The Great One is a giant tick like creature that has the ability to consume a planet by sucking all the energy from it until the planet implodes on itself. When doing this the planet will change to protect the tick, which made it hard to attack. The tick also has a tough shell that is nearly impenetrable until it sheds.
- When The Great One is in the process of shedding it will secrete gooey liquids from its body. Some of these fluids are acidic.
