Mirror is an ability found in EarthBound/Mother 2, and is utilized by Poo. It allows him to become an enemy and use its abilities, although it only works on certain enemies, and has a fairly low success rate. The enemy abilities do NOT cost PSI points unless they are PSI abilities, so in a pinch, it can be used as last resort if Poo is out of Psychic Points. It can cure all status ailments except for certain ones like, Diamondization and Numbness. And enemies will not attack Poo in this form.
