No Guard is an ability introduced in Generation IV that allows all the user's and the foe's moves to never miss. This includes the semi-invulnerable turn of moves such as Dig, Fly and Skull Bash. It can also hit a Pokémon using Protect or Detect if the move has less than 100% accuracy. The lower the accuracy, the more likely that it will hit. Moves like Magical Leaf and Swift won't hit as they have perfect accuracy and One-hit KO moves like Sheer Cold will hit as they have terrible accuracy. Also if a Pokémon with No Guard is at the front of the party, it increases the Wild Pokémon encounter rate.
