Bagon is the first stage of Salamence (Dake's best Pokemon, which is Dragon and Flying type). You can find it in the smallest room in Meteor Falls. On the rectangular piece of land, you will find TM02 (Dragon Claw), which gives Attack 80 and Accuracy 100. Bagon evolves into Shellgon, then into Salamence. Salamence is like a fire dragon; cannot learn water attacks, but can learn Flying, Fire, and Dragon attacks.
