What types do 你 want the gym leaders and the elite four to use in Pokemon Sun/Moon?

Dark
Ground
Fairy
Fire

For the champ...

Dragon 或者 Misc. It don't matter.

One existing type I can think of for Gym Leaders is Dark.

One idea I've had for a new type(whether it's for an E4 member 或者 a gym leader is Space(As in Outer Space).

Dark type gym leader. Dark type is the only type without gym leader.
