Which Pokemon has only 1 weakness?

Question

This could be an ultimate team on my Ultra Moon file.

I have all Pokémon games to do a LOT of trades, some I have to do a double trade
(example: Transferring Pokemon to Heart Gold and then transfer it to Ultra Moon)*

I need it to take advantage of ALL trainers, even Hau!

*these trades could get messy

Answer 3

Scizor, Drapion, Stuntank, Spiritomb, Sableye, pure normal types, pure electric types, Genesect, pure normal types under the affect of Trick Or Treat, Durant, Water/Ground types, and Escavelier all have only one weakness (pure normal, Bug/Steel, Water/Ground, Normal/Ghost, pure Electric, Dark/Poison, and Dark/Ghost).

Elektross has 0 weakness due to Levitate, so if you're going for the Pokemon with the least weaknesses, it's Elektross.

Hope this helps! :)

Comments

I think u mean under the effect of trick or treat. But even so ghost moves do not affect normal types.

---

Oh yeah, Trick Or Treat.


And im pretty sure Trick Or Treat works on normal types?

---

Normal/Ghost would only be weak to Dark.

Answer 4

Durant has 1 weakness which is fire. However you must trade it from a older game in order to get it on Ultra Moon. Also if you like battling, Durant is one of the most used in the world championships.

Answer 5

Pure Electric and Normal-types have 1 weakness. Spiritomb and Sableye only has a Fairy weakness.
Those are a few examples, though other types like Water and Ghost only have 2 weaknesses.
Elektross has 0 weaknesses because of Levitate.
