Marty is the neighbor of Vera Tennyson.
He had short grey hair with glasses. He wears a tan shirt and has alot of missing teeth, probably because he is so old.
He appeared in Permanent Retiremant where he was taken over by Limax. Throughout the time he was being controlled heattacked Ben and almost escaped but in the end the limax was defeated and Marty was free not remembering anything that has happened.
