its boko in 5 boco in tactics, anyways, my oppinion on wiegraf and boco, he had a zodiac stone, why on earth would he need that chocobo anymore? and because he IS useless and its just a re-accuring thing, like Cid, only in FFT hes T.G. Cid, one could make the same argument as with boko/boco so just let it go, maybe they changed a few things so completely sleightly.
