Never in any Pokemon game can you "Catch em all".
(UNLESS you cheat with the Action Replay) -LOLz.
Yes. You can catch every single pokemon in the games.
No to get Cyndaquil you must catch all Pokemon from that region, because if you have to catch every single Pokemon, won't you already have Cyndaquil?
You have to catch every single Pokemon except Celebi (of course) then you get the GS Ball from Kurt in Azelea Town. To catch every single Pokemon, you HAVE to trade from other Pokemon games, it's pretty difficult to get all of them.
u get national dex
After you catch every single Pokemon on the national dex and the sinnoh dex. You can always shoot for the 100 strait win at the battle tower, defeat the master rank Pokemon contests, look around for people you might have not battled yet.
I think the only way is to hack, they purposely made it so you have to trade Pokemon to catch every single one
to catch zapdos in pokemon black you have to have every legendary pokemon
you cant catch every single Pokemon in one game. you need to trade to get certain Pokemon. you wont find a meowth in red, so to get one, you trade someone with blue. and certain Pokemon evolve through trade like haunter or graveler.
if u catch every single Pokemon including the ones from the national pokedex, then u can hav fun and battle frends etc. or u culd start again.
No not every pokemon. You can't catch the starter Pokemon and many of the rare pokemon, you have to trade with Diamond. sorry ...
yes you can catch every Pokemon ever made
No the catch rate is the same in every game
