I don’t really have a specific headcanon for that, but I do think it’s interesting that it’s called “Megamind Unmasked” since he doesn’t wear a mask? There’s the disguise watch, of course, but it’s implied to be a fairly new thing, and one that the people of the city don’t seem to know about, as the Warden doesn’t recognize what it is.

So as far as the public knows, Megamind doesn’t wear masks or hide his identity. So why ‘unmasked’? Is it a conspiracy theory book positing that Megamind isn’t really alien? Is it an unauthorized biography claiming to know Megamind’s true motivations, etc.? Wild speculations about him?

And I wonder, too, if it’s a local book–like, self-published, only really available in Metro City’s library?–or if Megamind is famous enough outside of Metro City that people who live elsewhere write books about him.

I don’t think the book would contain a lot of personal information about him, though, at least probably not correct personal information; remember that Megamind tells Roxanne about his childhood when she asks him to talk about something he’s never told anyone else before.
