A shield fiend is a mindless parasite made up of quasi-energy and protomatter. When one collides with a ship it feeds on the ship's shield energy.
- A shield fiend instantly damages all the shields on the ship on which it is played and is then discarded.
- This card cannot be played on a ship with an invinco guardian.
