Darthatron was a samurai for the Sentinels in the original LEGO Universe. However, in the midst of a battle with the Maelstrom, he was struck down. Half-infected, he managed to escape to the dropship with everyone else, and he went back to the base. After recovering, his right arm was the only part still infected. It was infected for too long, and they didn't have the technology to repair it yet. He was instructed by Wisp Lee to control it and he became a Paradox Shinobi. It took him a few years to train. Eventually, when he was finished training, he heard of everything that had happened in Sector 9. Upon hearing this, he decided to return to the Nexus Force, and go the Sector 9 to help with the war effort.
That's my character. Any suggestions? Leave them in the comments.
