Beating the elite 4
After beating the Elite 4 12 times, the island where Mewtwo was on in Cerluean Cave, there will be a wild Mew between the levels of 60 and 65. There is only ONE. Other ways: Be at the Power Plant after beating the Elite 4 six times. Get it from Emerald at Faraway Island
You have to get a life. =)
No, you cannot own a Gym after defeating the Elite 4.
the best fire Pokemon u could have to beat the elite 4 would be blaziken over level 75 or higher
After beating red, challenge the elite 4. After beating them, red will reappear.
you keep on beating the Elite 4 and every time you beat the Elite 4 the the successful launches goes up one to two times i don't think there is a way.
you will go to Battle Frontier
the only way to do this is to either hack the game code or by using a gmeashark/action replay/codebreaker
No you can trade anytime before beating the elite four.
you complete the national pokedex, dont know about after that
