Mercury is another being of my worl (aka Ruunifurr) and is my space sona! He's shy & spends time painting the stars. His job is to shape the world around him, but when he meets Grimace, he is offered a life among human beings, to see what its like to be normal. Turns into pure Mercury when threatened, hair sticks up, and grows an extra pair of arms when in danger. Can scream loud enough to kill a normal human child's ears (age 8 & lower) Is 2056 space years old. Protective over close ones.
