Pokémon Ruby and Sapphire/Fridge

Fridge Brilliance

 * In the Devon Corporation building in Rustboro City, there is a scientist who mentions that "I'm attempting a device that lets you see into the dreams of Pokemon!! But it's not going well..." Two generations later, you get to do just this in Pokémon Black and White.

Fridge Logic

 * The player witnesses Wally capturing a Ralts as his first Pokémon with Norman's Zigzagoon. We then see Wally give the Zigzagoon back. The Ralts, however, is at such a low level that it doesn't know any damaging moves yet. How is Wally supposed to level up his Pokémon if he can't have it fight or use it to catch other Pokemon to help gain experience?
 * Com Mons tend to be easy to catch even if you don't weaken them first. Perhaps he just kept tossing Poké Balls until one finally worked, and then used that Pokémon to help him level up his Ralts.
 * Or, he just used a Rare Candy, to get his Ralts to Level 6... boom, Confusion.
 * Struggle.

Fridge Horror

 * In this generation, no message is given when you lose a Pokémon battle. You are simply told that you whited out- and then wake up in a Pokémon Center...


 * Team Aqua wants to flood the earth. Team Magma wants to cause droughts and dry up the land. Both of them unleash a creature that can do that and proceeds to begin to do so in a wildly out of control manner. Now imagine if you weren't there to stop said creature.
