There isn't any in Pokemon Fire Red because Hypnosis isn't a TM,now there's your answer.
yes it can
Drowzee and Hypno are top choices. but most psychic Pokemon know/can learn Hypnosis.
you can catch a ralts on route 102 and put an everstone on it, then it will learn hypnosis at level 41
Its not a TM. Your Pokemon has to learn it. like Gastly :) (Gengar in lvl 100 with hypnosis is pwnage :p)
