Zero.

Maxwell's second attempt at bringing an Eye of the Beast into our universe.
Zero possess the ability to change into any form he desires, but mostly takes the form of a simple black
figure with glowing green eyes and a zero symbol carved into it's chest when he is fighting others.
It was in this form that Zero began a brutal attack on the city of Kargeth during the events
of the Mini-movie Song of the Void
During this time he displayed the ability to resist any form of attack with seemingly no
effort, however Zero failed to maintain his powers for long being eventually seemingly defeated
by a Dimensional Guard security agent known as Arthur.
