The Northern Barbarians (北部の蛮族 Hokubu no Banzoku) is a tribe of over three thousand men from the north of Britannia who were easily defeated by Gilthunder and Howzer when they invaded the Kingdom of Liones.
As the Northern Barbarians invaded Liones, they annihilated the knights, who were stationed nearby and fought back, leading one knight to speculate whether the predicted Holy War had begun. The chief of the barbarians, assuming all the knights of the kingdom to be equal in strength to the knights he had fought, leads and orders his subordinates to plunder the kingdom. However, they are then stopped by Gilthunder and Howzer, who arrive on a flying dragon, and easily destroyed the entire army.
- The term "barbarian" refers to a person who is perceived to be uncivilized. The word is often used either in a general reference to member of a nation or ethnos, typically a tribal society as seen by an urban civilization either viewed as inferior, or admired as a noble savage.
