I like how each character represents certain aspects of comics.

Hiro is all about the innocence and fun about being a superhero. He also represents the journey of a hero.

The cheerleader is all about what a teenager faces in high school (obviously) topped off with being "weird".

Peter and his brother represent the secret identities in comics, moreso than the cheerleader.

Not sure about DL, Micah, and Nikki.
