The common appearance of a German was tall, light hair and eyes, pale skin and among the men, broad shoulders. The German people did not wear much in clothing or armor and were often targets of Roman taunts.
In The ShowEdit
In the show, the Germans are portrayed as being physically imposing, proud, fierce, violent, and aggressive warriors, but also do not trust people in general, including their own kind, despite this, most Germans have a sense of honor, and loyalty, only trust those who have proven themselves trustworthy to them, they are also calm, and level-headed.
The language they speak in the show is a heavily accented version of modern-day German, but quite often even native speakers have trouble understanding the words spoken. The subtitles often do not literally translate the actual words and phrases being spoken.
