Amarant Coral is the last character to join the party. His name in the Japanese version of the game is Salamander Coral, a possible reference to the mythological fire creature Salamander as he is known as "The Flaming Amarant" ("The Flaming Salamander"). In the game Amarant has also been called "Red" and in his introductory battle he's identified as "Scarlet Hair". He fights using various gloves or knuckles, much like the monk character class in other Final Fantasy games, but also possesses the "Throw" command, normally associated with the ninja class. His mind is filled with rules of fighting, the biggest of them being "The Victorious Live, and the Defeated Die". Amarant's combative nature and arrogant attitude often leads to conflict, but eventually his personality begins to change under Zidane's influence.
Amarant lives by a harsh code often compared to bushido, where "only the strong survive". Very little is revealed regarding Amarant's extended past; even he can only recall that his first real memory "is of the face of a guy I had to fight. I only found meaning in life through combat." The warrior he wanted to challenge was Zidane but he never got the chance to face him until he met him in Madain Sari, while tracking down Garnet alongside a bounty hunter named Lani, who seems to have a crush on him that Amarant himself seems unaware of. Amarant loses the battle and wishes to die like the honorable fighter he is, but Zidane refuses.
Amarant's reputation as a fighter made him feared in Treno, so King, the owner of one of Treno's waterfront mansions and auction house, hired Amarant as a security guard. When the thief Zidane raids the mansion, he frames Amarant, who becomes a wanted man with a considerable bounty on his head. Afterwards, Amarant works as a mercenary for hire. He's summoned by Queen Brahne to retrieve Princess Garnet's pendant and assassinate Vivi, and he takes the job after learning that Zidane is traveling with the two. Another bounty hunter, Lani, arrives first and holds Eiko hostage, demanding that the princess relinquish the pendant. Compelled by a sense of fairness, Amarant drops in on the pair and saves Eiko. He challenges Lani, who gives up the pendant and retreats. He then turns to duel with Zidane. After losing the fight, Amarant returns the pendant and demands that Zidane deliver the finishing blow. Zidane refuses, and, confused by the thief's mercy, Amarant decides to follow Zidane in order to understand his power.
While with the party, Amarant remains an aloof and dismissive character. His "lone wolf" persona culminates during the raid on Ipsen's Castle, where Amarant seeks to prove that working alone "beats working in a team any day," and sets off in search of a set of mirrors alone. However, after finding the mirrors Amarant falls and nearly dies; he is quickly saved by Zidane, who had re-entered the castle having already made it out with the party and noticed that Amarant hadn't. Amarant is again confused by Zidane's willingness to help him, and his personality gradually begins to change under Zidane's influence. On Terra, Amarant concludes that "Blind pursuit of power is a meaningless vice."
