Portable, sturdy, and built within seconds, the invisible walls of Mr. Mime are a vital tool in emergencies, although their invisibility makes them hazardous and they require constant concentration to maintain. Whether holding back a river when a dam breaks, holding up the ceiling during a cave-in, or even deflecting meteors, there is little which a sufficiently large group of Mr. Mime can not do.
Apart from their obvious utility among rescue workers and in emergencies, Mr. Mime are also used in the construction industry, for a temporary invisible wall can be quite useful to have until it is slowly made to disappear as a real one is built in its place. And like all pokemon, Mr. Mime do battle, weakening physical attacks with confusing reflections or elemental ones with screens of light to protect themselves and their teammates.
Occasionally, a Mr. Mime which has not been careful in the relative placement of its walls can find itself trapped in an invisible box. This creates an unsettling, claustrophobic feeling in the Mr. Mime, and the box will not be allowed to fade away, but is instantly dissipated with a blast of psychic energy more powerful than any it can produce in combat. Trainers should be advised to take special care to avoid allowing this to occur, for there is no defense from the flying shards of an invisible wall.
