Is johnny hero the real name?

There isn't enough information to answer your question definitively.

To help me figure out what you're asking, please provide more context:

* Who is "Johnny Hero" referring to? Is this a character from a book, movie, game, or something else?

* What kind of information are you looking for? Do you want to know if "Johnny Hero" is a common name, if it's a fictional name, or something else entirely?

Once you provide more context, I can better understand your question and give you a more helpful answer.
