About This File
Shedinja is normally forced into a standard pokeball in gen 4, however, if you trade a Nincada with a pokeball that is considered "out of bounds" to a sinnoh based game and evolve it there, it will retain the pokeball without forcing it into a standard pokeball. This is one of the few ways to obtain Shedinja outside of a normal pokeball but the sport ball is the only one that meets these prerequisites as Nincada can only be obtained in the bug-catching show on Thursdays and Saturdays.
This particular Shedinja was cute charmed as a Nincada and has been leveled up and EV trained. I've included the original gen 4 file and a gen 8 transferred version of it with a valid home tracker.
