Add "dragons practically consider me family!" to the first option with Birds, and that describes my typical transport. XD
I use fly all of the time unless it is the next city over.
This. Otherwise, I'll probably use the Bicycle.
In
Sapphire, Rayquaza and the Fly HM were like best buddies. I used this to travel everywhere; the only time I traveled on foot extensively from town to town was to typically enjoy the scenery.
Right now, a a Fearow in
FireRed and an Articuno in
Emerald are my primary HM-Fly users.
I considered using a Charizard with Fly as my primary "Flyer" until I learned that it is offensively more invested in Special Attack. -.- I'm still waiting for the day when Rayquaza gains A FREAKING POWERFUL FLYING-TYPE MOVE THAT REPRESENTS HIS POSITION AS "EMBODIMENT OF THE SKIES", AAAAAAAAAAARRRRGGGGGHHHH. But yeah...if Air Slash were a TM, Charizard
might have been able to be my main aerial transportation.
Now...I don't know...I also saw advice at how using Fly in battles give the opponent a turn to set up (i.e., a free switch as they anticipate your attack) while you're invulnerable, and now there are many more physical Flying-type moves that are, for the most part, reliable. Said Flyer would also have to be a Pokemon I anticipate on using often who can also utilize Fly well, though not at the expense of another move. I guess come Generation V, I'll be able to determine said Pokemon. I just know that Fly will be overused as transportation once again! XD
