If I release Tapu Koko and beat the Elite Four again, will it respawn?

Question

I know if you KO a Tapu they will respawn if you beat the Elite Four again, but what if I've already caught it and release it? The reason is because I want to catch Tapu Koko in an Ultra ball.

Answer 1

All Pokemon that can respawn will stop respawning when it is caught. Therefore, since you caught Tapu Koko, it will not respawn.

Hope I helped. :)
