The designated main character of a comic strip is not necessarily the one that readers get attached to. If we’d managed to sell the strip and if it had had any kind of run who knows which character would have got the spotlight. With many strips the breakout character is only a minor part of the cast. Sometimes they aren’t even in the original cast. Popeye, Snoopy and Opus were all late blooming stars of their respective strips.
If I’d been the writer I’d have gone with the Crazy Kid as the main protagonist. I have a great fondness for psychotic little girls.
In the beginning at least our protagonist seemed to be the Put Upon Dad. He was the viewpoint character in all the strips I drew.
