I was using the GTS in Pokémon Ultra Moon and got a Scizor. It had max EVs, max level, and had Pokerus. Though I was just expecting a regular one for my shiny Trumbeak. The same thing happened. I was wonder trading until I found out that two other of my Pokemon had Pokerus: Malamar and Meowth. This is strange because they were all just freebees. So, do people not want them, or are they hacked?
