I am looking for an animated series I watched when I was little, beginning of the 2000's. I think it was on one of the channels offered by Canal+ (French encrypted television channel).
It was a western-style animated series, in a post-apocalyptic setting. For all the following points, I am not sure if they are true or not, as I was quite young:
- the hero is a badass guy that flies a red plane;
- he is recruited/asked/? by the city of the good people;
- the prince of this city looks very similar as the prince of the city of evil people;
- it is revealed later that they have the same mother, and are half-brothers;
- the king/chief/? of the evil people has orange or yellow eyes.
I am not sure anymore for any of this and every time I ask around, nobody knows about this series.
