Major Psychic Psychos are able to protect themselves with a PSI Shield Ω and can also wield Paralysis α. Lastly, they can wield both PSI Fire β and PSI Fire γ.

Major Psychic Psychos often appear in groups, raising the difficulty of the battle against them. They are vulnerable to PK Freeze and PSI Starstorm.
