Oscar Explosion is the husband of Rose Explosion and the father of Nathan Explosion. He seems to have a military background and is the only of Dethklok's fathers to have a positive, healthy relationship with his son. He was revealed to have some resentment towards Nathan (or simply towards parenthood) because he had to buy "little kids" clothes instead of beer when his son was an infant as stated in "Dethfam". Later episodes however proved he does in general love Nathan, being one of the few people his son will openly consider "awesome."
