"Magnetic fluid controls an alien mechanical body": This alien is composed of a special magnetic fluid, and the body can flow and deform freely like a liquid. Its surface is covered with a transparent magnetic film, which can adjust its shape and structure according to changes in the external magnetic field. In battle, it can instantly turn into a sharp sting ball to attack the enemy, or it can turn into soft tentacles to wrap around the opponent. At the same time, it can also use magnetic fluid to control surrounding metal objects and build powerful fortifications or attack weapons.
