Stantler

Intimidate : When this Pokémon enters battle, the opponent's Attack is lowered by one stage. In a double battle, both opponents are affected. This ability also takes effect when acquired during a battle, but will not take effect again if lost and reobtained without leaving battle. This ability has no effect on an opponent that has a Substitute. Overworld: If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.

Frisk : When this Pokémon enters battle, it reveals an opposing Pokémon's held item to all participating trainers. In a double battle, if one opponent has an item, this Pokémon will Frisk that Pokémon; if both have an item, it will Frisk one at random.

Sap Sipper : Whenever a Grass-type move hits this Pokémon, its Attack rises one stage, negating any other effect on it.
