>>36113305>implying XY 02 and SM02 are accurate examples of Ash later on in their individual seriesAt the start of XY Ash was still drawn similar to his BW self including how he spoke, at the end of XY he was drawn more mature and spoke more confidently as his design slimmed and proportions changed a little.
It's the same with SM, that Ash looks and acts nothing like how the current SM Ash looks/acts, it's an inaccurate representation of their final self at the ends of each series. This would be a better representation of the M21 Ash since it came from a trailer and not a cherrypicked screenshot of actual footage of the film.
