My ability only dog-like PKMN and canidae member PKMN can have.It's called Wild Nature.It allows the user to be the strongest and wildest PKMN in battle.Therefore,if you tell it to do one move,It'll combine 2 moves in 1 and sometimes learn a different move.Then it strikes the foe and in one hit,the foe is knocked out! I wish I had a PKMN like that.....
