Every character in FFIX had a pretty clear job class, but Amarant's was a little hazy. He had some characteristics of a Monk, and some of a Ninja. Let's look at the evidence.
Amarant's weapon is a claw. Although the monk class are known for using their fists, characters like Yang and Sabin have been known to use claws.
He also has very high HP, which is another characteristic of the monk class.
Every single one of Amarant's weapons teaches him 'counter'. This is one of the main abilities of the FFV monk.
However...
Amarant has the ability to throw weapons at the enemy. This is a Ninja ability from past FF's.
He also has rather general 'Flair' abilities. While not actually drawing any parallels with Edge's ninja magic, they do serve a similar sort of purpose, in that they can adapt to many situations.
Amarant's character doesn't really suggest he is a monk. The idea of a 'bounty hunter' is more of a ninja trait than a monk. Monks are known for their discipline, a characteristic which Amarant does not have.
And finally, Amarant is pretty nimble, both in and out of battle. When he first appears in Madain Sari, he jumps from a great height, spends a whole battle dodging around, before leaping upwards again to make his exit. Ninjas are known to be very nimble, in and out of combat.
To be honest, although the evidence is fairly well balanced, I think Amarant's a monk. I was wondering if other people shared this opinion, or whether they thought Amarant was a Ninja. What do you think?
