When creating these characters, the authors made a point of illustrating the horrors of life as a Roman conscript. Even if their roles are minor, they bear witness to the terror inspired by our indomitable heroes on a daily basis. For example, instead of celebrating his victory the one time Asterix is just begging to surrender, Caius Flebitus calls the whole camp to his rescue.
It must be said that our little Gaul, who takes on Romans four at a time (and even then he has an unfair advantage!), is seriously starting to get on their nerves.
