Falthan is distinguishable from his brother in that he wears his hair loose. He also has a lumi-glow piercing in his right eyebrow. He wears loose clothing in blues and purples.

Falthan, however, is a little more "loosened up" than Vanien is. He's far from being a social butterfly, but he gets along well in a crowd and likes taking a handful of friends to the holo-movies or VR arcade (his treat, of course). He's street-wise to his twin's book-wise, clever if not as intellectual as Vanien is. In addition, while both boys are honest and never lie, Falthan's learned the trick of avoiding the truth, while Vanien would never do so. Despite their differences, though, the two are best of friends, and each is always ready to cover the other's back.
