You must complete some stuff. Yu have to get the national pokedex(yes, 60 pokespecies and then prof oak) then you have to get Sapphire and ruby for Celio
You can always fight the Elite Four again. That allows you to find Mewtwo again. It worked for me in Pokemon X. It is best to save before you make it faint. Do so BEFORE you enter their caves! SAVE BEFORE BATTLING LEGENDARIES.
Choose a Pokemon that has a high level (especially Speed) and is resistant to attacks by Entei. Also if you can use the attacks Mean Look and False Swipe, victory is certain. Try to use a luxury ballor ultra ball. Use the Marking Map App. in you poke watch/poketch to track the Pokemon.
Well, you can find the usual quagsire, bidoof, bibarrel, croagunk, wooper, starly, staravia, skorupi ect. But some new Pokemon are tangela, yanma, toxicroak, drapion, ect. I am still questioning about kangaskan though. =] well i heard that you can also catch two ledgendaries and i heard the two was mew and mewtwo (lie you can not catch mew or mewtwo)
you have beaten the game but if you want you can catch mewtwo if you still have'NT and you can also challenge the elite four again but beware cause their Pokemon will be around lv 60 and 70 i think theres also a lv78
Yes you can rematch greevil at anytime and he will still have his shadow Pokemon if you defeated them.
Mate, I'm still trying to answer that one myself...
Catch mewtwo and you can still battle the elite 4 anytime, but note, they get harder everytime

Mew is not in in Pokemon SoulSilver. There was a Mew event however that has ended on February the 11th. You can still catch a Mewtwo in Cerulean Cave at level 70.
Beat the elite four and get mewtwo
YOU CELEBRATE BECAUSE YOU JUST CAUGHT THE MOST POWERFUL POKEMON! (debatable if you compare it to Mew) Just migrate it to DS game and/or train it up. If you still have some Pokemon to catch for your pokedex then I guess you can do that.
im still tring to firgure it out but when i find him i will give u the answer

if your party is not full
You can't get into cerullean cave(the cave with mewtwo in it) on Pokemon silver because according to the game's story, the cave has caved in, but there may still be some remmants of the cave you could get to via a gameshark.
Mewtwo is a recruitable pokemon only through the recruit point using a ticket and in order to receive a stronger Mewtwo make sure you utilize a Mewtwo ticket at a recruit point that is in a later rank (the best being EX). If you use the ticket in EX you will get the strongest Mewtwo possible (not guaranteed as the strength number will be completely random but it will still be really strong regardless).
nothing really unless you still have more Pokemon to catch POKEMON GOTTA CATCH 'EM ALL!(or do you?)
