Another cartoon that is an alternative to the American ones: The Adventures of Tintin by Belgian illustrator Hergé
The Adventures of Tintin is widely regarded as a classic of comic art, but some issues are rightly criticized for racial stereotyping and a romanticized view of colonialism. This is hardly surprising, however, as the series dates back to the 1930s.
While I'm a fan of Tintin (and Asterix, Valerian, and others), I don't think "Hey, this century old European comic is good!" is sending the message that OP thinks it is.
Yes, that's true. Especially in the French-speaking parts of Europe with Hergé, André Franquin, Albert Uderzo, Moebius, Peyo, Edgar P. Jacobs, Pierre Christin, Jean-Claude Mézières and many others.
I might post a few more to this community sometime.
