[S/M] Can you re battle Tapu Koko?

[Noodles]

Can you rebattle Tapu koko if you kill it the first time when you beat the elite 4?And how.

[Idle]

Im certain you just go to it like the other tapus once you beat the elite four and touch the stone in the ruins to make him appear

[Llocin1151]

I can confirm because I accidently made it faint the first time I fought it. As Idle says, simply defend your title at the Elite Four again and touch the stone at the ruins.

You can still reencounter Tapu Koko at the stone even if you fainted it for the first time. You don't have to battle the elite four again.

I defeated Tapu Koko the first round, and reencountered it after post game.
