All Fanalis have red hair and eyes. Most Fanalis have a piercing under their lower lip.
The true form of a Fanalis is like a strange beast with a skin like steel and its color is a deep crimson red. This transformation happens to a Fanalis after passing the Great Rift and reaching the Fanalis' homeland.
Their physical strength and senses are way above that of a normal human. They can jump to extraordinary heights and even break metal. Their kicks are like lightning and they can even take down the mighty king of beasts in one blow. Fanalis that are "pure bloods" are stronger than those who are not. Due to their great physical strength, they have low quantities of Magoi (because of this, using Metal Vessels or Household Vessels often leave them paralyzed or close to death) but half bloods seem to have more Magoi than pure bloods.
The Fanalis people are based on the real-life Berber people. This is supported by the fact that the Dark Continent which they hail from is based on Africa (specifically North Africa) and that the Fanalis (like the real-life Berbers) were often kidnapped and forced into slavery or forced to become soldiers. Their "wild" nature (or at least their perceived nature by other countries) parallels the Greek and Roman view of Berbers as barbarians.
Every shown Fanalis has had the same fighting stance.
Mostly every known Fanalis has a name that contains a R except Muu Alexius, Lo'lo' and Yaqut.
The tribe name "Fanalis" might be derived from some sort of combination of the Modern Greek word Φανάρι Fanari, meaning "lantern", with the Arabic word فارِس Fāris [fem: فارِسة Fārisa(t)], which has the meanings of "Knight/Horseman/Keen-eyed person/One who kills a prey".
