''Shapes made of four coloured blocks, like a T or a box, come down like falling bricks' (Tetris)
'I, am Mega Man! I got a motherfucking gun for a hand!' (Mega Man 3's opening music)
Also known as Brent Black is the fourth cousin of Rebecca Black. He stole her musical talent like some highlander shit except without killing her. He often only uses his talent on putting lyrics to dorky retro video game titles. Unfortunatly, Rebecca Black still insists on singing even without her talent.
