1v1 Mode

1v1 Mode was the first mode introduced in Pokemon Tower Defense: Generations. Instead of tower defense battles, you put one of your pokemon out against one of your opponents pokemon. It follows the adventures of Joey in the PokéMatrix, an invention of Prof. Oak meant to enhance your skills as a pokemon trainer.

Description
Prof. Oak is your opponent. The battle happens in his lab. He will send out 3 pidgeys to face you. On completion of this level, you will be able to buy a rattata.

Strategies
Eba's First Playthrough Strategy:

On your first playthrough, your recources are limited to a Weedle or a Caterpie. Either one is fine for the level. All you need to do is put the speed up high, and leave the attack going, and you'll breeze through the level. Sometimes, you'll loose. If you loose repeatedly, try using string shot once in the battle.

Eba's Geodude Strategy Part 1:

If you have unlocked geodude, you simply need to finish the level by repeatedly using tackle. Nothing special. It is vital you folow this strategy to be able to continue to Part 2 of my (highly effective) strategy that will eventually lead to completing the checkpoint.
