Soaring in Torren - Delta Drifloon

In the first time I used Emolga Taxi, I was with my team of level 70 Pokémon, and Delta Drifloon already had learned explosion, as he was also at level 70 something… Someone can tell me if it respawns, or if I lost it?

Usually non-Grotto Deltas don’t spawn again once defeated. Might want to soft reset if you haven’t saved yet.

he respawns, (sorry for necro-posting)

i need delta drifloon
