following that, all status moves are blocked by Good as Gold. As such, Hyperspace Fury is the only move that can land with 100% guarantee in any circumstance.

Additionally, Urshifu using Aerial Ace checks all the boxes: no types are immune to it, and Urshifu's Unseen Fist is able to ignore Protect.

It is worthy to note that the invulnerable turn of moves like Dig and Phantom Force cannot be dodged, with the only exception being Toxic used by a Poison-type, which obviously is blocked by Protect.

Hope this helped!

Just a small correction: Perish Song can be avoided by Soundproof.

oh yea right good shout

---

And also Good as Gold blocks all status moves

---

So the only inevitable move would be Hyperspace Fury

---

ok yea that definitely stops some stuff but imma test if it stops everything

---

Aerial Ace urshifu?

---

yea good shout fish- i mean ditto

---

This is an odd one to add, but Blizzard in Diamond/Pearl only has a chance to bypass Protect/Detect when Hail is up.
Also, if we're accounting for abilities such as Good as Gold, shouldn't Neutralizing Gas be accounted for too?

---

Ditto, I wouldn't be counting Arerial Ace Urshifu, because other Pokémon can use Aerial Ace and they can be blocked in any other case, but in that case, it couldn't be blocked so add Aerial Ace Urshifu in Gen 9.

No for JustATypicalPerson, because it has a CHANCE of bypassing, so if the opposing Pokémon is lucky to be Protected, it would be avoided, so no, and if you count Neutralizing Gas, then you cannot count Aerial Ace Urshifu in Gen 9, and if the Neutralizing Gas wielder faints, then the Pokémon could avoid those moves.

---

Does haze count? I don't think it's possible for haze to miss or fail when used, but it has no effect if no Pokemon has stat changes.

---

Renember: Good as Gold

---

Guys, it just came to my mind, can the terrain moves fail?

---

If said terrain is already up, ig, but their's also taunt

---

Good as gold doesn't block haze.
If we're counting taunt, which technically prevents the move from being used instead of preventing it from succeeding, then we should also count encore which can prevent any move.

---

ykw i think it's pointless trying to say what counts and what doesnt count, so in a bit i'll make a list with different categories ig (those that are blocked by X, those that are blocked by X and Y, etc etc) so ppl can choose which one they reference

---

No, Encore makes the move unusable, not inevitable.
