I found a paperback at a thrift store called “How Sluggo Survives” from the “Nancy” comic strip.
Sluggo appears about ten years old, yet he seems to live alone in a shack, he sleeps on bedsprings, his roof leaks, the window glass is broken, he looks like he’s homeless.
I know through the years the strip was drawn by various people, the book has a date of 1989. So anyway, does Sluggo have parents?
Hell, my dad ran away from home when he was 14 and wound up working with a truck driver who drank heavily when he was on the road. Nobody came looking for him and nobody cared.
Apparently, if you weren’t an adorable curly-haired moppet, weren’t wanted by your own family, and were old enough to work and support yourself, social services weren’t about to help you during the Great Depression.
I assume that’s a joke, but it does give me an excuse to mention my frustration with this sort of thing. The current runner is the one who decides canon. In an ongoing work, the purpose of canon is just to maintain some sort of consistent world. It allows the future to be predicted to an extent. That it why the so-called “Word of God” is so important, despite concepts such as “Death of the Author.”
So, no, you can’t say something isn’t canon just because you don’t like the new direction being taken by an ongoing work–not unless you are the current author.
That said, I do wonder if his orphan status is new, since the OP is talking about a 1985 comic. His orphan status could be a retcon, or his parent(s) could have died between then and now.
