Zero never imagined that, during a battle with aliens, he would be transported to the world of Evangelion.
He even ended up possessing a child named Shinji Ikari.
After that, in order to return to the Land of Light, which had been invaded, he desperately gathered Angel fragments. From then on, he unexpectedly lived a life of eating, sleeping, and fighting Angels.
"Shinji, get in Unit-01! The Power Angel has broken through twenty layers of armor!" Misato shouted.
"No, I don't want to pilot Unit-01. I want to become light, because only light can save this world! Hah, Zero!"
Shinji put on the Zero Eye Slugger and transformed back into the Giant of Light.
