The powers granted to senshi vary based on the nature of the body to which they are bound, but the consistent ones include: the ability to manifest their star seed as an externalized 'sailor crystal' that can be passed on to another creature, significant extension of lifespan bordering on immortality if not killed in battle, the ability to transform into a 'guardian' form granting enhanced strength, durability, speed, and healing relative to others of their species, and the power of teleportation and psychic sensitivity to malicious magic and hostile alien entities.

Evidence suggests that passing on a sailor crystal does not cause the individual who was born with it to lose their powers.
