Mega Evolution has been incredibly popular among Pokemon fans since it was introduced, with the phenomenon recently inspiring an artist from the Pokemon community to create their own Mega Yveltal design. Though the legendary Pokemon Xerneas and Yveltal strangely didn't get their own official Mega forms when they were introduced in the Gen 6 Pokemon games, fans have shared many of their own custom designs over the years, with the recent reveal of Pokemon Legends: Z-A resulting in tons of new fan-made Mega concepts.
