There are a lot of Pokemon and each game allows one to build a different team and use.
However, there are Pokemon one doesn't get to use during an in-game run either for being a huge investment, being a trade evolution (and not having access to someone to trade at the time), being post-game exclusive, only being accessable one or more generations later etc.
I think there are a lot of Pokemon where people theorycraft how it would perform or generally wanting to try out just because of a certain desire like me wanting to use Golem or Alakazam in Gen 1 which bothered me a lot.
However the Pokemon I want to pick is a Pokemon I wanted to own in general, not only for an in-game run, but to use it perhaps even competitively.
That Pokemon being Celebi:




Until Pokemon BW was released, I have never been able to get my hands on Celebi. Even with friends and many tricks we discovered, we could not find ways to get it. With Gen 5, online trades became far easier and I managed to obtain one even after. In Crystal, I managed to finally use Celebi through Virtual Console.
Tho to this date, I still have no Celebi in Gen 3 or Gen 4 games. Even with Glitches there is no way to obtain them, at least from my knowledge. Probably some risky Pomag Glitch which requires Pokemon I don't have.
The general appeal on how hard it was to obtain at the time is what makes it so desirable for me.
So what are Pokemon you would like to use in-game?
