Superhero

Of course every dad is a superhero in his kids’ eyes. I’m “just fortunate” to have a beagle that looks up to me as well, presumably as some sort of God of Food.
However, if I had to choose a superhero guise other than my own, it would probably be something along the lines of Technically Correct Man:
RescueOr Captain Pedantic.
Or Professor Meticulous.

Hmm. I’ll have to give this further thought – it’s obviously important to get it just right.
