The Goths, as depicted in Asterix and the Goths are very strict men (much more than the Romans) showing intrest in military helmets and war drills. They, like the Romans, have big plans for the future however that will eventuly lead to civil war. It all seemed easy: go capture a druid and conquer Rome and Gaul. However that was a big mistake as the indomitable Gauls never give up. Their chief (first Metric than Rhetoric and so on) is very cunnig but even that was no match for Getafix's brain. It appears, from their appearances in later books, that later on the Goths seem to have lost some of their mean attitude.
