The Brickannunaki of Niblockyburu came down and genetically altered the Blockhead, making them into a cyborg master race of slaves for when the Brickannunaki return with their leader, Badspot, once more, to finish what they started: Gifting the cyborgs with a TF2 style character customization, so that you too can look like Gundam and blast holes into people's holes. And they, the Brickannunaki, shall smite their enemy Piecrust, leader of the Goblins, and destroy his servant Sauronblock for all eternity, disposing of the Ring and reviving the Tardis.
