Mimic Move Details

Mimic Move Details
Type	Normal
Power	—
Accuracy	100%
PP	10 (max. 16)
Effect	Copies a move from the opposing Pokémon’s move list.

In Gen 1, Mimic lets you see the opposing Pokémon’s move list and select a move to copy. So not only can you potentially take a powerful attack from an opposing Pokémon, but revealing their moves can also help you strategize new ways to beat them.

Another quirk of Gen 1 Mimic is that the PP of the copied move is the same as Mimic’s PP after it’s been used.

For example, if Mimic would’ve had 9 PP after successfully using it, then the copied move will also have 9 PP. Even if the copied move’s max PP is lower than that of Mimic’s, it will still have Mimic’s PP after being copied.

There’s a number of Pokémon in the game who have good stats but a weak learnset. For these kinds of Pokémon, Mimic might be a good move to teach.

However, keep in mind that the usefulness of Mimic’s copying abilities is dependent on the moveset of the opposing Pokémon you’re fighting.
