Marker is a humorous, quirky, loyal, determined, and cheerful character who likes playing weird games such as Toss the Dirt and Eat the Dirt and he doesn't seem to be very intelligent. He can also be a bit of a devious trickster sometimes, when he presses the "up" button and keeps running up to get in The Strongest Team on Earth's way. Despite his unintelligent mindset, Marker does have a level head when a situation gets out of hand. Probably fidgets with a bunch of stuff.
