Blue is an alternate universe version of Bassist Zubin Sedghi from the band Tally Hall, the au is where all seven [ including honorary members] members are cosmic beings and create the cosmos as we know it. Blue is the Keeper of planets, he is very petty and nitpicky with design choices, he is fairly easy to impress and the most patient of all of them, he checks on his solar systems sometimes and has problems with asking for permission.
