A highly evolved form of slimes, Queens possess a larger core then other slimes accompanied by multiple satellite cores. This allows a Queen to have multiple independent bodies. If the Queen's main core is destroyed, it can be regrown from any of her satellite cores.
Slime Queens have a large potential for mutability, they are able to combine abilities effortlessly and even create new ones by studying what they have copied. They are also able to copy an all innate abilities like a Knight and can handle a larger difference in power.
Any non-organic material they consume, including gasses, is stored and can be used in the same manner as a Knight. In addition to this, Queens have the ability to combine those materials at will and craft objects with them as long as they have seen a blueprint, schematic, or reference. Transmutations are possible but the further the materials are apart in composition the higher the loss will be.
