A Pokemon fan combined three of Deoxys's forms to create Mega Deoxys, based on Mega Evolutions. Pokemon introduced Mega Evolutions in the sixth generation, which includes Pokemon X and Pokemon Y. Mega Evolutions allow particular Pokemon to react to a Mega Stone, so they'll transform and become more powerful while also learning new attacks. Since the inception of Mega Evolutions, some fans have created original versions to show their interest in the mechanic.
