It seems that the village chief gives the warriors of the desert their second name at the time when they leave for their journey.
One like Karumerita who has excellent physical strength, gets a name like "Mighty Strength" or "Bone Crusher", those who have good eyes like Baribadomu get names like "Hawk-Eyes" or "Eagle-Eyes".
It seems to be based on their state, in order to understand what their strong points are supposedly.
Just, because of that method of deciding, it seems they've suffered unexpectedly.
Supposedly there are people who can do nothing but boast of their physical strength.
