Mercury

Mercury is the first planet from the sun.

Personality
Mercury is a child, and as such he is very curious and naive. He falls for tricks all the time, and likes to run around in circles. He enjoys spending time with Jupiter, but doesn't understand that when Jupiter calls him "Little Baby", he is just teasing him, so he gets mad.

Appearance
Mercury is a small grey sphere with numerous craters, ridges, and hills. He has large, round eyes with grey pupils and often a "cute" expression.
