It was a Gaffer that gave mine, pretty sure it's a legit RNGed one (cloned of course) from previous gens (got it in my Y copy). It doesn't have the pentagon too.Do be aware that any pentagon 6 IV Ditto are probably hacked. There's only a 1/29791 chance that a 3 star Dex Nav Ditto is 6 IV which is your best chance since you can't breed Ditto for IV and there's no RNGing. 6 IV non-pentagon Ditto should be pretty easy to come by (foreign 6 IV ditto are commonly used for the Masuda method to breed shinies and it was easy to RNG them in previous generations).
