Well, 'Mr Nobody' in science fiction can often be a symbol. Sometimes it's a character who has no identity in the traditional sense, perhaps due to some scientific experiment gone wrong. For example, he could be a test subject who lost his original identity and now roams the science - fictional world in a state of limbo, causing confusion or being a source of mystery for other characters. He might also be an alien form that is so different from what is known that it's named 'Mr Nobody' as a way to convey its unknowability.
No, it's not that common. While there are various unique and mysterious concepts in science fiction, 'Mr Nobody' isn't as widespread as some other tropes like time travel or alien invasions.
Well, it depends on how you define 'good'. In some story arcs, Mr Nobody shows redeeming qualities and actions that could be considered moving towards the 'good' side. But it's not a straightforward black and white change.
