On the Number of Pokemon Moves

As of this writing, scholars in this field have identified more than 600 distinct moves that can be used by Pokemon in battle.

Yet each Pokemon is only able to remember a maximum of four moves at a time. To learn a fifth move, it must forget one of the other moves that it knows.

Additionally, it must be noted that there are also many different way through which Pokemon are able to learn moves. There is still much for us to learn about the relationship of Pokemon and their moves.
