[spoiler=Character Info - Porom's Tale]Child Porom: You play as her in a flashback that makes up about a third/half of the tale. She's pretty much the same as before, except she lacks her Cry command, and Twincast is now a band instead of a command. I didn't try the Twincast band but I imagine it's the same as always.
Child Palom: Same as always, except for the Twincast band mention above.
Adult Porom: Not all that different from herself as a child, she now has Pray, which works like it did in the original, rather than restoring HP and MP like the DS version. There's really not much else to say...she dyed her hair pink; I guess that qualifies.
Rydia, White Mage, Black Mage, Kain: Same as in the other tales. Kain is his dark side.
Elder: The Mysidian Elder, who aspire showed was likely intended to be more playable than he is at one point. You play as him in one battle, where he promptly gets his ass kicked. He knows most of the white magic spells, and seems to use standard mage gear.[/spoiler]
[spoiler=Character Info - Edward's Tale]Edward: Edward is actually a competent fighter now, or his partners are just as bad as him, making him seem good. His Bardsong command works sort of like the original sing, except you can manually choose its target, and it uses healing/defensive spells when targeting allies. I thought that was a really cool change, but I never really bothered with it on enemies since it's just as useless as before. His Salve command is the same as the DS version, you chose the item to split, and it gets used on every character in the party. I'm fairly certain the DS version only used one item though, this subtracts one for each character. It's still a lot more useful than it was in the original. His Hide command was changed to Escape, but does the exact same thing, unless you count being able to see him hiding at the edge of the screen to be a difference.
Guard A, B, C: This is just getting ridiculous... These are three identical soldiers, they use the same portrait as Wedge and Biggs, and equip heavy armor and swords. Worthless, unnamed characters like this are the one thing I do not like about this game. Lower the strength of the enemies so the party can handle them on their own, like the original game. Don't give the player useless "support" that they'll never see again.
Harley: Edward's secretary. A woman with blue hair, she's supposed to be a scholar, but doesn't have any of the traditional scholar abilities. She uses whips instead of beating her enemies to death with books like the scholars in FF3. She has two commands; Piercing Sight, which uses dispels animation and is supposed to work like dispel, plus set a weakness. Not one enemy cast protective magic on themselves, and there is no way of seeing what weakness was set in this tale, so I can't say if it does what it says or not. She also has Gil Toss, which isn't nearly as powerful as it was in FF5, but an NPC says it gets stronger at higher levels.[/spoiler]
[spoiler=Character Info - The Lunarians' Tale]Goblez: Remember the half-naked "man in black" I mentioned way back in Rydia's tale? Yeah, that's Golbez. The character redesign isn't nearly as bad as Luca, but I'm still not a fan of it. Anyway, Golbez is surprisingly proficient at physical violence despite never using a non-magical attack in the original game. He can equip swords and staves, plus heavy armor and mage gear; he starts with an ancient sword as his weapon. There isn't enough equipment in this tale to know for sure, but I wouldn't doubt it if he has the same or a very similar equipment selection as paladin Cecil. He knows black magic as expected, but only purely offensive spells, he didn't learn a single status effecting spell as far as I leveled him. Speaking of levels, he starts at 30, and can go beyond the level 40 cap the other characters had in their tales. He has two unique commands as well: Pressure, which sets paralysis on a single enemy, uses the same animation as binding cold, and has an abysmal success rate. Taunt draws all attacks to him, which is useful for keeping the mop alive, but can't be unset.
Interestingly, you also get to play as Golbez in a few flashback battles to the original game, where he only has access to black magic and physical attacks (using an ebony blade - a weak sword that can be unequipped and used in the present). They drew new, FF6-style battle sprites for him in the flashbacks, unlike every other character that uses their original battle sprites. The FF6 sprite sucks compared to my costume for Cyan:

Fusoya: The mop is still Tellah 2.0, unfortunately; he's capped at 190 MP. He starts at level 30 like Golbez, but still has access to every spell in the game. His Bless command has been upgraded, it restores a small percentage of HP and MP, unlike the original that did a fixed 10 HP, or the DS version that did a percentage of MP. I believe he uses the exact same portrait that he did in FF4 Advance, unlike every other character. He probably died at the end of the tale.[/spoiler]
