PK Shield is a PSI move only Ribbon can use in the PMDS Rp. When used, a psychic shield envelops one or more allies. This reduces any and all physical damage they might recieve. It only comes in three layers, so once someone gets hit three times, they need their shield renewed. It comes in only two stages. It originally came from the 1989 video game Mother.
- α(But one ally is enveloped by a shield.)
- Ω(All allies are enveloped by shields.)
