By 2121, all humans had fled to the planet Galacty II, after Dark Mark created a portal to the world of Minecraft. The Minecraft monsters then came out through this portal and destroyed everything around, sowing terror among the inhabitants and making their prisoners their slaves. These slaves had to harvest resources in the world of Minecraft, transport them to the normal world and build a fortress for the monsters. The humans gathered all their resources to build three rockets, InterGalaxySave I, II and III. Most of the earth's population thus escaped from the earth, but the most skilled Minecraft players remained on earth and promised the others to contact them if they ever succeeded in freeing the earth from the monsters and closing the portal. Thus, the humans left the earth, leaving to those who had remained important documents that should especially not fall into the hands of the monsters. The Minecrafters who had remained on earth formed an alliance among themselves called WorldSaving. They vowed to stay together and never to declare war on each other.

The monster fortress had meanwhile been completed and they had put a magnetic field all around that destroyed all living things that passed through it. The humans then decided to build robots which they called Barrier Breakers, and which, as not being alive, were able to cross that barrier. With these robots, they would spy on monsters and attack them, disguise the robots into humans so that the monsters wouldn't find out why the "humans" got through the barrier.

And it's the skin of one of those Robots, BarrierBreaker058, leader of the spy squadron here.
