Grey is an alternate universe version of Drummer Ross Federman 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. Grey is the creator of stars, stars will often form on their own in his pockets, he also has the ablity to make constellations and larger stars, but he cant keep then big ones from exploding. he is very squishy, but squishing him makes him dizzy, and can be quite gullible.
