Spirit
You are a noncorporeal entity: ghost, being of pure thought, etc. You are invisible and intangible (except to others with this meta-trait!). You can temporarily become visible, or even solid, but this is draining. However, your senses can perceive the material world at all times, and your magical or psionic abilities, if any, can always affect the physical world.
Spirit includes Doesn't Breathe [20], Doesn't Eat or Drink [10], Doesn't Sleep [20], Immunity to Metabolic Hazards [30], [[Insubstantiality]9 (Affect Substantial, +100%; Usually On, -40%) [128], Invisibility (Substantial Only, -10%; Usually On, +5%) [38], and Unaging [15].
Many spirit abilities from folklore are not part of this meta-trait; e.g., Injury Tolerance (Homogenous or Diffuse), Magery, and almost any ESP, PK, Telepathy, or Teleportation psi ability. Common spirit disadvantages include Compulsive Behavior, Dependency, Divine Curse, Dread, Maintenance, Obsession, and Weakness.
