Remora

Remoras are a species of marine Archenemy with the ability to control others.

Description
Remoras were originally described by the Roman academic Pliny the Elder. They are slimy and legless, resembling sea leeches, and have suckers on their back that let them attach to objects. They can enter a person's body and attach to them, gaining control of their body. They can also stop even large ships from moving by attaching to their bottoms.

Remoras have a mutualistic relationship with Leviathan. As Leviathan's immense size means that there are many spaces it cannot enter, it uses the Remoras to control people and force out prey from these small spaces.

Trivia

 * The Remora is based on the real-life family of fish of the same name and on the legendary creature Echeneis, the latter being itself based on the real remora.
