Ok my favorite is Arceus least favorite Budoof

My fav is litleon and my least fav is charizard

Do you mean the least fav? And I have Pokémon silver (I think) but it does have dialga on the cover

But if you have to ask me it's probably gonna be Entei. Gives me a final boss vibe when I played Pokemon Super Mystery Dungeon.

Favorite Pokemon is Cyndaquil (obviously)
And the least.. I don't even know.
