It doesn't matter how many times you beat the elite four, celebi is not going to just appear.
no
No, mew can't be caught in leafgreen It can only be caught in emerald after going to an event
Nope, you can only use it once. If you try to use Celebi twice for the event, nothing will happen. You will just stand there, just like if you didn't have Celebi.
There is 3 ways 1)Go to an event that is from 2-3 years ago so 2)To trade with some who has it 3)To buy an Action Replay and input the/a code P.S People Will Probally Say Beat The Illiet 100 Times That Doesnt Work But It Does Get Another Star On Ur Trainier Card:) That Will Get You Further To Getting 5 Stars. If you Have Emerald Or Saphire Not Ruby But If u Have 1 Of Those 2 Games Also if you have Sapphire you can beat the level 100 dudes then the battle tower will fall and you hurry and get out of it. But the tower makes a bridge to the secret islands go to the golden island go into the cave and keep going down till you see a shiny rock click on it and it will break then deoxys will jump out of it (Dont Use Your Master Ball, Save it for latias)
nothing
NO
Buy the next game
its not possible
no
you have to beat the elite four 5 times in both reigons ----------- No, it's only on FR/LG/E.
nothing happens. but people say if you beat the elite four many times, that a person drops a berry and it ends up being a ticket to birth island. but its not true. if you beat the elite four 12 times mew will then be wild inside curulean cave, and after u catch mew celebi will be wild inside victory road. EDIT: You don't get anything from beating the elite four over 1 time except exp points for your Pokémon. And as for "Mew and Celebi coming out" that is completely false. You can't catch Celebi at all in Fire Red or Leaf Green and you can only catch Mew if you have the pass for 8 and 9 island (birth island and navel rock) On birth island you can catch deoxys, when on navel rock you get catch Mew and the legendary pokémon Ho-Oh. The only other way to catch these pokémon is to use something like GameShark which is a cheating device. I wouldn't use it my self because cheating takes the fun and point out of the game and also it can harm your vba. (visual boy advance).
first you beat game then go to elite 4 beat it 10 times go to sky pillar with one lvl 100 search around for lugia you need 8 island(event), celibi comes from johto but people say after u finish the nat dex you can fight prof. oak, deoxys is on island 9(event)
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.
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)
unfortunately there isn't any. exept finding mew in the lost cave after beating elite four 111 times
