Well hello hello! Background
Simple explanation is, the gifs we are using for the Events Gallery, isn't perfect.
Best example here is Pheromosa:
As Pheromosa back texture is meant to be semi-translucent, as a result, it captured the background.
Task for Volunteers
What is required, is for translucent areas to retain their original tint, while being translucent.
Example of effect (using static Pheromosa):
Species
And here's the rest of the USUM gifs (Blacephalon, Dusk Lycanroc, Poipole, Naganadel, Dusk/Dawn/Ultra Necrozma, Stakataka, Zeraora).
Someone needs to remove the background please. I already cut them to the right size and took care about the loop.
