Apollo, Adama's son, was the goody-goody of the original series. Despite living in the shadow of deceased brother Zack (Rick Springfield!), Apollo led the Viper pilots against the Cylons and even adopted his dead wife's son Boxey. Apollo also had the distinction of coming back from the dead, thanks to inhabitants of the Ship of Lights. He didn't appear in "Galactica 1980," but his adopted son was one of two pilots chosen by Adama to live among the humans.
