Oh man, i absolutely love Memín Pinguín, it's a mexican comic, although it is quite controversial due to the racial stereotypes, but i don't really mind that.
The main protagonist is a black kid who lives in 1930s Mexico City and has a shit ton of adventures with his gang, like, this kid does some interesting stuff, he once went to Africa in an expedition and almost got sacrificed by the natives.
The comic also deals with a ton of problems of the real life, like racism, differences in class (one of the kids is super rich while the rest are poor), alcoholism, prostitution, discrimination, crime (a lot of crime, suprisingly, like this kids found dead people and gangs all the time). It's fun but also quite sad at times. I have like a 100 issues of the comics, they are my treasure because i can't find any more in this day and age.
