"Weezing loves the gases given off by rotted kitchen garbage. This Pokémon will find a dirty, unkempt house and make it its home. At night, when the people in the house are asleep, it will go through the trash."
Another Pokemon associated with being evil because of its association with certain groups, it's hard to deny that Weezing doesn't at least look evil. I mean, it's basically two toxic heads put together. How can that not be evil? It's obviously most famous for its partner James, but it's been used by many other trainers too. Including Ash in a special Gym Battle.
Weezing's Basic Attack is Acid while its Special Attack is Shadow Ball.
