Ganymede

Ganymede is the third and largest Galilean Moon.

Personality
Ganymede is often protecting his siblings, and generally has a short temper when it comes to the other planets. He is fine with Jupiter's caring personality, but the way the others treat him rub Ganymede the wrong way. Mars makes fun of him for not having colored eyes, something which he is very self conscious of.

Appearance
Ganymede is a small brown sphere with many patches of darker brown. He has many craters as well. His eyes, strangely, have no color, leaving them as pitch-black voids. Some of the smaller moons are scared of him because of this odd property.
