Marker is good-natured and cheerful. He also loves to play games. His favorites is Toss the Dirt, i.e. digging the ground, and Eat The Dirt, i.e. eating the dirt off the ground. He's not so good at Rock-Paper-Scissors, though, because he keeps getting his fingers twisted into weird shapes. He's quite dumb and innocent and some people think he's weird. His purple ink is like his blood, and he easily cries from deep conversations and physical pain.
