Idealization has always bugged me, to be honest. We make certain people out to be these pure awesome beings, yet they're most likely not so different from us ordinary folk.
Tony Stark(need I say why?)
Bruce Banner/The Hulk
Every good heroe has flaws.
Even since the dawn of time in the first ever told stories the hero-even the immortal ones-all had a fatal flaw that could do them in.
Joking. Awesome stamp, I think a lot of people kind of conveniently forget about any flaws their heroes have, but it's important to remember.
