This much needed feature will not be making a return in Pokemon Omega Ruby and Pokemon Alpha Sapphire. Instead trainer customization will remain exclusive to the Kalos region from Pokemon X/Y (wait, what?!) according to the Game Freak director Junichi Masuda. The only customization players can look forward to is with Cosplay Pikachu...
Gamefreak continues with their tradition of "Here's a great feature everyone likes! Let's cut it!" What made Pokemon XY revolutionary was the ability to customize your avatar how you saw fit and while not entirely flawless, it gave players options but Gamefreak has only gone and taken that away from everyone, a feature which was adored by many.
For once you didn't have to be the cliche pale faced trainer in XY or wear generic threads. Let's not forget how social the franchise has become, which ties in with standing out and looking different. So with GF's backward stance, diversity is thrown out the window.
Ultimately trainer customization is an important feature which gave Gamefreak and Nintendo huge brownie points but with it's exclusion in Omega Ruby/Alpha Sapphire, they seriously dropped the ball. They dropped it.Why would you take a step backwards Gamefreak? Hopefully this awesome feature will make it's triumph return in future Pokemon games outside of remakes, (if that's the problem.) Gen 7 anyone?
