dtgreene: Enjoy. It's one of my favorite games in the series, and the SFC version is actually better balanced than the remake. (Well, assuming you don't recruit a High djinks (Lamp Demon), but that's *very* unlikely to happen by accident, and can't happen until post- game.)
(Also, note that the game is in Japanese; if your cartridge is in some other language, it's a bootleg.)
(This reminds me: I still need to attempt Romaning SaGa 2 SFC in Japanese.)
_Auster_: It is indeed in Japanese. I refer to all versions of the console as
SNES "<.<
Also, I don't know much of Japanese, but the dialogues in the game seem fairly simple, even for me. They even avoid using kanji in some parts of the game, probably where players would spend the most time in (e.g. the menu you open with the A button).
And I'm trying to avoid walkthroughs for the games I'm playing, at least in the first time around, so yeah, I'll most likely not find that character you're talking about.
The character I mention is a recruitable monster. Thing is, in DQ6 SFC, you can recruit monsters similar to the way you can recruit them in DQ5. (For whatever reason, they took this out of the remake.) This particular monster is one that you're probably not going to recruit by accident, and you can't get it until post-game, but it's strong enough to break the game if you do get it. (Even if you meet the criteria to recruit one, the chance is only 1/256 for this first one, and 0 for the second and third. Also, I note that the criteria requires using a certain weaker class after you've mastered it, and most players will want to start leveling up a different class with that character instead.)
Edit: To put it another way, if you play the postgame dungeon, you're going to see that character as a normal enemy, but you're probably not going to recruit one.
