Like the previous Pokemon Sun and Moon versions, Pokemon Ultra Sun and Ultra Moon feature community challenges called Global Missions, the first of which recently concluded. Unfortunately, players weren't anywhere close to hitting the target goal.

The first Global Mission in Pokemon Ultra Sun and Ultra Moon was called "Catch a lot of Pokemon," and it tasked players around the world with a straightforward challenge: capture 10 million Pokemon across both titles in 10 days. However, players only managed to catch 5,442,088 Pokemon (via Pokemon fansite Serebii), which is only slightly more than half of the target number.
