Which pokemon lore would you like to see expanded?

For me, it’s Deoxys. I love everything related to outer space, so I think it would be super interesting to know where Deoxys comes from (planet, if any) and what is the virus that helped create them when they were exposed to a laser beam. The laser beam makes me think that perhaps some sort of machinery was involved and that means that some aliens or humans must’ve have provoked it.
