What is effective on all of the Pokemon types?

There is no move or type that is effective on all Pokemon types. This is because the Pokemon type system is designed with a rock-paper-scissors style balance, where each type has strengths and weaknesses against others.

For example:

* Fire is strong against Grass and Ice, but weak against Water, Rock, and Dragon.

* Water is strong against Fire and Ground, but weak against Grass, Electric, and Dragon.

This intricate balance is what makes Pokemon battles strategic and exciting. You need to consider the type matchups and choose your Pokemon and moves carefully to maximize your chances of winning.
