Blank was a star thirsty for power, but he brought too much. He used to have a face like other stars. The stars had no idea what to call him, so they just dubbed him as "Blank". When Blank first came across seeing the powers of other stars, he was amazed. He was then taught by those exact stars. When he shown off what he was taught, lots of stars were jealous and starting booing him. It drove him insane, and then the worst happened. Millions of stars were unalived by Blank. Luckily, Galaxy and Celestial sealed him away to prevent more harm. Some people say he's no longer here with us, and some others say he's working with D.L.M. But the truth is, he's still sealed away, waiting to be free.
