Scaylion Queens are very large Scaylions with general appearance similar to that of Diseased Scaylions but almost twice larger, with more health and are much more powerful. When Scaylion Queen makes her appearance she will always produce three waves of Scaylion Bugs, each wave with one Bug less than the previous one.

Scaylion Queens never leap at their prey but approach at steady but rather fast pace. Once they get in close, they unleash series of blows with their pincers. This attack is powerful enough to completelly strip down all but strongest of shields. They also spray their targets with stream of corrosive liquid. This attack is easy to avoid as they tend to stay in place and spray the liquid in a fairly limited horizontal arc.

Scaylion Queens are quite resistant to incendiary but very vulnerable to corrosive and explosive damage.
