Grey is Black's little brother and secondary henchman.  He's obsessed with video games, and is almost never seen without some sort of portable game console.  He's very antisocial, but never shy; he just prefers his video games to social interaction.  He tends to be pouty at times, and can often come off as annoying to others.

Looking for a high pitched child male voice with a sort of spoiled/bratty tone to it.
