Star is pretty much Daron's self insert for sure, Starfan13 is also her self-insert, her birthday is in november just like Marco's and she took the GED because of her bully, while for some reason they made Marco do this.... So I guess you could say Daron put many of her own experiences in just every character. There was an old picture of Daron having her hair dyed a bit lighter and with one teal stripe and Janna's beani as well...>>112212899
As the anon says, it's true, Daron at best said that Marco had a little tiny bit of her husband in him, but that he was originally quite different, according to the few information we have he was black belt, Star's other enemy besides the Stacies in general, and had so little participation in her life that he didn't turn into anything other than a friend on the long run, all of this in how long? 20 years in Daron's hands?
It seems that when they decided to make the show a "girl's show" they decided that a guy being notoriously better than the female MC was going to slap them hard, but it still backfired on them, proof of that is the Cuckquean fanart and how hateable Star ended up.
