Lost Number caused problems for me my first time at least, because I had never fought him and hadn't read anything about it.. so I ended up with his physical form and I don't think I I survived it (he can after all, one-hit kill all your party members if you're not in the back row and/or have barrier active). Since then I always make sure to get his magical form, and finish him with limits. But yeah, if you fight him as soon as possible, and you don't know anything about the fight before-hand, he may very well be trouble.

Ah yes, Rapps. I know that Aero3 whopped me nicely the first time through, but I can honestly not remember ever losing that fight. I tend to level quite a bit though.
