Yes, but you need to beat them 40 times, then you go and catch a shiny geodude (red geodude) then you give it to the man on 1 island in the big Pokemon centre, he will give you a rare ticket, and you can go to the hoen region to catch him.

It doesn't matter how many times you beat the elite four, celebi is not going to just appear.
mewto: curulean cave after beating the elite four, really hard without master ball, i still haven't succeeded mew: curulean cave after beating elite four 5 times (i haven't proven this one yet, might not be true)
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
I heard that you must go to "heaven" by beating the elite four, 100 times... It might not be true...
You can catch latias anytime after beating the elite four in ruby, sapphire and emerald.
unfortunately there isn't any. exept finding mew in the lost cave after beating elite four 111 times
you must beat the elite 4 twelve times go to where you caught mewtwo and catch mew :)
Do you mean a Charmeleon? You will find it after beating the Elite Four 3 times. It will be a Charmander though at lvl. 5. Hope this helps!
