Mayberry Melonpool is the television-addicted, somewhat clumsy, not-all-that-intelligent Captain of the "Steel Duck." Oh yeah, and he's obsessed with getting a date. In short, he doesn't have a lot going for him.
Old Ralphie is the only survivor from the original Melonpool universe that we've encountered so far. He's essentially the product of Ralphie being caught in a 30-year time loop. He's currently searching through time and space for his lost wife and son.
Seems ominous somehow.
Well, clearly he failed, because Melonpool is still here…
Alternate timeline? I forget the technical explanation but it did come from Star Trek. The Abrams movie, granted, but still Star Trek.
