  The task of extracting and analyzing character networks from works of
fiction, such as novels and movies, has been the object of a number of recent
publications. However, only a very few of them focus on graphic novels, and
even fewer on European graphic novels. In this article, we focus on Thorgal, a
bande dessin{\'e}e, i.e. a comic of the French-Belgian tradition. We manually
annotate all the volumes of this series, in order to constitute a corpus
allowing us to extract its character network. We perform a descriptive analysis
of the network structure and compare it to real-world and fictional social
networks. We also study the effect of character filtering over the network
structure. Finally, we leverage complex network analysis tools to answer two
research questions from the literature, related to the similarity between
Thorgal and the Saga of Icelanders; and to the position of women in the series.
Our data and source code are both publicly available online.
