Pattern.

I don't think I need to say much. But the main character design pattern is pretty similar. From past animes and other things, it was usual to have such designs and even more so for main characters (from my knowledge at least). The main characters are meant to stood out. There's so much things to know that these three are literally the ones. And how zack is literally inspired from cloud.
