What is the max amount of immunities a Pokemon can legally have in battle?

Question

Including typing, abilities, moves, etc.

Comments

Illegally, a Sableye or Spiritomb with Wonder Guard would be immune to everything but Fairy.

---

actually it would be a pure electric with wonder guard and air balloon

---

Or a wonder guard burn up fire type

---

But legally wouldn't it be shedninja?

---

That Shedinja can still get hit by grass attacks.

Answer 1

I'm assuming you want it to be legitimate. If this is the case, a Shedinja under the influence of the move Soak and holding the item Heavy-Duty Boots would be immune to every single entry hazard. It would also be immune to all types but Grass and Electric. It still wouldn't be immune to weather, however. Just watch out for Mold Breaker, that'll ruin everything.

In Gen 9 NatDex formats, Shedinja can hold an Air Balloon and Terastallize into an Electric type, giving it zero conventional weaknesses. This can still be worked around with hazards, weather, status, and other sources of damage such as Rocky Helmet, but Shedinja often makes itself even more unkillable with Substitute support from Shed Tail Cyclizar.

Why would it be immune to Hail?

---

It isn't, I'm saying that's one of the only things it isn't immune to.

---

Oh, oops. I misread it.

---

Hey what about elektross

---

Eelektross has one immunity. Shedinja has far more than that.

---

Elektross only doesn't have weaknesses, but that doesn't mean it has all immunities

Answer 2

I know 2 ways to make a Pokemon immune to every type of attack. Both require wonder guard.
pure electric or poison dark Pokemon that used magnet rise or is holding an air balloon
pure fire Pokemon that used burn up

But I looked it up and it kept saying wonder guard can't be given to another pokemon in any way(entrainment, skill swap, trace and entrainment) is what I read wrong or what?

---

The question wants a legal possibility. As Wonder Guard can't be passed to another Pokemon, these methods aren't legit.

---

Which site says entrainment doesn't work on wonder guard? Bulbapedia says it does.

---

I must've read wrong. Looks like it can be Entrained. My bad, sorry.
