Since you asked, Virginia,
Quote
"FanFiction: After 20 years, my superhero can still beat up your superhero, but he's chooses to be better than that."
Change "he's" to "he."

Quote
"I prefer Chocolate to Rocky Road. Ask me why?"
The question mark should be a period, since you are instructing someone to ask you a question, you are not asking a question yourself. Alternately, the second sentence could be:

Ask me, "Why?"

But I think that is a lot more awkward.

Quote
"Evil Writer: I love to torture my favorite characters"
and

Quote
"Evil Reader: I love it when a writer tortures my favorite characters"
These both need periods at the end. There are actually several other items that also need periods, but I won't quote them individually here.

Quote
"The Hottest Team in Town! A woman in need of a hero and a man with glasses."
Should the exclamation point be a colon?

How about one more quote?

The math of superheroes: 1 + 1 = 1
