It was the plan when I initially started working on the game, but somewhere along the way in early development I decided to make him a unique character that can't be changed.
It is a neat idea on surface, but I quickly realized how much work it would be. Like, I'd have to make a gazillion variations of each panel for the comics for example.
And for the player, I wanted him to be more "invisible" in a way. He still needs to appear on screen sometimes so when he is shown, he is portrayed in a very basic way and with a medium ish skin color so hopefully as many people can self insert themselves into the game.
At least that's how I imagined it would be the best for the experience I wanted to make. Hope this was helpful. <3
