As his name suggests, he likes blue and wears it a lot. He's kinda rude. And he's a criminal. But other than that, nothing really much else to say... Oh, also he's in a crime gang with two other people. them being:

Muhammad: Nobody in the gang likes him, because he's annoying and he says cheesy/overused movie quotes. Secretly might be depressed because Blue Fedora Hat Guy and Johnny HATE him.

Johnny: Johnny can only speak in choir and likes the color red, nothing really else to mention.
