"Grandpa" Maxwell "Max" Tennyson is the highest-ranking Magister of the Plumbers (noted as the leader of the Plumbers on some occasions), as well as the grandfather to the legendary Ben Tennyson as well as cousin Gwen Tennyson. He had two sons, Carl and Frank Tennyson, each the parents of Ben and Gwen Tennyson. He is married to Verdona Tennyson, an Anodite he met while on patrol who finds Max to have a "spark all his own" (referring to what she calls "The Spark" she normally finds in Anodites such as Gwen).
