Asterix and Obelix, TinTin,
Gaston, a lot from
Willy Vandersteen, Lucky Luke, and a lot I've no idea what they're called in English (or even in Dutch anymore which makes searching difficult). But I do know a lot came from Belgian writers.
I used to go to the library every saturday, and spend about an hour in the comic book corner (shelves full of them, with comfortable couches in front) before picking up the books I wanted to take home.
Now, Suske en Wiske (from Willy Vandersteen, or rather his successor), and Donald Duck (weekly magazine).
