CR-1012 in the Berserker Corps started off like the others; An expendable tool of war fighting an enemy far outclassing in blood lust. throughout the Great Wunder War he stood out from the others in his skill and defeated a Megarlo-Titan. he took the Shield from the rider and kept it as his own. modifying it, he became known as Dan Smasher: The ‘MEGA-SLAYER’ and ascended to become the Type of Berserkers trained to take on the toughest Targets facing the Empire: A Champion Class. He survived the war without losing a single fight or dual. Such a Unit like himself became a legend among many. Afterwards he unfortunately took part in the Fallen Campaign which occurred after the 1st Great Wunder War was over.
Because he was able to break the Curse embedded in his programming he refused to assist in gneociding species which included the pony race. He went AWOL and became an Adventuring Mercenary taking on contracts which involved slaying monsters, wanted targets and protecting towns and cities. He met another Berserker Named Crossover who was Aided by Katka. for a while they bumped into each other and helped each other.
