Morality Pet: Serves as one for Cray, in the beginning. One suspects that the only reason the party got to six members at all is because Nina kept telling Cray to give them a chance. Cray outgrows the need for one eventually.
Narrator: Each chapter ends with a short narration from her.
It's Personal: With Yuna, after he finds out what he did to Elina.
Jerk with a Heart of Gold: In the beginning, he's really something of a bully. He all but forcibly conscripts Ryu into the party because of his prophetic dreams leading to Elina, and when they don't pan out, considers ditching him. He also beats up Marlok's bodyguard, forces his way into his house, and demands that he give information about Elina while offering nothing in return. His behavior toward the other members of the party, especially Ursula, isn't that great either, and he often ignores their needs entirely unless Nina speaks up for them. And that's not going into his illegal entry into The Empire, which caused a lot of people a lot of problems which he never apologized for. Despite all this, he really does care for Nina and is protective of both her and the party in his own way. And, through the wonders of Character Development (and a few rounds of Break the Cutie) he pretty much drops the "jerk" part completely by the end.
Love Redeems: Cray has his own experience with this when he must ultimately euthanise Elina with the Dragonslayer.
Morality Pet: Nina, in the beginning. One suspects that the only reason the party got to six members at all is because Nina kept telling Cray to give them a chance. He outgrows the need for one eventually.
Nice Job Breaking It, Hero: Finding Cray and Co. illegally across borders, assaulting Imperial soldiers nearly broke the ceasefire The Empire had with the Western Alliance, and by manufacturing a copy of the weapon that Cray also stole (and gave away to Nina, who gave it to Ryu, who broke it,), The Empire was able to modify the treaty between the countries so that they could seize more land on the border, so that they could more easily search for Ryu. A great deal of trouble the True Companions face in the later Acts could have been avoided entirely if Cray had been capable of any degree of subtlety - though he IS right in that Elnia couldn't be found through proper channels, given what the Empire had done to her.
What the Hell, Hero?: He faced a LOT of chewing out from the Ludian court for his illegal entry into The Empire and his loss of a priceless heirloom and symbol of the kingdom. His response was to throw it right back.
Ursula and Ershin also bluntly call him on bad leadership decisions.
Jerk Ass: Deis was hardly warm to Ershin when it was revealed that it had a mind of its own. She absolutely refused to go back inside, cruelly insisting it was never alive and that it should "go back to being a suit of armor," and then leaving it alone in Chek. She eventually realized how selfish this attitude was when Ershin gave up it's life to protect the Abbess, and goes back into the armor to rejoin Ryu.
Took a Level in Badass: Becomes much more useful after an event which occurs about halfway through the game; specifically, unsealing Deis' power allows Ershin to learn a greater variety of skills, including all four level three elemental spells.
Team Pet: Though a surprisingly powerful one once she is leveled up.
Drunken Master: Scias' original characterization in the Japanese version had him constantly falling-down plastered, and still pulling off all the fancpanciest of moves he does in battle. Imagine what he could accomplish sober.
Dummied Out: Scias naturally-gained "Analyse" spell was removed from the english version. It can still be assigned to any character with a Game Shark, though in a buggy state.
Crutch Character: You only control him during his segments of the story, and he's all you'll need. Fou-Lu starts off with a very powerful dragon form, and is at such a high level that despite soloing battles he isn't likely to gain any levels, nor does he even need to.
Do Not Taunt Cthulhu: The Empire doesn't want him around and makes repeated attempts to kill him, which in the end drives his mad and causes him to burn the empire's capital to the ground, in addition to of course, killing nearly everyone sent after.
Driven to Villainy: At first a fairly decent warrior god, but then The Empire that he built keeps trying to kill him after he awakes, putting him through some traumatic experiences, to say the least.
Heel-Face Turn: In the manga ending and arguably in the Good End of the game. He was well on his way there anyway, but then someone thought it'd be a good idea to kill his Morality Pet.
Spared by the Adaptation: In the manga ending, Fou-lu is shown to be alive in the manga adaptation and lives with Ryu travelling the world. The manga ends with the two heading towards Wyndia, Fou-lu wishing to learn what Ryu sees in humanity.
I Know Your True Name: Fou-lu ends up a victim of this...twice over. Once during the botched summoning that called him to the world (and split him in half), the other via Yohm having a bit too much knowledge re name magic.
In the Comic Blade Avarus manga the last page of Chapter 19 has another example (which, of note, occurs right after the manga's depiction of the above scene). Fou-lu is holding Mami's bells, begging Ryu to hurry up and come, whilst giving a postively feral smile. And this is after being run through with the Dragonslayer.
The manga (in its Take a Third Option Ending) starts with Fou-lu going into his "The Reason Humans Suck Speech", and Ryu agreeing and choosing to go with what appears to be the Bad End. He gets better, though.
Fan Nickname: "FUCKING YUNA!" seems to be turning into one on this very wiki.
Karma Houdini: Probably one of the most notable examples of this in video games, especially since he pulls it off twice.He's directly responsible for nearly every bad thing that happens in the game, and to get the best ending, you have to let him get away with it.
To make it even worse, the epilogue makes it very clear that he's already planning to rebuild his operation and do it all again.
Love Hurts: It will if he has anything to say about it. Suffice it to say, Yuna is the last person you want to introduce your significant other to.
Mad Scientist: He has actually been described as Breath of Fire's answer to Hojo, which pretty much hits the nail on the head. To some, Yuna is even more detestable due to being a Karma Houdini.
Meaningful Name: Yuna translates to "night", which is a nice reflection on the type of person he is.
Stupid Sexy Flanders: While he doesn't exactly look bad in the original game, the manga plays up his appearance and makes him more handsome. Justified since young women are a target audience of the publisher.
I Know Your True Name: Yohm engages in this in a very literal sense with Fou-lu—even explicitly commenting to him that the very act of speaking Fou-lu's name sends ripples in the world to such an extent Yohm can be inevitably led to wherever he is. Yes, name magic can be used as essentially radar to find Endless, for values of sufficiently powerful Endless.
Sissy Villain (bordering Camp Gay): Rasso speaks in a very effeminate way in Japanese (to the point it can be described as the Japanese equivalent of Camp Gay) and also has rather effeminate mannerisms. In the 4-komas included in the manga Ryu even refers to him as "okama"—which was translated to "THE GIRLY MAN" in the Fan Translation.
Shout-Out Theme Naming: Rasso's three robots are named "Joh", "Ymechaf" and "Ight". Put together, they form "Joy Mecha Fight", a NES fighting game.
The Unfought: Even though you fight his summons, you never get to battle him directly. The closest one gets is burnination by Kaiser Dragon, and that's not exactly controllable. Still very satisfying to see him annihilated by Kaiser though.
