Mistake?
Originally, Gio's eyes were in shadow, but when the idea struck me, I couldn't help but do this! Wait, I think I made a mistake... That isn't Gio!
For one thing Gio has a Charizard not a Charizard and he has ORANGE eyes not blue!
Right? Nope, that's not a mistake! This is a younger Gio when he had just got his Charmander, age 11. But what changed his eye color?
