Ok...I'll try:
The diferents vehicules we use in the game?

Find me by land, or much later by sky(your first vehicule is the chocobo to pass the midgar zolom,who can only walk,and it's just on the cd2 with the highwind that you can go by the sky)

When doom is at hand, the first option will die.(at the beginning of the 2nd disk,the buggy and the Tiny Bronco,your first 'set' of vehicule,have disappeared)

Twice I'm there when you've escaped via rope;(the first time you escape via rope,the turk helicopter is there,and later in the game you can use elicopter in junon.The second time you escape with a rope,the highwind is there)

Once while unconscious and regaining hope.(there I really don't know)

It should be noted, I've more than one form--(well,you have birds,plane,etc...)

Sometimes I'm chilling, but usually I'm warm.(hum...well,most of them and the chocobo sould be warm,but the tiny bronco and the submarine sould be colder than the other 'cause they are in water)


If you are dextrous, then carry me well(well,only the pilots can use the tiny bronco,so...they need to be dextrous....)

To coax divine pow'r from an old corpse's shell(I don't understand completly this sentences,so I don't know...)

Sorry if my explanation are not clear...but I speak french irl,and my english is not perfect
