dude you have to cheat for that
there isn't a cheat but you can trade them over from other Pokemon crystal versions.
You pick it as your starter pokemon. Otherwise you will have to trade or cheat.
You can obtain it from Oak as a starter, use a cheat, or trade.
You could cheat or soft reset.
your question Doesn't make any sense , you can't change the 3 starter Pokemon. and what is "this a cheat" mean? use action replay to change starter Pokemon into what you want. you might need pokesav.
You need to have a walkthrough wall cheat and skip getting the starter pokemon.
unless you cheat you have to evolve piplup which is a starter Pokemon
check it up on neoseeker.com and you might find it.
well this isn't exacly a cheat, but it is a very good idea and it works. First start your game and choose one of the starters, Secondly talk a friend who just got the game into trading one of your Pokemon for a starter Pokemon. then after you trade, your friend can delete their game and start again with the starter Pokemon you don't have, then trade again! Then... Viola! you have all three!
turn it off n front of the Pokemon 1000
The only other way is to cheat.
