The son of Hector and Major Doctor Ghastly which is Destructicus Con Carne is from the future and comes back to say hi but incidentally tells his parents what happens in the future and that he's a protecter of truth and justice.

Major Doctor Ghastly invents the Temporal Confabulationater Izationizer Unit -- a time machine that works so well that Ghastly, Hector and Skarr end up meeting their future selves and Destructicus Con Carne, son of Ghastly and Hector, as both an infant and an adult.
