Yeah, and that would lead to an inner conflict Wave would have to face. Instead of, you know, just going "Oh, they are bad so whatever" and doing a 180.

If you want a story with Ran in the lead, wait until I finish my fanfic. Yes, I do think he is a potentially deep and interesting character but he isn't your typical Shounen protagonist, and definitely not a good role model for teenagers (Shounen target audience). He'd fit in a dramatic mystery plot (seeing how he did investigations and all), but he lacks the "cool" factor which makes Wave so likable to fans (last I checked, he was pretty popular).

Seriously, I love Ran. I really do. But the only way to make a story about him interesting (in-universe) is to set it in his past, as that would be where most of his character development happened. And how would a story about him end, if he were the MC? Would he be redeemed in some way? With Wave, I can easily come up with an alternate plot that would follow the Shounen model, have a proper moral etc. and still be AgK-ish. With Ran, I can come up with a lot of things but they wouldn't be in the same vein anymore.
