My sister recently got an apharos at gts from Japan. I checked it out it was shiney, at level 100, and was obtained by "link trade". The "link trade" part seems a little sketchy compared to everything else, what does it mean?
It means the Ampharos has been traded more than once, so it was originally from a trainer in Japan, but would have been traded to others until it reached your sister. That's it ;]
