>>36494059There's not much else available in Johto
Pidgeot is garbage.
So is Noctowl.
Xatu is okayish but Fly is a terrible STAB on it but he gets Psychic and in gen 4 it gets Signal beam for Dark types.
Skarmory is (Soul) Silver exclusive and while it is a great bulky mon, it's offensively weaker than Crobat
Fearow is...eh, not terrible but it has the same base atk as Crobat while being slower.
Murkrow is bad and in postgame but in HGSS you can find one in the Safari Zone and get a Dusk Stone at the Pokeathlon or get lucky at the Bug Catching Contest.
>Farfetch'dAnd the last one should be Doduo which...is found just before the E4 or in the Safari Zone in HGSS, that being said it has very nice stats.
tl;dr Crobat isn't the worst bird in the Johto games but there's some better stuff if you're willing to wait
