The CRK-721. A robot built for combat and bred for war. It's element remains unknown but legend tells that it was born from the very metals that forged Herobrine's blade. Not much is known about him residing the fact that it holds knowledge beyond comprehension and that it's very metals burn with every touch of human flesh.

The machinery inside it is completely beyond all the Steve's comprehension. Many have believed it to be a spawn of Herobrine himself in an armor powerful enough to conquer all of Minecraft. Its name's meaning remains unknown...

Truly a robot worthy of defeating an entire army of Iron Golems alone...
