go to the safari zone, use your super rod to fish, in any area. And you should be able to get a dratini
Buy them.
You can get one by fishing with a Superrod in the Safari Zone. But the easiest way is to evolve a Dratini (at level 30)
The easiest way is to print out a map off the internet
The best way to get Dragonair in Leaf Green or Fire Red is to envolve it from Dratini. You can get Dratini in The Game Corner in Celadon City ( The city where you battle with the GYM 4 Erika Grass TYPE).
You have to evole from Dratini and Dragonair. I don't know of a way to catch him in the wild.the way you can catch is go to the safari zone and use the super rod in the water.
The easiest way is by using Surf and going south from pallet town.
On Pokemon FireRed and Leafgreen you can catch Dratini and Dragonair in the Safari Zone while fishing. I caught a level 18 Dratini and now have a level 59 Dragonite that almost singlehandedly beat the elite four. The best way to train Dratini/Dragonair is to teach it Flamethrower/Earthquake and fight a dude with three level 28 magnetons that in total give close to 3000 exp.
You can't. In no way is it possible to get Totodile in LeafGreen.
Just battle weaker but still strongish Pokemon until you are strong enough P.S. save before trying Pokemon league until you eventually win
To get a shiny Dratini in Pokemon Crystal you need to find one in the wild or hatch one. This is extremely rare though with a 1 in 8192 chance of the wild or hatched Dratini being a shiny. There is no way in Pokemon Crystal to improve these odds.
One way is to go to the Celedon Game coin thingy, and buy it for i think 6500 coins. Other way is to go to safari zone and use super rod in any body of water.
Gligar is a flying and ground type of Pokemon. The only way to get this Pokemon in LeafGreen version is to trade for it.
