After finding the Pierino comics, I searched for other (human) comic characters as I haven't found a good list. Most are little boys, most famous probably Dennis the Menace (pic 1, usually wearing red bibs, sometimes blue). The character is 5 1/2 yo but older in the series and movies. Many comics also released as movies or vice versa. I have some entries but still have to add them. I also have to check mangas and animated movies. Pic below from left: Tits, Big Boy, Timmy, Beanie the Meanie, Pat the Brat, Beany and Cecil, Our Gang, Treasure Chest of Fun and Fact.
