You can use the pulldown menus above to choose a Pokemon.

You can see where each Pokemon can be found in the gameboygames, how strong they are and what attacks and skills they have.
You can also see to what Pokemon they may evolve or from what Pokemon they have evolved.
There's also a short description of the Pokemon and some other details like height and weight.

An icon of a speaker () below the Soundbox means there is a sound available of that Pokemon. When you click this icon, you will hear the Pokemon.
