Question: what pokemon do you get when you complete a ripple in time?
Answer: GO Celebi! Celebi has finally made an appearance in Pokémon GO, and joins Mew as one of only two Mythical Pokémon in the game to date. Much like Mew, you also unlock Celebi through a lengthy Special Research Quest. It's called A Ripple In Time, and it acts very similarly to A Mythical Discovery.
