Galilean

Galileans are bulky aliens with rocks covering their body. Because they themselves are living planets, they do not live on planets, and instead live in space. If a Galilean takes a large amount of damage to their core, they could meltdown and explode, much like an actual planet.

Appearance
Galileans are bulky, rock armored aliens. They are red in color and have a core on the center of their chest, they have four red fingers and three gray toes. They wear black pants with green stripes on them, they have black marking on their face as well as a big mouth. Their face consists of a large mouth, green eyes, and black markings. In essence, they are considered to be living planets.

Powers and Abilities
Galileans have the ability to manipulate gravity; to either make objects lighter than air or incredibly heavy.

They also have the ability to levitate via gravity manipulation.

Galileans can make objects revolve around them and can roll up into a planetary sphere.

For all orbiting processes, Galileans can roll up into a planetoid sphere.

Weaknesses
If a Galilean takes large amounts of damage to their core, they could meltdown and explode, much like an actual planet.

Their large size makes fitting in smaller spaces difficult. It is also shown that sudden changes of mass can throw off their orbit.
