Dagwood

Dagwood signed aboard as seaQuest's janitor and became its gentle giant: a G.E.L.F. (Genetically Engineered Life Form) built for custodial work. Immensely strong, childlike, and frequently underestimated, he wrestled with questions of personhood in a world that considered him property, and more than once saved the boat outright.

Peter DeLuise (brother of castmate Michael DeLuise) played Dagwood from season two through the finale.
