A GELF (Genetically Enhanced Life Form ). Prototype genetically engineered soldier, Alpha Model K.
Dagwood is a GELF, also known as a Dagger. Being the prototype, he did not turn out exactly like his creators had planned. He has enormous strength, but a soft heart, and was not overly quick with his intelligence. Thus, he was not a suitable warrior.
Not considered a threat to anyone, he was assigned to the seaQuest as a janitor. After saving Tim O'Neills life he soon became a valued member of the crew. He soon had many friends, including Piccolo and Lucas.
Dagwood had lived an extremely protected life, and had trouble understanding the outside world, though he slowly improved as he spent more time with people.
