Alexander did not expect to find himself caught in one of those space time distortions and sent back in time and it also seems that it was adjusting his form to match. Guess he'll have to figure out what's up on four legs as a Hisuian Samurott!

This pic was done by  Ageaus as part of his Pokemon theming and came out great~ Glad for the details that came with the changing and fitting that we both picked Oshawott
