Vargs are werewolves, essentially. They have no prominent presence in any game, and they are very easy to overlook. The only two characters who are vargs are the bit parts of Kelga Vlondett from FF5 and Lone Wolf from FF6.
Kelga Vlondett and Lone Wolf
Viera (TA/12)
A completely female tribe of bunny-ladies (no, I don't know how baby Vieras are made). They're fast on their feet and have great accuracy. Their jobs include Archer, Assassin, Elementalist, Fencer, Red Mage, Sniper, Summoner, and White Mage.
In FF12, the viera have their own village, Eruyt, nestled deep in the Golmore Jungle. They have a communion with the forest, and are fiercely insular. Despite this, there are quite a few viera (like Fran) who have left the forest and are wandering the world. They have very long life-spans and every viera in the game appears young. They have bushy white hair, almost a mane, and have a predilection for revealing clothing.
CP: Viera are reclusive by
nature, living separate from the world outside, shunning even the society of their own kind,
save when necessity demands. This isolation is in part made possible by the viera ability to
hear the spirit voice of the Wood, and thereby know all that comes to pass within Her borders.
Throughout the history of Ivalice, rarely have the viera ventured beyond the borders of the
Wood, and few outsiders know of their laws or customs. [...] Compared to other races, the viera seem to move at a slower, more contemplative pace, more at peace with the flow of time. However, some younger viera have begun to question the wisdom of rejecting change in the midst of a rapidly developing Ivalice.
Yukes (CC)
The Yukes are primarily concentrated in Shella. They are the most proficient in magic, and were the only tribe able to resist the Lilties in ages past. They are the tallest, and most strangely clothed of all the tribes. It is guessed that the Yukes perhaps sacrificed their bodies to increase their magical powers. They are often calm and wise. They appear often quite tall, wear ornate helmets, have small wings, and wear bizarre clashing clothes.
