Origins
THE SUMMER OF '62. PORKO Industries are unleashing a super-weapon on the Ancients in a war called The Battle to go on to the Future. Thus they made a giant robot making him canonically on BMU scale the Largest thing. He was about 543 BMU's breaking the record as largest on BMU scale, breaking the record of most BMU's to former champion Combo at 180 BMU's. The programmers of his AI have been so smart since he had many battle strategies and also was in the war without a single scuff. That just proves that he's a powerhouse. Fast Forward to now Array and Lilith are in the forest. He saw Evangelion all mossed up and washed all of the moss he gained over the years. He was unconscius so he was controllable but Array turned on his conscience and thus he was in an all new era.
