What region has the most diverse types in their gyms and E4/Champ?

Question

For example, Steven has a Skarmory, so that would cover both flying AND steel. Are there any regions that have all the types in the gyms and E4? Thanks so much!

Comments

Probably Sinnoh, as the E4 uses lots of dual types and Pokémon that aren’t their type (Flint’s lopunny, for example) and Cynthia has 5 dual typed Pokémon with different types, as well as another that covers another type.

What generation are you looking for? For example, for Johto, would we be looking at GSC teams or HGSS teams?

---

If the region has more than one gaming set(Kanto, Johto, Hoenn, and, not sure if the gyms are different or not, but Unova with B2W2)

---

If possible, could you include the Pokemon you face in the Trials, as well as Grand Trial Battles and the E4 for SMUSUM? Thanks so much!

Answer 1

Most regions' gyms, Elite 4, and champion use every type, so I'll list only the ones that don't.
Kanto (RB): missing bug
Hoenn (RSORAS): missing poison
Hoenn (E): missing bug
Kalos: missing ground and dark
Alola (SM): missing psychic
Galar (Sw): missing electric and ice
Galar (Sh): missing electric
