Marshall finds joy in the simple things in life. Curious and observant, he takes pleasure in finding a shiny rock or a new friend rather than any material object. He is shy when first meeting someone, but his friendliness combined with a sort of naïve charm tends to quickly endear him to others. Marshall has a tendency to have misadventures, but rarely notices that something is awry. He obliviously carries on whatever he was doing and somehow manages to always come out unscathed, whether it is a Spill spontaneously being created from his mud bath or him trying to tame a chime fish and catching one bigger than himself. Marshall owns a small store where he sells some of the items he finds. Mostly this is just an excuse for him to get to talk to customers and though he has a good eye for items, he leaves the bookeeping to an exasperated Kaien.
